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.
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.
In the 1980s and 1990s, plastic recycling and the development of biodegradable plastics began to flourish to mitigate environmental impacts. [139] [140] From 2000 to the present, bioplastics from renewable sources and awareness of microplastics have spurred extensive research and policies to control plastic pollution. [141]
A plastic is considered biodegradable if it can degrade into water, carbon dioxide, and biomass in a given time frame (dependent on different standards). Thus, the terms are not synonymous. Not all bioplastics are biodegradable. [44] An example of a non-biodegradable bioplastic is bio-based PET. PET is a petrochemical plastic, derived from ...
As an example, the mixture of THFA with FAME and ethyl lactate has been patented as a paint stripper. [61] Ionic liquids particularly have applications in electrodeposition. [62] Their relevance as green solvents is further enhanced by the emergence of production methods based on renewable and biodegradable resources. [63]
From bio-inspired concrete that heals itself like living organisms to biodegradable alternatives that reduce waste, examples of biomimicry in sustainable building materials are reshaping the ...
The global production of CA materials was over 800,000 tonnes (790,000 long tons; 880,000 short tons) per year in 2008. While it was initially believed that CA was virtually non-biodegradable, it has been shown that after initial partial deacetylation, the polymer's cellulose backbone is readily biodegraded by cellulase enzymes.
An example of a compostable polymer is PLA film under 20μm thick: films which are thicker than that do not qualify as compostable, even though they are "biodegradable". [14] In Europe there is a home composting standard and associated logo that enables consumers to identify and dispose of packaging in their compost heap.
