Waste Plastic
to Fuel.
Olive Green International converts Sri Lanka's non-degradable plastic and tire waste into pyrolysis oil, carbon black, and paraffin — a zero-waste, closed-cycle Waste-to-Energy solution engineered for councils, investors, and industry.
A crisis buried in plain sight.
Sri Lanka generates thousands of tons of municipal solid waste daily. Plastic and rubber — non-degradable and difficult to safely recycle — accumulate in open dumps and unlined landfills with no long-term plan.
In April 2017, the collapse of the Meethotamulla landfill claimed 32 lives and displaced hundreds of families. It remains a stark reminder of what happens when waste is treated as an afterthought rather than a national infrastructure priority.
We built Olive Green International to turn that liability into fuel.
A cluster-model PPP for waste-to-energy.
Local councils supply the land, permits, and waste stream. Olive Green International handles design, procurement, construction, commissioning, and operator training. One reactor per cluster. Zero landfill.
- Land for the plant footprint
- Environmental & operating permits
- Guaranteed daily waste feedstock
- Access to community collection network
- Reactor design & procurement
- Turnkey construction & commissioning
- Operator hiring & technical training
- Offtake logistics for oil, carbon black & paraffin
A closed-cycle process, engineered end-to-end.
No incineration. No hazardous emissions. Every output stream — oil, carbon black, paraffin — is captured and sold.
Plastic & Tire Waste
Feedstock arrives from council collection routes.
Washing
Contaminants and organics removed.
Shredder
Material reduced to a uniform particle size.
Storage & Drying
Moisture stabilised before thermal processing.
Briquetting
Compressed into dense, high-yield feed pellets.
Pyrolysis Reactor
Oxygen-free thermal decomposition. No combustion.
Condenser Module
Vapours cooled and separated into fractions.
Pyrolysis Oil
Clean synthetic oil, stored and distributed.
Impact measured two ways.
Closed-cycle process — zero direct hazardous emissions
Flue gases pass through high-temperature scrubbers
Substantially lower CO₂ output than incineration
99% material recycling rate across feedstock
Treats plastic and rubber that cannot otherwise be recycled
Pyrolysis oil functions as a clean industrial energy source
Investor-ready. Council-approved.
Every layer of feasibility has been independently validated before capital deployment.
Validated by international engineering.
Plant design co-developed with International Trade House and reviewed by an experienced Sri Lankan engineering panel.

Engineering local waste solutions for Sri Lanka.
Olive Green International (Pvt) Ltd was established in Battaramulla to address Sri Lanka's escalating municipal plastic accumulation and heavy reliance on imported furnace fuels. Registered under the Companies Act of Sri Lanka, our team combines local research expertise with thermal process engineering to convert non-recyclable polymer waste into high-calorific industrial energy products.
"Our objective is straightforward: stop burying valuable polymer energy in Sri Lankan landfills. By recovering high-grade fuel oil locally, we lower industrial fuel import bills while cleaning our cities."

Pyrolysis Oil & Waste Recovery FAQs
Everything you need to know about our clean-tech waste plastic conversion and industrial fuel specifications.
What is pyrolysis oil and how is it produced from plastic waste?
Pyrolysis oil is a high-grade synthetic fuel oil produced by thermal degradation of waste plastics and tires in an oxygen-free reactor at high temperatures (400-500°C), converting solid polymer waste into heavy fuel oil, carbon black, and combustible gas.
How does pyrolysis oil compare to heavy fuel oil (HFO) or furnace oil?
Pyrolysis oil has a gross calorific value (GCV) of ~10,200 kcal/kg, comparable to conventional industrial heavy fuel oil (HFO), but burns cleaner with lower sulfur content, offering a cost-effective and low-carbon alternative for industrial boilers, furnaces, and kilns.
What is the daily processing capacity of the Olive Green plant?
The plant is engineered with a modular batch-to-continuous pyrolysis system capable of processing up to 20 metric tons of municipal and industrial waste plastic per day, operating at 99% recycling efficiency with virtually zero landfill output.
What secondary products are generated besides pyrolysis fuel oil?
In addition to pyrolysis fuel oil, the process yields high-purity industrial carbon black (used in rubber manufacturing and pigments), refined paraffin wax, and non-condensable syngas recycled back to power the plant.
