The Starbucks Plan to Minimize Waste

The Starbucks Plan to Minimize Waste

In 2022, Starbucks announced a company goal to reduce waste sent to landfills from stores and direct operations. The goal was to reduce waste by 50% by 2030. Part of Starbucks plan to minimize waste is to move away from single-use plastics and promote reusability to shift towards a circular economy. It is said that 40 percent of Starbucks’ annual packaging is attributed to disposable cups. Moreover, these cups account for 20 percent of its waste footprint.

The Starbucks plan to minimize waste focusses on reducing its environmental impact; the coffee company hopes to create a cultural movement towards reusables by giving customers easy access to personal or Starbucks-provided reusable to-go cups that can be used in their cafes, drive-thrus, and mobile order and pay.

The Starbucks plan to minimize waste includes several reusable programs to help achieve its goals. They have been testing these programs in phases since 2022. Their Borrow a Cup program allows customers to order their drink in a designated Starbucks reusable cup. The cups are designed to be returned to the stores after use, professionally cleaned, and then reused by other customers. This project is being tested in Seattle, Japan, Singapore, and London.

In 2022, Starbucks implemented 100% reusable operating models, eliminating single-use cups completely. They tested this in 12 stores in Seoul, which helped to divert more than 200,000 disposable cups from the landfill. In early 2023, Starbucks tested their 100% reusables operating models at stores at Arizona State University. They also implemented return bins across the campus near garbage and recycling bins to collect the borrowed cups.

The Personal Cups & For-Here-Ware initiative encourages customers to bring their own cups. Starbucks began testing this initiative at their experiential Greener Store in Shanghai. Furthermore, Starbucks has been developing ways to incentivize customers to bring their own cups. This includes offering free coffee or discounts to customers who bring their own cups. They’ve also partnered with the Ocean Conservancy to donate 1$ to the organization if customers bring in their clean, reusable cups. At their Arizona State University campus stores and cafes in O’ahu, Hawaii, they have started implementing washing stations so customers can have their cups cleaned before ordering their beverage.

Because disposable cups are still in circulation, Starbucks is looking at ways to make the cups more sustainable and out of better materials. They are working on doubling the hot cup recycled content and reducing the materials required to make the cup and liner. The paper used for their hot cups will be sustainably sourced and certified by the Forest Stewardship Council. Over $5 million has been invested to develop a more sustainable hot cup. By the end of 2023, Starbucks will have eliminated PFAS from all of their packaging. Starbucks has already switched from plastic straws to compostable ones in stores across the globe.

The Starbucks plan to minimize waste is still in the trial phases of its programs. It needs to address a few concerns, including the best ways to collect and wash the cups and especially to figure out the best ways to encourage bringing the reusable cups back and not simply throwing them away. Moreover, they need to figure out how to make the lids of their hot cups recyclable and compostable and to encourage people to throw the contents in the right places.

It is encouraging to see a big company like Starbucks working to reduce waste and be more environmentally friendly in the ways they do business. Hopefully, Starbucks’ plans to minimize waste will influence more coffee shops around the world tol follow suit and help us reduce plastic and disposable cups and promote reusable alternatives.

Eco-Friendly Crab Shell BioPlastic Wrap

Eco-Friendly Crab Shell BioPlastic Wrap

Recently, there has been a growing demand for eco-friendly alternatives to plastic. One promising option is a new type of crab shell bioplastic wrap made from waste grab shells and wood pulp. This new film is flexible, transparent, and can be used to wrap food like plastic wrap. It is also biodegradable and compostable, making it a more sustainable option for food packaging.

Crab Shell BioPlastic Wrap

The new crab shell bioplastic wrap is made by spraying alternating layers of chitin and cellulose fibres sourced from discarded crab shells and wood pulp, respectively, onto a polylactic acid (PLA) base. Chitin is a natural polymer that is found in the exoskeletons of insects and crustaceans. Cellulose is a natural polymer that is found in the cell walls of plants. PLA is a bio-based plastic that is made from renewable resources, such as corn starch.

The new plastic wrap has a number of advantages over traditional plastic wrap. It is made from renewable resources, is biodegradable and compostable, and does not release harmful toxins into the environment. It is also transparent, flexible, and odourless.

The main material that the new plastic wrap is compared to is PET or polyethylene terephthalate. It is one of the most common petroleum-based materials used in transparent packaging, such as vending machines and soft drink bottles. The material showed up to a 67 percent reduction in oxygen permeability compared to some forms of PET. This means that the new plastic wrap could, in theory, keep foods fresher for longer.

In addition to plastic film, PET plastic is used in a variety of applications, including:

  • Bottles: PET is the most common material used for beverage bottles, such as water, soda, and juice. It is also used for some food packaging, such as salad dressing and oil bottles.
  • Fibres: PET is used to make a variety of fibres, including polyester, which is used in clothing, carpets, and other textiles.
  • Films: PET makes various films, including food packaging, insulation, and tapes.
  • Other applications: PET is also used in various other applications, such as electronics, automotive parts, and construction materials.

The new plastic wrap is still in its early stages of development, but it can potentially be a major breakthrough in the fight against plastic pollution. As the technology continues to develop, it is likely to become more widely available and replace traditional plastic wrap in a number of applications.

 

Benefits of Using Crab Shell BioPlastic Wrap:

There are a number of benefits to using crab shell bioplastic wrap. These benefits include:

  • It is made from renewable resources: Eco-friendly plastic wrap is made from renewable resources, such as crab shells and wood pulp. This means that it does not contribute to the depletion of fossil fuels.
  • It is biodegradable and compostable: Eco-friendly plastic wrap is biodegradable and compostable. This means it will not harm the environment when disposed of.
  • It does not release harmful toxins into the environment: Eco-friendly plastic wrap does not release harmful toxins into the environment as it decomposes. This means that it is safe for people and animals.

 

Challenges of Using Crab Shell BioPlastic Wrap:

There are a few challenges to using crab shell bioplastic wrap. These include:

  • It is still in its early stages of development: Eco-friendly plastic wrap is still in its early stages of development. This means that it is not yet as widely available as traditional plastic wrap.
  • It can be more expensive than traditional plastic wrap: Eco-friendly plastic wrap can be more expensive than traditional plastic wrap. This is because it is made from renewable resources and is biodegradable.

Overall, eco-friendly plastic wrap is a promising alternative to traditional plastic wrap. It is made from renewable resources, is biodegradable and compostable, and does not release harmful toxins into the environment. As the technology continues to develop, it is likely to become more widely available and to replace traditional plastic wrap in a number of applications.

Using Light to Convert Lignin into Sustainable Plastic

Using Light to Convert Lignin into Sustainable Plastic

Its biochemical cousin cellulose, a byproduct of the paper and wood milling industry, is well known to many people. But, according to industry analysts, the same procedures generate 50 million tons of lignin each year. 98% of the inky liquid is burnt to create electricity once it has been distilled.

Researchers have been looking for more effective and sustainable methods to turn this naturally occurring polymer into a cleaner and greener building block for use in developing next-generation materials.

According to a new study published in the journal ACS Central Science, scientists at Boston College have created a method for turning lignin into eco-friendly plastics using light.

The scientists then transformed the oligomers into eco-friendly plastics by reacting with crosslinkers, a molecular glue, according to the study. The oligomers produced by the catalyst have distinct chemical structures, allowing the plastics produced in this way to be chemically broken down back into the oligomers and reformed from the oligomers and the crosslinker.

The research advances a viable strategy for the circular plastic economy, a system of waste-free polymer production and reuse, according to the study co-author Dunwei Wang, the Margaret A. and Thomas A. Vanderslice Chair in Chemistry at Boston College.

Wang and Niu, both interested in creating sustainable materials, chose the project based on Wang’s experience in utilizing photocatalysis to induce chemical transformations and Niu’s work of creating recyclable polymers.

Wang added, “The pleasant surprise was the level of controls we were able to exert in decomposing lignin, which is a biopolymer that is notorious for its difficulty to break down. Such a level of control paves the way for downstream applications.”

The study team wants to improve the novel technique for turning lignin into environmentally sustainable plastics that are easy to recycle chemically.

Graduate students Gavin Giardino and Hongyang Wang, along with former post-doctoral researchers Rong Chen and Cangjie Yang, are also co-authors of the study with Niu and Wang.

Compostable plastic cutlery can be recycled into home-insulating foam

Compostable plastic cutlery can be recycled into home-insulating foam

Compostable plastic can be turned into a foam that functions as building insulation, creating a potential solution to difficulties in recycling the material.

Polylactic acid (PLA) is a plastic made of fermented starch from corn or sugar cane. It is designed to break down into harmless material once used and disposed of, but doing so requires industrial composting, which isn’t available in all locations.

If PLA makes its way into the environment, it often won’t break down. Because of this, it is classed as compostable rather than biodegradable by the European Union.

Now, Heon Park at the University of Canterbury in New Zealand and his colleagues have developed a method to convert plastic knives, spoons and forks made from PLA into a foam that can be turned into insulation for walls or flotation devices.

The researchers placed the PLA cutlery into a chamber filled with carbon dioxide. As they increased the pressure inside the chamber, the gas dissolved into the plastic. When they released the pressure, the gas expanded rapidly and turned the plastic into a foam. The process is entirely mechanical and involves no chemical reaction.

“Tweaking temperature and pressure, there is a window where we can make good foams,” says Park. “We found what temperature or what pressure is the best to make those non-foamable plastics into foams.”

Each time plastic is recycled it loses strength, but turning plastic into foam avoids any problems with strength as it is an inherently soft material.

Making PLA plastics directly recyclable in this way could be a better way to alleviate plastic pollution than industrial composting. PLA requires up to 12 weeks of composting at 57°C to break down, and must be carefully separated from other plastic waste, so this may not be the best option.

“If you’ve taken all of the energy and resources to make something, any product or packaging, then the very best thing that you can do with that is to try and keep those resources and turn them back into another item of product or packaging,” says Helen Bird at UK waste and recycling charity WRAP. “From an environmental perspective, if you look at the hierarchy of what’s preferable for the environment, composting actually is a little bit below recycling.”
