The Good

Compostable (or biodegradable) in both home and industrial compost conditions
Does not break down into micro-plastic particles
The use of compostable materials in flexible packaging aids in the development a functioning circular economic system. This is particularly important in flexible packaging as it is an area that is very challenging for mechanical recycling
The increased use of compostable materials creates market demand that will lead to the development of important composting infrastructure
Reduces reliance on fossil fuels and increases the use of renewable plant-based materials
Promoting the development of a composting waste stream also helps to address the problem of the excess waste to the landfill (in the form of food scraps) which has a significant contribution to greenhouse gas emissions

The Bad

More expensive than virgin and recycled plastic materials
A majority of compostable materials are hygroscopic, meaning they and have a tendency to take on moisture. This limits the shelf-life for products with high moisture or oil content
Despite the exciting opportunity compostable films and laminates represent to develop a productive circular economy, currently rates of composting are low
If compostable bioplastics end up in a landfill, over time they will generate methane, a greenhouse gas far worse for the environment than carbon dioxide
There is a lot of misinformation in relation to compostable materials and they lack universally-accepted labelling and certification standards

Raw materials

Bio PBS

Bio Polybutylene succinate (BioPBS) offers a sustainable alternative to traditional petroleum-based packaging materials, derived from renewable resources like cornstarch. It can be molded into various forms such as films, sheets, and containers, and boasts biodegradability, reducing landfill waste. With superior mechanical properties sourced from starchy vegetables like sugarcane and cassava, BioPBS is an appealing choice for industries requiring strength and durability.

Cassava

Cassava, a global staple food crop, yields sought-after starch from residual plant material post-juice extraction, which is processed for various bio-based packaging applications like bags, films, and containers, enabling businesses to fulfill consumer demand for climate-positive products while maintaining desired performance benefits.

Cellulose

Cellulose, derived from renewable sources like wood, pulp, bamboo, or hemp, offers a plant-based alternative to traditional petroleum-based packaging, boasting compostability and recyclability.

Sugarcane

Sugarcane is pivotal in bioplastic production, as it undergoes biorefining where its juice is extracted, fermented into ethanol, and further processed into various chemicals like butanol, a key component in bioplastic manufacturing.
