Traditionally, plastics have been derived from fossil fuels, raising concerns about their environmental impact. Bioplastics, emerging as a sustainable alternative, are capturing the world’s attention. But how are these nature-based plastics actually made? Let’s delve into the fascinating bioplastic manufacturing process.
Step 1: Sourcing the Feedstock
The journey begins with selecting the raw materials. Unlike petroleum-based plastics, bioplastics utilize renewable resources like –
- Starch: Extracted from corn, potatoes, or cassava, starch forms the backbone of many bioplastics, particularly Polylactic Acid (PLA).
- Cellulose: Found in abundant biomass like wood pulp or agricultural waste, cellulose offers structural strength to bioplastics.
- Sugars: Derived from crops like sugarcane or sugar beet, sugars feed the fermentation process in certain bioplastic production methods.
- Microorganisms: Bacteria and fungi can be used to produce biopolymers directly, called Polyhydroxyalkanoates (PHAs).
Biome Technologies plc (LON:BIOM) is a growth oriented, commercially driven technology group. The Group’s primary activity is the development of its fast growing business in bioplastics. The Group comprises two divisions: Biome Bioplastics and Stanelco RF Technologies.
