New process makes ‘biodegradable’ plastics truly compostable
A film of PLA (polylactic acid) plastic immediately after being placed in compost (left) and after one week in the compost (right). Embedded with an enzyme, the PLA plastic can biodegrade to simple molecules, making it promising as a future alternative to a non-degradable plastic.

Title: A Review on Plasticizers and Eco-Friendly
Bioplasticizers are derived mainly from biomass sources including agricultural products, it’s by-products and waste. Regardless of the biomass source, ideal bioplasticizers are expected to be...
Chemistry can help make plastics sustainable — but it isn’t
Plastics are a staple ingredient in product design and manufacture, and their use, especially as single-use items such as water bottles and food wrappings, is expanding. The total weight of...
Bioplastics—are they truly better for the environment?
More than eighteen trillion pounds of plastic have been produced to date, and eighteen billion pounds of plastic flows into the ocean every year. It ensnares the marine animals we cherish and...
Here's A Truly Biodegradable Algae-based Bioplastic You Can
The plasticizer is water, and an additive is a natural dye. Talep boils the agar mixture to around 80° Celsius (176°F) to make a material that bears a close resemblance to thin plastic. Once melted, the molten liquid is transferred into a mold. The liquid takes on a gel-like consistency when the temperature drops to below 20° Celsius (68°F).
- Are plasticizers biodegradable?
- Plasticizers are additives used to ensure flexibility to polymer blends and thereby to increase their processability. As the typical plastic component phthalates and other fossil-based components contribute environmental issues since such compounds are not biodegradable.
- What is a plasticizer & how does it work?
- The plasticizer is a compound added to the plastic manufacturing process to enhance key properties such as flexibility, processability, and resistance to extreme temperatures. By forming non-covalent bonding or physical action in the plastic matrix, the plasticizer effectively improves the softness and molding plasticity of the material [3, 4].
- Can plasticizers be used in food packaging environments?
- This demonstrated excellent performance compared to the 10.94% migration rate of DOTP-50 in acidic food with pH < 5.0 after 240 h, indicating that these plasticizers can be safely used in the corresponding food packaging environments. Weight loss of PVC films in food simulant tests.
- What are biodegradable thermoplastics & plasticizers?
- To overcome these problems, researchers began to focus on biodegradable thermoplastics and plasticizers. Plasticizers is a highly branched polysaccharide stored in plants as an alternative to currently used non-biodegradable plasticizing compounds.
- Why are plasticizers used in the manufacturing process?
- To address this issue, plasticizers are used in the manufacturing process. The plasticizer is a compound added to the plastic manufacturing process to enhance key properties such as flexibility, processability, and resistance to extreme temperatures.
- Where do natural plasticizers come from?
- Several natural plasticizers originate from agricultural products like trees, oleaginous plants, cereals, vegetables, and fruits, as well as their waste . Utilizing bio-based wastes as natural plasticizers, various polymers and materials have been tested.
