Disposable plastic cups made from biodegradable plastic. Biodegradable plastics are plastics that can be decomposed by the action of living organisms, usually microbes, into water, carbon dioxide, and biomass. [1] Biodegradable plastics are commonly produced with renewable raw materials, micro-organisms, petrochemicals, or combinations of all ...
Boxed products made from bioplastics and other biodegradable plastics. Few commercial applications exist for bioplastics. Cost and performance remain problematic. Typical is the example of Italy, where biodegradable plastic bags are compulsory for shoppers since 2011 with the introduction of a specific law. [16]
The first catgut sutures were made from the intestines of sheep, but modern catgut sutures are made from purified collagen extracted from the small intestines of cattle, sheep, or goats. [5] The concept of synthetic biodegradable plastics and polymers was first introduced in the 1980s. [6]
Manuel Rendon (born in San Cristobal, Venezuela, 1987) is an inventor and engineer who created a U.S. patented formulation for the dynamic disintegration of plastics, the upcycling process for unsorted waste stream and a bio-based copolymer with programmable water solubility.
The world's first fully synthetic plastic was Bakelite, invented in New York in 1907, by Leo Baekeland, [5] who coined the term "plastics". [6] Dozens of different types of plastics are produced today, such as polyethylene , which is widely used in product packaging , and polyvinyl chloride (PVC), used in construction and pipes because of its ...
Most bags that are manufactured from plastic are made from corn-based materials, like polylactic acid blends. Biodegradable plastic bags are nowadays as strong and reliable as traditional (mostly polyethylene)-bags. Many bags are also made from paper, organic materials like Manila hemp, or polycaprolactone.

These tiny plastic particles choke wildlife, disrupt ecosystems, and threaten human health – and they are notoriously difficult to remove. ... a biodegradable sponge made of squid bones and ...
Parkesine, the first member of the Celluloid class of compounds and considered the first man-made plastic, is patented by Alexander Parkes. [4] 1869: John Wesley Hyatt discovers a method to simplify the production of celluloid, making industrial production possible. 1872: PVC was accidentally synthesized in 1872 by German chemist Eugen Baumann ...
