When it comes to sustainability, the plastic you choose to use will have a significant impact on the environment. This is because the majority of plastic ends up in landfills.
However, you can take steps to reduce your waste by choosing products that are made from renewable materials. You can also carry reusable cloth bags and avoid single-use plastics.
A growing number of products are being designed using recycled materials. These new designs can help decrease the energy used in manufacturing and transportation and may help slow the global rate of plastic pollution.
Many of the products are made from natural polymers, such as starch, lignin, and cellulose. These materials are commonly found in the stem walls of plants.
Starch is a biodegradable material, but it isn’t as durable as other plastics. For example, it is often not a suitable substitute for bottles and packaging.
Plastics made from cellulose, starch, or lignin can be composted, which can reduce landfill waste. The material is used in many applications, including food containers, medical equipment, and food contact products.
One plastic that is starting to gain traction is poly(diketoenamine). PDK, which is chemically similar to cellulose, is a new type of biodegradable plastic that is quickly breaking down in landfills. It won’t lose quality when recycled, and will be less expensive as it becomes commercially viable.
Some experts believe that PDK-based plastic will quickly become as sustainable as other conventional plastics. According to a study by Science Advances, a commercial-scale PDK recycling pipeline is possible.
