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]
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 ...
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]
Oceans often act as renewable resources. Sawmill near Fügen, Zillertal, Austria Global vegetation. A renewable resource (also known as a flow resource [note 1] [1]) is a natural resource which will replenish to replace the portion depleted by usage and consumption, either through natural reproduction or other recurring processes in a finite amount of time in a human time scale.
Examples of emerging bioproducts or biobased products include biofuels, bioenergy, starch-based and cellulose-based ethanol, bio-based adhesives, biochemicals, bioplastics, etc. [8] [9] Emerging bioproducts are active subjects of research and development, and these efforts have developed significantly since the turn of the 20/21st century, in ...
