The Problem We Solve

Why Uncontrolled Burning is No Longer Acceptable

With growing urban density and increasing volumes of non-biodegradable waste, conventional disposal methods are causing serious environmental and public health damage across India. Open dumping, landfilling and uncontrolled burning of mixed waste — especially thin plastics — are among the leading contributors to soil contamination, water pollution and air quality degradation.

Unscientific burning vents high-temperature, pollutant-laden flue gases directly into the atmosphere with no treatment — harming communities, violating environmental norms, and creating long-term liability for the organisations responsible. KOALA incinerators are the engineered alternative: controlled, clean, and compliant.

🗑️
Open Dumping & Landfilling

Leads to leachate contamination of groundwater and soil, rodent infestation, and long-term land degradation — especially with mixed plastic and organic waste.

🔥
Uncontrolled Open Burning

Releases toxic gases, dioxins and particulate matter directly into the air with no treatment. Illegal under current environmental regulations and harmful to nearby communities.

🏥
Untreated Biomedical Waste

Infectious healthcare waste improperly disposed of poses serious risks of disease transmission, regulatory non-compliance, and safety hazards for waste handlers and the public.

🌊
Ocean & Water Body Dumping

Plastic and mixed waste entering water systems destroys aquatic ecosystems, contaminates drinking water sources, and is a growing environmental crisis across coastal Kerala.

Koala Incinerators

Thermal Engineers started our career as Govt approved boiler repairers and erectors in the year 1980.

The Process

How a KOALA Incinerator Works

A controlled, multi-stage process that destroys waste completely and cleans the emissions before they reach the atmosphere.

📥
Waste Loading

Dry solid or segregated waste is loaded into the primary combustion chamber through the loading door. Batch or continuous feeding depending on the model.

🔥
Primary Combustion

Controlled air combustion in the refractory-lined primary chamber destroys waste at high temperature. No separate ignition fuel needed in normal operation.

♨️
Secondary Burn

Exhaust gases pass through a secondary chamber (biomedical models) at 1050–1200°C with a minimum 2-second residence time, ensuring complete burnout of all volatiles and smoke.

💨
Emission Purification

Flue gases pass through a water scrubber and activated charcoal filter to remove particulate matter, odours and harmful pollutants before clean discharge to atmosphere.

Environmental Responsibility

Clean Technology. Real Impact.

KOALA incinerators are designed to solve the environmental problems caused by uncontrolled waste disposal — not create new ones.

Every KOALA incinerator is engineered around a fundamental principle: the emission leaving the system must be cleaner and safer than the alternatives it replaces. Uncontrolled burning, landfilling and dumping create chronic environmental damage. KOALA's multi-stage emission purification — scrubbers, charcoal filtration, cyclone separators and secondary combustion chambers — addresses the pollutant streams at every stage.

For biomedical waste, the system is designed to meet the Biomedical Waste Management Rules, 2016 and CPCB emission standards, providing healthcare facilities with a compliant, defensible, and genuinely safe disposal pathway. Optional wastewater management handles the scrubber effluent for complete environmental closure.

We believe responsible waste management is not a luxury — it is an obligation for every institution, residential community and business. KOALA makes that obligation affordable and achievable.

Common Questions

Frequently Asked

Everything you need to know before choosing a KOALA incinerator.

The right size depends on your daily waste volume (in kg), the type of waste, and how many hours per day you plan to operate the unit. Our engineering team can help you size the correct model — simply contact us with your approximate daily waste quantity and waste type, and we will recommend the right model from our KI-5 (5 kg/hr) to KI-Custom (up to 300 kg/hr) range.
When operated and maintained as recommended, KOALA incinerators are virtually smoke and odour free. The water scrubber and activated charcoal filter remove particulate matter and foul odours before discharge. Configured models also include flue gas recirculation for further cleaner operation. Improper waste loading (excessively wet waste, oversized loads) can cause temporary visible emissions — which is why we provide operator training with every installation.
General models handle dry solid waste including plastics, paper, packaging, food-contaminated waste, and general household or institutional waste. Biomedical models (KI-BM) are designed for pathological waste, selected pharmaceuticals, hazardous healthcare waste, and laboratory materials — when properly segregated. Wet waste and certain waste streams may require separate handling or are not suitable for incineration — our team will advise based on your specific waste profile.
Yes. KOALA incinerators reduce waste to sterile ash — achieving over 90% volume reduction. The high combustion temperatures destroy pathogens, organic matter, and volatile compounds. The resulting ash is inert and substantially easier and safer to transport and finally dispose of than the original waste.
Requirements vary depending on the model capacity, waste type, and location. Biomedical waste incinerators must comply with the Biomedical Waste Management Rules, 2016 and CPCB norms. Industrial and larger models may require environmental clearances. Our team assists with the technical documentation required and will advise you on the applicable regulatory requirements for your specific installation.
Operating costs are low. In normal operation, no separate ignition fuel is required — the waste itself sustains combustion. The main running costs are electricity for controls and blowers, water for the scrubber (recycled in some configurations), and periodic maintenance. KOALA systems are specifically designed for economical operation without sacrificing emission control performance.
Yes. While we are based in Kerala and serve the local market extensively, KOALA incinerators are supplied and installed across India. Marine and offshore models are supplied for vessels operating in Indian waters and internationally. Contact us with your location and requirements for delivery and installation details.
