Bioplastics are derived from renewable biomass sources like corn starch, sugarcane, and cellulose, offering an eco-friendly alternative to traditional petroleum-based plastics. They are often biodegradable or compostable, which reduces environmental impact and fossil fuel dependence.
Unlike conventional plastics, bioplastics can break down naturally, contain fewer toxic chemicals, and have a lower carbon footprint due to the CO2 absorption by their source materials. There are four main types of bioplastics: bio-based plastics, biodegradable plastics, compostable plastics, and oxo-degradable plastics, each with specific properties and environmental benefits.
The production of bioplastics involves sourcing raw materials, polymerising plant sugars into lactic acid, compounding with additives for specific applications, and processing through extrusion or moulding. The finished products undergo cooling and additional treatments to stabilise the materials.
Bioplastics help reduce plastic pollution and biodiversity loss, using renewable resources to cut greenhouse gas emissions. They are designed to decompose naturally, minimising their environmental impact and supporting biodiversity preservation. Although still developing, bioplastic recycling offers further sustainability opportunities.
Common applications of bioplastics include packaging, construction materials, agricultural products, medical devices, and consumer goods. They are used in food packaging, beverage bottles, and single-use items, providing sustainable alternatives to traditional plastics.
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.
