Waste treatment & refining technology

We license the process.
Our partners run the plant.

Enviro Chem Industries develops technology for waste engine oil recovery, waste hydrocarbon refining and waste plastic depolymerization — then licenses it to joint ventures we hold a lasting stake in.

What we do

Waste in. Fuel, power and materials out.

ECI designs, fabricates and operates turn-key chemical engineering systems for waste treatment and energy recovery. We run the plant ourselves, so we specify it as an operator rather than a vendor.

01 / RECOVER

Waste treatment & material recovery

Landfill mining and zero-waste systems that sort historic and fresh refuse, pulling metals and inerts out and routing each remaining stream to the process that suits it.

02 / CONVERT

Pyrolysis & thermal conversion

Pyrolysis reactors crack polymeric waste into light hydrocarbon liquid — low sulphur, low wax. Designed, fabricated and operated in-house.

03 / REFINE

Distillation & product finishing

Atmospheric fractionation cuts recovered and waste-derived oil into white spirit, gas oil and heavy fuel oil, then polishes each cut to a saleable specification.

04 / GENERATE

Gasification & power

Gasification of refuse-derived fuel produces syngas at volume. Both gas and liquid fuel streams can drive generator banks for industrial estates or grid supply.

Technology

Three processes. One transformation logic.

Each technology takes a waste stream that has run out of use in its original form and returns it to the value chain as a refined feedstock or product.

Waste engine oil recovery

Collection and pre-treatment of used engine oil, recovering base-oil fractions for re-refining rather than disposal or low-grade burning.

Input: used lubricants

Waste hydrocarbon refining

Refining of recovered and waste hydrocarbon streams into fuel-grade and industrial-grade output, engineered for site-specific feedstock variability.

Input: mixed hydrocarbons

Waste plastic depolymerization

A modular depolymerization unit that breaks waste plastic into hydrocarbon feedstock, built for both owned operation and third-party licensing.

Input: mixed plastic waste

Products

What comes out is oil, gas and power.

Everything below starts as waste — material heading for a landfill, an incinerator or a disposal contractor. Each output is a specification-driven product with an existing industrial buyer, not a by-product looking for a market.

Liquid fuels

Transport diesel

The middle cut off the fractionation column, clay-polished for colour and stability.

200–350°C cut

Fleet · Haulage · Generator sets

Solvents

White spirit

The light overhead cut, recovered as an industrial solvent rather than blended away.

Below 200°C cut

Coatings · Cleaning · Manufacturing

Heavy fuels

Mazut / HFO

Column bottoms held in heated storage as bunker fuel and industrial heating oil.

Above 350°C cut

Marine · Boilers · Process heat

Gas

Syngas

Produced at volume by gasifying the non-plastic refuse that arrives alongside our polymer feed.

CO + H₂

Gas engines · Process fuel

Solid fuel

Carbon char

The solid residue of cracking, cooled, screened and briquetted as a coal replacement.

Licensing model

We contribute the technology. We hold the equity.

ECI licenses its process technology and provides operations & maintenance support to each joint venture, and takes an equity stake in return — without contributing cash capital.

01In-kind IP contributionPatents and process know-how contributed at formation, valued for shares in the JV.

02Convertible fee structureAccrued license and O&M fees convert to equity at the commercial operation date.

03Performance earn-inAdditional shares earned once a plant sustains guaranteed yield and uptime.

Equity stake

Portfolio

Current joint venture.

ECI develops waste-to-fuel plants it invests in and operates alongside joint-venture partners — structured around feedstock security and real plant economics, not technology licensing alone. More projects are in development across Thailand, Singapore and Laos.
