Whilst many advances are still being made in the bio-based industry we must not ignore the reality that some bioplastics don't perform as well and if not better than traditional based plastic on both performance and cost. One company dedicated to change this is the American based Green Dot Bioplastic company. They are researching extensively to deliver a bioplastic which meets consumer expectations and put an end to our war with plastic. For years, Green Dot has worked with plastic manufacturers and product designers to make products to help consumers contribute to a more sustainable world. Now the bio-based producer has revealed that they will now offer a line of biocomposites combining natural fibres and Braskem’s I’m Green Polyethylene. Biocomposite plastics combine natural fibres or wood flour with recycled, biodegradable or biobased plastic. Green Dot are now introducing their terratek biocomposites made with more than 90 percent of renewable feedstock.
Terratek Biocomposites are designed to meet the rapidly growing consumer demand for more sustainable plastic products. They can be produced using a variety of natural fibres and agricultural by-products including wood, corn cob, hemp or wheat stalk. Custom formulations can be developed to meet the specific value propositions for a product or market segment.
Terratek Biocomposites combines these natural fibres with Braskem’s ( @BraskemBio ) I’m Green Polyethylene (PE) to create a strong, durable biocomposite. It can deliver a wide range of physical characteristics with a lighter environmental footprint compared to petroleum-based plastics. The natural fibres provide strength and durability to the plastic and add a unique natural aesthetic to enhance product differentiation.
The bio-based I’m Green PE from Braskem is made from ethanol – a renewable and sustainable resource produced from Brazilian sugarcane. Alongside this, the cultivation of sugarcane removes carbon dioxide from the atmosphere and releases oxygen, which means the material has a negative carbon footprint. I’m Green PE took years of dedicated research and development, and in 2010, Braskem began producing I’m Green on a commercial scale.
Green Dot ( @gd_bioresins ) produces Terratek Biocomposites at its Kansas plant where pellets are optimised for injection moulding, profile or sheet extrusion.
Green Dot’s Terratek Biocomposites open a wide range of new possibilities for bio-based plastics, enhancing physical properties while lightening the environmental footprint of the products everyone uses every day.
So what are the bio-based alternatives to plastic?
Renewable Feedstock: Organic materials like starch and other natural fibres act as substitutes for petroleum-based feedstock and reduce the amount greenhouse gas emissions associated with plastic production. Bio-based plastic resins can be made to behave similarly to traditional plastics in the manufacturing phase and to preserve much of the look and feel of purely petroleum-based plastics.
Reclaimed feedstock: Wood fibers from milling operations and agricultural waste materials can also be used to substitute out some of the petroleum-based feedstock that goes into traditional plastics. In some cases, up to 70 percent of non-renewable resources can be replaced. With widespread use, reclaimed feedstock could make a serious dent in the amount of fossil fuels used by the global plastics industry.
Biodegradable materials: Compostable plastics can help reduce landfill waste, especially when used for food service in conjunction with composting of food waste, and in many packaging applications. In some cases, such as mulch films, biodegradability provides products with a functional advantage.
