Reflection on SIE 2016


Showcase
Initially, I was reluctant to enter the showcase, but with the support of my peer, I was able to step out of my comfort zone. It was indeed an eye-opening experience for me. From being selected to having 2 days of preparation for the actual day, my team and I were under a certain amount of stress due to the deadline for projects and upcoming exams. Nonetheless, we have been able to work efficiently and have come up with the best we can even though we had a time constraint. During the speech, I was anxious as it was my first time presenting in front of so many audiences. I was able to hide it well as my peers praise me that I did a great job as compared to the presentation I did in front of my classmates. Lastly, I was able to present without memorizing any script and was able to speak freely. To conclude my showcase experience, it was a memorable memory for me as I was able to work under stress.

Module & Project learning
Being able to write and speak confidently in the English language has always been my dream since I was young. In this short period of time, I was able to learn the ideal way of communication as we do have a lot of projects works with different teammates. Through this, I had learned the different ways to communicate with different people. It is impossible to have a ‘rubric’ for communication as everyone is unique. In addition, I also learned the different rules for writing an essay or summarising a report; the main key point, further explanation, fragments, capitalization, citation, etc. SIE 2016 had gained my knowledge in writing a technical report which I might need it in the near future. Working in a team is necessary for the working society. Thus, with the helped of Professor Brad, my team I am able to start the technical report smoothly. Although this might be the basis for increasing my writing skills, I would like to thank Professor Brad as I do believe this basic would bring me far in the future. Personally, I do think that there is a lot of assignment within a period of 3 months however it was not tough as compared to the other module even though lots of research are required. By having detailed researched, we know the reliability of the source. Reliability is important when it comes to writing a summary or report because it is important not to provide counterfeit statistics. To conclude, SIE 2016 is a module that will help me in the future in terms of writing, presenting and presentation slides.

Credits
I really appreciate Prof Brad for guiding me for these 3 months and encouraging me to step out of my comfort zone which I wanted to do it all the time but was not able to. I was a coward without anyone pushing me to that extent. Thank you, Prof Brad!

Annotated Summary_ Plastic Waste Management Recycling


According to a research article,” Constraints driven reverse logistics model for Plastic Solid Waste (PSW)”, (B. G. Mwanza, A. Telukdarie, C. Mbohwa) mentions that there is an increase of percentage of Plastic Solid Waste (PSW) in Municipal Solid Waste (MSW) over the years due to rapid population growth, urbanization, and economic growth. 
The authors state that several studies were conducted to compare PWS’s recycling or management between the household or community level in terms of both developed or developing economies.  Most items made of metal, glass, fiber and many other materials have been replaced by plastics due to the low cost and other beneficial assets. However, incorrect management of plastics will cause a massive negative effect on the environment. 
Within developed economies, the reuse of plastic waste has received considerable attention relative to developing economically. Works on wasted reuse have focused on the application of technology such as models and tools as developed economies focus more on industrialized recycling activities. Also, it was mention that there is a “correlation of recycling with levers such as income, age, education, gender and consumption patterns.” In response to this statement, things are not as superficial as how people often think the main reason people do not recycle was simply lazy.
Secondly, in developing economies, plastic waste accounts for 8-11% of MSW composition and only 4% of the waste generated in Africa is recovered. Furthermore, unlike the developed economies, most recycling operation is carried out by the informal sector such as the Non-Governmental Organization (NGO). There is a limit to what NGOs can do to help as there is insufficient funding to travel around to educate the public that is supposedly the government sector’s job.
The government needs to step in to assist the entire recycling system, no matter how it is developed or developing economies as they can implement the system and allow the public to adopt it.

Technical Report Draft_3


Background 

This proposal has been developed in response to a call for a proposal made by the Singapore Institute of Technology (SIT) to recommend solutions to improve the new campus, SIT Punggol. The team decided to work on plastic waste management in SIT Punggol, focusing on the beverages’ packaging waste.
According to the World Economic Forum (WEF) (2019), plastic production around the world saw a dramatic increase from 15 million tonnes in 1964 to 311 million tonnes in 2014. The article also mentioned that the number is expected to double again over the next 20 years.  As these statistics demonstrate, single-use plastics are a popular choice amongst consumers. As plastic production keeps increasing, the possibility of plastic waste will also increase.
As 8 billion metric ton of plastic waste is being produced in the world (Parker, 2018), it is crucial on how effectively it can be managed as plastic is a type of material that is difficult to biodegrade, which will result in it lasting a long time in this world. According to Wright (2018), plastics can take up to 450 years to degrade, depending on the exact type that was used to make it. As such, if the plastic waste is not properly disposed of will cause a variety of problems. One of such problems would be water pollution. When plastics break down into microplastic, it enters the food cycle of sea creatures causing harm to the marine biodiversity. Also, when plastics breakdown, it releases toxic chemicals into the environment and can make their way into our food and water resources (Grabowski, 2018).
Sriring (2018) published an article about a pilot whale that died due to 80 pieces of rubbish pieces found in its stomach has garnered global attention. According to the UN Environment Programme (2017), every year about 4.8 to 12.7 million tonnes of plastic are dumped in the ocean. Singapore contributes to plastic pollution in the ocean through its high usage of plastics in the country.  According to a study by the Singapore Environment Council (SEC) (2018), Singaporeans use at least 1.76 billion plastics such as bottles, bags and other disposable items yearly, in which only less than 20% are recycled. Also, SEC mentioned that the plastic waste is discarded, burnt or transported to landfills.
This is an issue to a city like Singapore as the majority of Singapore’s non-recyclable waste is incinerated and shipped to a man-made island nearby, called Semakau island. Geddie (2018) reported that Semakau Island, Singapore’s only landfill, is expected to be filled up by 2035. Originally, Semakau island was expected to last till 2045. However, due to the amount of waste generated that has increased over the years, the projected lifespan of the landfill was shortened. Thus, we should play a part and contribute more to protect the environment. Initiatives must be taken to reduce plastic production and consumption to provide a better future for the next generation.

Developed cities such as South Korea had imposed certain types of disposable plastic ban (Armstrong, 2019). One such example, from the same article, is plastics that are only used for “wet” items such as fish and meat. Singapore can similarly protect the environment by reducing unnecessary plastic consumption in the form of bottles and beverage packaging.

The role of preventing more plastics from being produced also lies in the daily activities of a person. One of the main culprits for the extensive amount of plastic used can be attributed to F&B businesses. To address the issue of plastic waste in Singapore, SIT can play a part by ensuring that F&B operators will take measures to reduce plastic packaging. 

As SIT Punggol is designed to be an integrated campus where it “integrates applied research and innovation”, the team has decided to use the upcoming SIT Punggol as a testbed before recommending this proposal to other beverages stalls in Singapore. As it is surrounded by the Punggol community and business park, this will allow for integration which would generate opportunities for students and industry professionals to work on projects together that can contribute back to the community (SIT, 2019). 

1.1 Current situations in Singapore

Incineration of trash was introduced to Singapore in 1978 in the form of Waste-to-energy (WTE) plants. Currently, incineration helps prolong the lifespan of the landfill by reducing the amount of volume of waste. According to the Ministry of the Environment and Water Resources (MEWR), incineration of plastic can reduce the total volume from 100% to 10%. But it is not a viable long term solution as the burning of plastic will release fumes that are hazardous to the environment. Without incineration of this non-biodegradable material, it would stay around for generations. 

In 2007, the National Environment Agency (NEA) had started the Singapore Packing Agreement (SPA). In this voluntary agreement, NEA and operators worked together to reduce “packaging wastage” from innovative design, efficient manufacturing and encouraged “reuse or recycling of packaging materials”. According to NEA (2019), under the second SPA’s duration, businesses have reduced the total amount of 54,000 tonnes of packaging waste.

ZeroWaste SG (2018) has also published a guide to encourage food and beverage (F&B) operators to reduce plastic usage. In this guide, auditors issued a rating for popular F&B operators based on efforts in reducing plastic usage, persuade consumers to adopt a Bring Your Own (BYO) culture and suggest other things for them to contribute more. The results published in this guide show that the majority of F&B operators are open to the concept of a BYO culture.

The ideal situation would be for stores selling beverages under the Singapore Food Agency (SFA), should not use plastic cups for their drinks. The SFA should include regulations for the shops to omit plastic for their cups, straws, and carriers. 

1.2 Problem statement

The amount of plastic waste contributed by beverages consumption is high due to the extensive amount of usage of single-use plastics. This poses plastic pollution threat to the ocean which would, in turn, contribute to climate change.

1.3 Purpose statement

The purpose of this proposal is to provide feasible solutions to reduce plastic usage from beverage stalls in Singapore. This is to ensure that Singapore’s plastic waste situation can be alleviated. In addition, the upcoming Punggol campus can adopt this system to test for the feasibility of the idea island-wide.

2. Proposed solutions 

The team took reference from the data generated from the survey (Refer to Appendix C) and researched the current happenings in other countries and found that some of the solutions can also be applied in the context of Singapore, making use of the upcoming SIT Punggol as a trial before recommending to implement the solution islandwide. With the help of SFA to administer guidelines, this solution could be executed to encourage the reduced use of plastic packaging for beverages. 

2.1 Dispenser-Type Beverages

PepsiCo (2019) has launched a new “hydration platform” in the form of a smart dispenser. (Refer to Appendix A) The consumer will bring their own bottle/container to the smart dispenser, then the dispenser will scan the consumer’s unique QR code and dispense according to the consumer’s choice. As the smart dispenser system uses QR code, it will remember the consumer’s preferences. It will also automatically track the daily consumption of fluids by the number of refills and the reduced “environmental impacts” by using the system. 

Unlike PepsiCo where they adopt a smart system for dispensing drinks, there is another type of dispenser in the market that utilizes a similar idea as PepsiCo but it is more applicable for traditional hand made drinks. In one of NUS’s canteens, there are dispensers for common drinks like hot coffee and tea. (Refer to Appendix B) The drinks operator will make the drink in bulk, then they will put it in the dispenser and consumers will fill their cups with their preferred drinks after paying for it. The use of such dispensers for beverages in stores can help to reduce stress on Singapore’s plastic problem by encouraging consumers to use their own containers and reduce the need for unnecessary packaging.

2.2 Rental cups

Currently, beverage stalls normally provide a plastic cup when a consumer makes a purchase. This ‘rental cups’ method is a new service introduced in Singapore by a company ‘Revolv’ with the aim to cut out single-use plastics for takeaways. How this system works is when a customer buys a cup of coffee to go, he/she will pay a deposit amount on top of the price of the beverage. Customers will get their deposit back when they return the cup at another participating outlet, and no washing is required.
Mahmud (2019) stated that “A new service recently launched in Singapore wants to replace single-use plastic in takeaways with reusable cups and containers that customers can rent technically for free.” With such service availability, consumers do not need to bring their own cup and are still reducing the use of plastic. 

2.3  Using sustainable material as alternative

2.3.1 Glass (for bottles)

Glass bottles could be an alternative material for bottled drinks. 
Based on one of the group member’s experience, the restaurant she worked at previously reused all the chilli bottles instead of throwing them away and replacing them with new ones. Every night, there will be a staff assigned to wash the chilli bottles that were almost empty and would then refill with a new batch of chilli from the can. 

2.3.2 Stainless steel (for straws)
F&B businesses have started to phase out plastic straws in the effort to reduce plastic waste. Fast food companies such as Burger King and KFC have stopped providing customers with plastic straws unless there is a request for it. The usefulness of the straw would only last as long as the drink, after which it will be treated as trash. Hence, reusable straws will ensure that people are able to consume their drinks without causing pollution. One such material that can be used to make these reusable straws are stainless steel.     

3. Benefits proposed solutions

3.1 Dispenser for Beverages 

The use of dispensers allows people to store their preferred choice of beverage in their own bottles or cups. This reduces the need for plastic bottles to be manufactured which will eliminate the additional cost and in turn, increase the savings for businesses. 

Beverages that are normally bottled can be replaced by the dispenser. This will not only cut down the plastic bottle usage but also to help the consumer to pick up a habit of bringing their own cup or bottle all the time. Such dispensers allow better efficiency because customers will no longer require another person to get the drinks for them. 

3.2 Rental Cups/containers

Rental cups/containers allow customers to patronize stores that only provide disposables takeaway without producing packaging wastage. This is good as the savings on the packaging can be utilized elsewhere. Also, the reduced hassle for consumers to bring their own cups/containers will encourage consumers to participate. 

3.3 Using sustainable material       

Glass bottles can be reused and recycled, this creates an ecosystem where glass can be used multiple times and provide convenience to users at the same time. Opting for glass as a replacement would be feasible as there are many benefits it brings. According to the Glass Packaging Institute (GPI) (2015), glass bottles and containers are 100% recyclable and can be continuously reused without the loss of purity or value and for each ton of recycled glass, over a ton of natural resources are saved. GPI also mentioned that up to 95% of the raw materials are replaced with recycled glass and manufactures will be able to benefits from recycling such as decreases raw material emissions and use, extends the life of plant equipment, such as furnaces, and saves energy.

Steel is a metal that can be used to make cups and straws respectively. The material is known to be durable and can last a long time in terms of wear and tear. Thus, the use of steel straws can reduce the need for manufacturing plastic for beverages in the long term. 

4. Limitations of proposed solutions 

Apart from benefits, the solutions we provided has drawbacks as well. This way, our stakeholders will be able to weigh the pros and cons of each solution and decide which solution to put into practice. 

4.1 Dispenser for Beverages
It is only limited to homemade drinks such as milo and coffee. This might also lead to an uneven mixture over a period of time and difficulties in maintaining the temperature. A consumer might abuse it by taking more than what they paid for. The last challenge that will be faced is what will occur when the dispenser is empty. 

As compared to noncarbonated drinks, carbonated drinks require a carbon dioxide tank (CO2 tank) to produce the carbonated effect. Additional human resources will then be required to replace the CO2 tank.

4.2 Rental Cups
The system of having cups and containers for rent requires huge logistic work. Furthermore, it relies heavily on users to follow the practices. Customers might not be able to return the item on time and in good condition. As this system is currently not implemented widely, users might not be able to have access to the system. This makes it inconvenient for visitors to make a trip to return the item. Also, the system might be prone to abuse as people might not treat the items with care and will result in problems such as damaged cups and not returning the cups on time.

4.3 Sustainable material as an alternative
While glass is superior in terms of its carbon footprint, there are some disadvantages that make plastic more preferable than glass. Weight and fragility are some drawbacks. Glass generally weighs heavier than plastic which means more trips are required when transporting packaged goods which would lead to a great impact on the environment. Also, glass has the tendency of breaking easily. This means if a glass bottle is knocked over, it would leave a mess behind and it would be dangerous due to the small fragments.

Given that stainless steel is a good conductor of heat, the straws made from stainless steel cannot be used for hot drinks. Since straws are long in nature, when washing, it will be hard to reach the inner side of the middle straw segment thus leading to hygiene issues.

5. Evaluation

After much deliberation on the benefits and limitations of all three solutions, the team has decided that having a system where consumers can use their personal bottle to collect their drinks from the dispenser will be the most suitable option to counter the high use of plastic packaging.

With the implementation of this system, the amount of plastic packaging required for pre-packed drinks and instant takeaway beverages will be reduced as consumers will have to use their own bottles. This system, compared to the use of alternate materials, will be more suitable because it does not require a huge amount of investment and the campus can be set up as an ideal testbed for this system. 

The system, however, has its limitations. Customers who do not have a bottle in hand might not be able to proceed in making their purchase. Hence, we have thought of the integration of a rental cup system, similar to Revolv’s, which will allow people to have a choice of renting a cup. This would allow people to enjoy their drinks while eliminating the need for businesses to supply disposable cups in the event if the consumers do not have their bottles with them and reusable cups are also not available. 

6. Methodology

This section illustrates the methods used by the team to gather information for the report.

6.1 Primary Research
The team conducted a survey to find out what are people’s thoughts of owning a reusable straw or cup.

Through this survey, the team was able to get first-hand data on the percentage of people who own reusable straw or cup and the reasons why they do not own them. Also, we were able to find out the reasons behind people’s unwillingness to bring out their own reusable straw or cup although they do own one. 

The data collected is useful for us to come up with a solution that would cater to the opinions provided.

6.2 Secondary Research

Each of the team members did research to retrieve statistics of the amount of plastic waste over the past few years, benefits, and solutions to limitations. The majority of the research was extracted from trustable news articles or journals. Through the research process, the team has also gained an initial insight into the research problem. 

7. Conclusion

The team believes that with a dispenser integrated with the rental cup system, the need for plastic for packaging will decrease. This is because it removes the unnecessary packaging step from the traditional manufacturing chain in beverage production. With the Punggol campus built by 2021, it can be used as a testbed in line with the goals of the Zero waste master plan. 

After which, SFA could implement this protocol for beverage stalls at other educational institutes. In the long run, perhaps SFA can introduce it across the beverage industry to combat the plastic waste issue in Singapore.

Technical report_Draft 2


2. Proposed solutions 

The team researched the current happenings in other countries and found that some of the solutions can also be applied in the context of Singapore to encourage the reduced use of plastic as a material for beverages. 

2.1 Dispenser-Type Beverages

2.1.1 Dispenser for packaged drinks
Evian (2019) has officially revealed their new product called “Evian (re)new”. This new product is a dispenser-styled “water appliance” that dispense water designed for home use. It contains a 5-litre water container that will sag after water is dispensed.  This new design is notable as the water container is made with “100% recycled plastic” and can be totally recycled. When compared to the traditional 1.5-litre water bottle also made by Evian, it uses two-thirds lesser plastic to produce.

PepsiCo (2019) has launched a new “hydration platform” in the form of a smart dispenser. The consumer will bring their own bottle/container to the smart dispenser, then the dispenser will scan the consumer’s unique QR code and dispense according to the consumer’s choice. As the smart dispenser system uses QR code, it will remember the consumer’s preferences. It will also automatically track the daily consumption of fluids by the number of refills and the reduced “environmental impacts” by using the system. 

In Singapore, there is no such initiative currently. As such, the team recommends Singapore to adopt this for research of feasibility.


2.1.2 Dispenser for Hawker Centre-styled setting 

In some of Singapore’s hawker centre, there exist dispensers for common drinks like hot coffee and tea. The drinks operator will make the drink in bulk, then they will put it in the dispenser and consumers fill their own cup whenever they want to. The use of such dispensers for beverages in stores can help to reduce stress on Singapore’s plastic problem by encouraging consumers to use their own containers and reduce the need for unnecessary packaging.


2.2 Rental cups

The current beverage stalls normally provide a plastic cup when a consumer makes a purchase. Mahmud (2019) stated that “A new service recently launched in Singapore wants to replace single-use plastic in takeaways with reusable cups and containers that customers can rent technically for free.” With such service availability, consumers do not need to bring their own cup and are still reducing the use of plastic.

2.3  Using sustainable material as alternative

2.3.1 Glass (for bottles)

Glass bottles could be an alternative material for bottled drinks. Opting for glass as a replacement would be feasible as there are many benefits it brings. Firstly, glass is fully recyclable and can be recycled endlessly without degrading its value. Next, a massive amount of natural resources are saved for every ton of glass that is recycled. Lastly, recycled glass is substituted for up to 95% of raw materials. 

According to one of our group mate’s experience, the restaurant she worked at previously reused all the chilli bottles instead of throwing them away and replacing them with new ones. Every night, there will be a staff assigned to wash the chilli bottles that were almost empty and would then refill with a new batch of chilli from the can.

2.3.2 Stainless steel (for straw)
Stainless steel is versatile yet one of the most environmentally friendly materials. Stainless steel is corrosion-resistant, durable, have high-recycled content and recapture rates, provides long service life and reduces resource use. Even if stainless steels are not recycled, they would not have any damaging effects on the soil or groundwater of the landfill.



3. Benefits proposed solutions

3.1 Dispenser-Type Beverages 
The use of dispensers encourages people to store their favourite beverage in their own bottles. It reduces the need for plastic bottles to be manufactured for the beverages. Also, plastic bottles and cups’ usage will decrease, hence providing savings for businesses. 

Beverages that normally comes in bottle form can now switch to syrup form and install in the dispenser. This will not only cut down the plastic bottle usage and also help the consumer to have a good habit of bringing their own cup all the time. Such dispensers allow better efficiency because customers will no longer require another person to get the drinks for them. 

3.2 Rental Cups/containers

Rental cups/containers allow customers to patronise stores that only provide disposables takeaway without producing packaging wastage. This is good as the savings on the packaging can be utilized elsewhere. Also, reduce the hassle for consumers to bring their own cups/containers which encourages the consumers’ participation. 

3.3 Using sustainable material       

Glass bottles can be reused and recycled, this creates an ecosystem where glass can be used multiple times and provide convenience to users at the same time. The amount of energy used by reusing a glass bottle is lesser than recycling plastic waste, which makes it more environmentally friendly.

Aluminium and steel are metals that can be used to make cups and straws respectively. Metals are known to be durable and can last a long time in terms of wear and tear. Thus, the use of aluminium cans and steel straws can reduce the need for manufacturing plastic for beverages in the long term. 

4. Limitations of proposed solutions 

4.1 Dispenser-Type Beverages
In today’s throw-away culture, such practice of utilizing our own bottles for beverages is uncommon. Thus it might be a hassle for consumers to bring their own bottles if they do not have the habit of doing so. Evian Re(new) adopts the same way as to how a normal water cooler dispenser works where the water is replaced per container. However, the container is not easily purchasable, unlike the water cooler dispenser where there are many different companies to purchase from. 

It is only limited to homemade drinks such as milo and coffee. This might also lead to uneven mixture over a period of time and difficulties in maintaining the temperature. A consumer might abuse the rule by taking more than what they paid for. The last challenge that will be faced is the ability to tell whether it is empty. 

As compared to noncarbonated drinks, carbonated drinks require a carbon dioxide tank (CO2 tank) to produce the carbonated effect. A CO2 tank that contains 31kg of carbon dioxide can last up to 3 months depending on usage. This will also require additional manpower to replace the CO2 tank.

4.2 Rental Cups
The system of having cups and containers for rent requires huge logistic work. Furthermore, it relies heavily on users to follow the practices. Customers might not be able to return the item on time and in good condition. As this system is currently not implemented widely, users might not be able to have access to the system. This makes it inconvenient for visitors to make a trip to return the item.

Also, the system is prone to abuse, people might not treat the items with care and will result in problems such as the lack of proper sanitation which might cause other users to suffer from food-related illness.

4.3 Sustainable material as an alternative
Even though glass is superior in terms of the amount of carbon footprint it leaves behind, there are some drawbacks that make plastic more preferable as compared to glass. Some drawbacks are weight and fragility. Glass generally weighs heavier than plastic which means more trips are required when transporting packaged goods which would lead to larger environmental impact. To add on, glass has the tendency of breaking easily. This means if a glass bottle is knocked over, it would leave a mess behind and it would be dangerous due to the small fragments.

Since stainless steel, it is a good conductor to heat, the straws made from stainless steel cannot be used for hot drinks. Also, stainless steel straws might pose a hygiene problem if it is not cleaned properly. As straws are long in nature, it will be difficult to reach the inner side of the middle section of straw when washing.
