Plastic pollution is a pressing issue, with plastic waste accumulating in oceans, rivers, and even the Arctic sea ice. While plastic is useful in modern life, its production and disposal contribute to greenhouse gas emissions and hazardous waste. The main solution lies in reducing plastic usage, but innovative approaches are also emerging. These include converting plastic waste into roads, using bioplastics made from renewable biomass, and developing technologies to improve recycling methods and break down plastics. Collaborative efforts, such as the Global Plastics Treaty, are also underway to address the lifecycle of plastics and mitigate their environmental impact.

Reduce plastic production
To reduce plastic production, it is important to focus on reducing plastic waste and promoting sustainable alternatives. Here are some ways to achieve this:
Encourage Reusable Options: Promote the use of reusable items instead of single-use plastics. This includes reusable water bottles, tumblers, bags, containers, and cutlery. Consumers can be incentivized to bring their own reusable items when shopping or dining out, reducing the demand for single-use plastic packaging and utensils.
Reduce, Reuse, and Recycle: Educate individuals about responsible waste management practices. Encourage reducing plastic consumption, reusing plastic items whenever possible, and recycling or properly disposing of plastic waste. Individuals can opt for products with minimal packaging and choose items made from recycled plastic materials.
Support Sustainable Alternatives: Encourage the development and use of sustainable alternatives to traditional plastics. This includes bioplastics made from renewable biomass sources, such as seaweed or vegetable fats and oils. These alternatives are biodegradable and can be used for packaging materials, reducing the environmental impact of plastic production.
Innovative Waste Management: Implement innovative solutions to manage plastic waste effectively. This includes technologies like the Catalytic Hydrothermal Reactor (Cat-HTR), which can convert unrecyclable plastic into oil or other usable materials. Additionally, projects like PlasticRoad utilize recycled plastic to create durable roads, reducing the need for asphalt and diverting plastic waste from landfills.
Corporate Responsibility: Encourage companies to take responsibility for their plastic packaging. Consumers can provide feedback to companies, expressing their concerns about non-recyclable packaging. Companies can work on improving the recyclability of their packaging and developing eco-friendly alternatives.
By implementing these strategies, we can significantly reduce plastic production by minimizing waste, promoting reusable options, supporting sustainable alternatives, and advocating for innovative waste management solutions.

Use bioplastics
Bioplastics are an alternative to traditional plastics, made from renewable biomass sources such as vegetable fats and oils, cassava starch, woodchips, food waste, and even seaweed. They are often made from plant material such as corn, sugar beets, or potato starch. Bioplastics are compostable and can be engineered to fully decompose under certain conditions, typically in an industrial composting facility.
One example of a company utilising bioplastics is Evoware, an Indonesian start-up that works with local seaweed farmers to create sandwich and burger wraps, sachets, and soap packaging. This packaging can be dissolved in hot water or, in some cases, is edible. Another company, Full Cycle Bioplastics in California, produces PHA from organic waste, including food waste, crop residue, and garden waste. Their bioplastic is compostable, marine degradable, and has no toxic effects.
Bioplastics have been promoted as a solution to plastic pollution, with companies like Coca-Cola and Pepsi under public pressure to address this issue. Coca-Cola's PlantBottle, for instance, is a new kind of recyclable plastic container, 30% of which is made from sugar cane and other plants. However, despite the growing push for organic plastic, creating bioplastics that are both cheap and effective has been challenging. Bioplastics often compete with food production for land, and the process of converting plant material into plastic building blocks can be expensive. Additionally, bioplastics may not fully decompose as expected and can end up as litter, causing harm to marine life.
While bioplastics may not be a perfect solution, they are part of a broader strategy to combat plastic pollution. The Pew report, for instance, recommends a $600 billion overhaul of the global plastic system, including the reuse and recycling of plastic in a circular economy, alongside smaller-scale changes like the use of bioplastics.

Improve waste management
Improving waste management is a critical aspect of tackling the plastic waste problem. Here are some measures that can be implemented to enhance waste management systems:
Firstly, it is essential to reduce plastic waste generation by encouraging the use of alternative materials and promoting reusable options. This involves supporting innovations like bioplastics, which are made from renewable biomass sources such as vegetable fats and oils, cassava starch, woodchips, or food waste. For example, Evoware, an Indonesian start-up, uses seaweed to create packaging that can be dissolved in hot water or even safely ingested. By embracing these eco-friendly alternatives, we can minimize the volume of plastic waste entering our waste management systems.
Secondly, waste management infrastructure needs to be improved, especially in less wealthy countries. Currently, a significant portion of plastic waste is not collected, leading to improper disposal methods such as open burning, which releases toxic chemicals into the atmosphere. Investing in waste collection systems and ensuring access to proper waste management facilities can help address this issue. Additionally, implementing waste sorting and separation techniques can improve the efficiency of recycling processes.
Thirdly, recycling technologies and processes need to be enhanced. While recycling is a crucial part of waste management, it is important to recognize that not all plastics are currently recyclable. Advancements in technology, such as the development of solvents to separate multilayer packaging, can improve the recyclability of certain plastics. Additionally, technologies like the Catalytic Hydrothermal Reactor (Cat-HTR) can convert unrecyclable plastic into oil or liquid fuel, offering a unique solution to plastic waste.
Lastly, waste management policies and strategies should be implemented at a national and global level. The "National Strategy to Prevent Plastic Pollution" in the US, for instance, aims to reduce plastic pollution through a series of interventions. Similarly, the Global Plastics Treaty, currently under negotiation, seeks to address the entire lifecycle of plastics. These strategies provide a framework for governments and organizations to take action and drive systemic change in waste management.
By adopting these measures, we can improve waste management systems, reduce plastic waste, and mitigate the environmental and health impacts associated with plastic pollution.

Develop plastic-degrading agents
Plastic waste is a pressing issue, with plastic taking hundreds of years to degrade and leaching toxic chemicals into the environment in the process. The development of plastic-degrading agents is a promising solution to this problem.
One approach is to use microorganisms and microbes with a two-enzyme system. For example, the I. sakaiensis strain has a dual enzyme system containing PETase and MHETase, which can break down crystalline polyester substrates. Scientists have genetically engineered these enzymes to improve their degradation efficiency, allowing bacteria to degrade 90% of plastic products within 10 hours.
Another example of a plastic-degrading agent is the fungus Aspergillus tubingensis, which can degrade polyurethane (PU). This discovery was made by a group of microbiologists at Quaid-i-Azam University in Pakistan.
In addition to biological agents, there are also technological solutions. Australian company Licella Holdings has developed a patented technology called the Catalytic Hydrothermal Reactor (Cat-HTR). This technology can convert unrecyclable plastic into oil by melting it down and reducing it to its component parts. The process is similar to using a commercial-sized pressure cooker and produces materials such as oils, waxes, and plastics that can be turned into other products or fuels.
The development of plastic-degrading agents shows promise in addressing the plastic waste problem. By breaking down plastics, these agents have the potential to reduce the environmental and health impacts of plastic pollution.
