Malaysia faces a significant challenge in municipal solid waste management, generating approximately 8.3 million tonnes of food waste annually, which translates to roughly 17,000 tonnes daily. When disposed of in non-engineered landfills, this organic waste undergoes anaerobic decomposition, releasing methane gas. Methane is a potent greenhouse gas that is 25 to 80 times more effective at trapping heat than carbon dioxide over a 20-year timeline. Globally, food waste accounts for 8% to 10% of total greenhouse gas emissions.

A major, overlooked contributor to this problem is the "Dead-Weight" logistics penalty and subsequent disposal of recalcitrant tropical fruit biomass, specifically durian husks. Durians are typically transported whole. However, 65% to 80% of the fruit's total weight consists of the non-edible husk. For every 10 tons of cargo shipped from farms to urban markets or processing hubs, up to 7 tons are effectively waste that is discarded at the consumer destination.

Because durian peels are exceptionally tough, fibrous, and difficult to decompose due to a biological shield of lignin, they do not fit into standard food waste processing machinery and frequently clog industrial grinders. Consequently, local composting facilities in Malaysia often reject them, forcing them into landfills where they slowly rot, or leading farmers in rural regions to resort to open burning. Open burning releases carbon dioxide, carbon monoxide, and hazardous fine particulate matter into the atmosphere.

Furthermore, durian peels have high moisture and sugar content. In tropical environments where ambient heat consistently exceeds, they undergo rapid microbial decay and "fiber ruin" within 24 to 48 hours. This decay degrades the valuable cellulose and lignin fibers, rendering the biomass useless for high-value upcycling like bioplastics or textiles if not stabilized immediately at the source
