High population density, increased economic activity and evolving consumer patterns have led to rapid urbanisation, making waste management a major challenge. Sri Lanka is facing a critical waste management crisis as municipal dumpsites often lack proper controls and contribute to pollution.
Traditionally, composting has been the primary waste management method since nearly 65 percent of waste is perishable and biodegradable. However, the composting process generates significant residue of long-term degradable materials like wood and coconut shells, which perpetuates pollution.
In response, Sri Lanka has launched the world’s first autothermal pyrolysis plant, a groundbreaking step in sustainable waste management. Developed collaboratively by local universities and research centres, this innovative facility converts compost residues into biochar to minimise pollution and enhance soil quality.
Installed at the Karadiyana Mihisaru Resource Management Center in late 2023, the plant is designed to carbonise two tons of compost residue at a time. Continuous research and training initiatives ensure optimal operation with interns from the University of Colombo involved in pyrolysis optimisation.
The official handover ceremony of the plant in June was attended by a number of dignitaries and marked a milestone in Sri Lanka’s commitment to sustainability.
This pioneering project exemplifies how research and collaboration can transform environmental challenges into sustainable solutions, positioning Sri Lanka as a leader in waste management innovation.
