RAWS Tech HK has revolutionized the way we think about plastic decomposition. Our advanced technology accelerates the natural breakdown of plastics, making them biodegradable in various environments. By utilizing a unique combination of enzymes and microbial processes, RAWS ensures that plastic waste is transformed into harmless organic compounds, reducing environmental impact and promoting sustainability.

RAWS biodegradation supercharges this process. It uses thermal ( Ambient Temperature) and UV energy with special “initiators” to create rapid free radicals—tiny reactive particles that smash the plastic’s molecular structure 100 times faster. These radicals break the plastic into bite-sized pieces for microbes to digest. Both actions—free radical breakdown and microbial digestion—happen at the same time.

Thermal degradation breaks down plastics into smaller molecules like ketones and aldehydes when heated. In landfills (oxygen-free environments), microbes digest these chemicals, turning them into CO₂ through steps like oxidation and decarboxylation. Methane can form if specific bacteria are active, but CO₂ is the main byproduct.

The radicals keep breaking the plastic until it’s no longer a polymer, while microbes eat the leftovers. The end result? Mostly water, CO₂, and less than 1% harmless biomass. Tests like ASTM D5511 and D5526 prove this works in anaerobic (no oxygen) conditions, where heat, UV light, and biodegradation all team up.

In short: RAWS speeds up plastic breakdown using heat and light, making microbes’ job easier. Landfill conditions help this process, with CO₂ as the main output. Methane is rare unless specific bacteria are present. The whole system is validated by science, showing plastics can break down safely and efficiently without lingering in the environment.

Science Behind the Biodegradation

First, microbes use enzymes to break the chemical bonds in ketones and aldehydes, releasing energy and creating acids. Next, these acids lose a carbon atom as CO₂ gas—a step called decarboxylation. While methane (a greenhouse gas) can sometimes form if specific bacteria are present, most of the timeH2o and CO₂ is the main result.

The whole process depends on factors like the type of plastic, temperature, and which microbes are around. Landfills are messy environments, so reactions vary. Importantly, methane isn’t made unless the right bacteria are active. If conditions aren’t ideal for these bacteria, the breakdown still happens but skips methane production.

In short, heat cracks plastic into smaller chemicals, landfill microbes “eat” them, and CO₂ is released. Methane is a possible byproduct but not the main focus here. The speed and details depend on the landfill’s setup and the microbes involved.
