ตอบ Biodegradable plastics are similar in quality to normal, petroleum-based plastics. The difference is that when buried in a site with the right temperature, high level of humidity, and sufficient bacteria, bioplastics decompose into carbon dioxide, water, and biomass — the natural growth factors for plants.
Some bioplastics are made of biobased materials like corn, cassava, or bagasse. Through a safe and proven industrial process, these sustainable materials become eco-friendly packaging that solves plastic waste problems.
We use natural sources such as bagasse and fibers from corn and cassava. Our products meet the global standards for compostable plastics, with ISO 17088, ASTM D6400 (USA), EN 13432 (EU), and TISI 17088-2555 (Thailand) certifications.
BLeaf bioplastic bags contain no PP, PE, or any other non-compostable plastics. Our products are free of OXO, which is a chemical substance that creates microplastics. Our bio bags are white and stretchy, and can support up to 4 kilograms of weight.
PLA bags, trays, straws, eating utensils, and cups – at 58 °C temperature and with the right proportion of humidity and bacteria, these products take approximately 6 months to 2 years to decompose. The process takes longer in varying conditions.
Coir-based plant pots – take around 8 months to decompose when used to grow plants in or buried into the soil.
Bagasse-based food containers – decompose within roughly 45 days after burial. Burying these with food waste expedites the process, as the bacteria from food and the humidity from soil are great catalysts for the decomposition.
Paper straws – take 4–5 months to completely decompose.
With high temperature and humidity, bioplastics start to break up into pieces. Microorganisms then take from 6 months to 2 years to digest the elements, depending on their shape and decomposition conditions. When the process is complete, biodegradable products become carbon dioxide, water, and biomass that plants need as natural growth factors, leaving zero microplastics to harm the environment.
Microplastics refer to plastics that are shorter than 5 mm in length. These include anything from microbeads, synthetic fiber from clothing, pieces from vehicle tires, fishing nets, and other non-compostable plastics. Through time and degradation, these plastics break down into tiny pieces that are hard to contain and dispose of. This means microplastic contamination happens very easily and this has long-term consequences to the environment. It’s important to note that large-sized plastic items are no safer, as they also break down into smaller pieces over time.
The safe temperature for bio food trays and bags is at 55 °C, and 85 °C for bio eating utensils. If overheated, the products won’t melt, but they’ll begin to lose shape. For maximum safety, please refer to the instructions.
The ideal temperature for PLA decomposition is 55–60 °C, as high temperature and humidity speeds up the working of enzymes needed in the process.
Our eco-friendly products require no extra maintenance. They can last over one year when kept safe from rodents and insects, under room temperature and low humidity.
Yes! Our biodegradable products are FDA-certified and absolutely safe for food.
