Braskem is the world leader in the production of biopolymer, with the Green Polyethylene "I'm green™", a thermoplastic resin produced from ethylene made from sugarcane ethanol, a 100% renewable raw material which helps reduce greenhouse gas emissions. The production started in 2010 and is located in Triunfo, South of Brazil.
A bioplastic such as high-density polyethylene (HDPE) [113] can be 100% biobased (i.e. contain 100% renewable carbon), yet be non-biodegradable. These bioplastics such as HDPE nonetheless play an important role in greenhouse gas abatement, particularly when they are combusted for energy production.

Polyethylene was first synthesized by the German chemist Hans von Pechmann, who prepared it by accident in 1898 while investigating diazomethane. [12] [a] [13] [b] When his colleagues Eugen Bamberger and Friedrich Tschirner characterized the white, waxy substance that he had created, they recognized that it contained long −CH 2 − chains and termed it polymethylene.
The project, announced in October, is integrating multiple homegrown agritech solutions, including SecondSky, to grow crops such as tomatoes, cucumbers, peppers and herbs, supplied to Red Sea ...
For instance, "manufacturing of PHAs by fermentation in Brazil enjoys a favorable energy consumption scheme where bagasse is used as source of renewable energy." [69] Many biodegradable polymers that come from renewable resources (i.e. starch-based, PHA, PLA) also compete with food production, as the primary feedstock is currently corn. For the ...
Biopolymers can be sustainable, carbon neutral and are always renewable, because they are made from plant or animal materials which can be grown indefinitely. Since these materials come from agricultural crops, their use could create a sustainable industry. In contrast, the feedstocks for polymers derived from petrochemicals will eventually ...
Starch is a renewable and cheap resource that is available all year round, making it a viable biodegradable additive. [ 1 ] Starch can be converted into plastic pellets that can then be used as a biodegradable additive to other plastics, such as polyethylene.
