KOALA incinerators by Thermal Engineers provide safe, cost-effective and environmentally responsible waste destruction — from compact 5 kg/hr residential units to 300 kg/hr industrial and biomedical systems.
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.
Leads to leachate contamination of groundwater and soil, rodent infestation, and long-term land degradation — especially with mixed plastic and organic waste.
Releases toxic gases, dioxins and particulate matter directly into the air with no treatment. Illegal under current environmental regulations and harmful to nearby communities.
Infectious healthcare waste improperly disposed of poses serious risks of disease transmission, regulatory non-compliance, and safety hazards for waste handlers and the public.
Plastic and mixed waste entering water systems destroys aquatic ecosystems, contaminates drinking water sources, and is a growing environmental crisis across coastal Kerala.

Thermal Engineers started our career as Govt approved boiler repairers and erectors in the year 1980.
A controlled, multi-stage process that destroys waste completely and cleans the emissions before they reach the atmosphere.
Dry solid or segregated waste is loaded into the primary combustion chamber through the loading door. Batch or continuous feeding depending on the model.
→Controlled air combustion in the refractory-lined primary chamber destroys waste at high temperature. No separate ignition fuel needed in normal operation.
→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.
→Flue gases pass through a water scrubber and activated charcoal filter to remove particulate matter, odours and harmful pollutants before clean discharge to atmosphere.
Across every model and segment, KOALA incinerators share the same engineering commitments.
Controlled air supply and optimised chamber design ensure complete waste destruction with economical operating costs.
Water scrubber, activated charcoal, and cyclone separators included in configured models. Virtually smoke and odour free operation.
High-grade refractory lining resists thermal stress, reduces heat loss and maintains efficiency across thousands of operating hours.
Delivered nearly complete for fast on-site installation with minimal civil work. Reduces commissioning time and site disruption.
Waste is reduced to clean, sterile ash — over 90% volume reduction simplifies final disposal and eliminates health risk from residue.
Designed for ease of use with simple tuning and user-friendly operation. Operator training provided with every installation.
Heavy-duty construction with high-grade stainless steel in medical models. Built for long service life with minimal maintenance.
Comprehensive Annual Maintenance Contracts, spare parts, operator training, and engineering assistance from Thermal Engineers.
KOALA incinerators serve a wide range of residential, institutional, industrial, healthcare, and marine applications across India.
Modern apartment communities generate significant daily waste — much of it non-biodegradable plastics and packaging that cannot go to landfill. A KOALA incinerator installed on-site eliminates the dependence on municipal waste collection, reduces the volume of waste to sterile ash, and keeps common areas clean and odour-free. Ideal for gated communities, multi-storey apartments, and housing societies across Kerala.
The KI-5 and KI-25 are particularly well-suited, as they don't require specialised operators and can be managed by regular maintenance staff with basic training.
Healthcare facilities have a legal obligation under the Biomedical Waste Management Rules, 2016 to safely treat and dispose of infectious waste. The KI-BM series is purpose-built for this requirement — achieving over 90% volume reduction, complete sterilisation of pathological and hazardous waste, and full compliance with CPCB emission norms. Suitable for hospitals, clinics, diagnostic laboratories, veterinary facilities and blood banks.
Hotels and resorts generate daily mixed solid waste — food packaging, plastics, paper and general waste — that must be managed hygienically and responsibly. A KOALA incinerator provides a clean, on-site solution that eliminates odours, reduces waste volume to sterile ash, and keeps premises compliant with local waste management regulations. Especially relevant for resort properties in coastal Kerala where municipal collection may be unreliable.
Schools, colleges, university campuses and student hostels produce substantial daily waste from canteens, classrooms, and residential areas. KOALA incinerators provide a self-contained, low-maintenance solution that does not rely on municipal waste collection schedules. Simple enough for non-specialised staff to operate with basic training.
Industrial sites generate process waste, packaging, contaminated materials, and production rejects that require proper treatment. KOALA industrial incinerators handle high volumes continuously with low operating cost and full emission control. Suitable for textile mills, food processing plants, rubber and chemical industries, and any manufacturing unit with regulated waste streams.
Ships, offshore platforms, and remote marine facilities face strict MARPOL regulations on waste disposal at sea. KOALA custom incinerators can be designed for marine-rated installation, providing a self-contained, compact waste treatment system that operates reliably at sea with minimal maintenance. Suitable for cargo ships, passenger vessels, fishing fleets and offshore oil and gas platforms.
Pharmaceutical facilities and research laboratories generate hazardous, expired, or rejected product waste, contaminated packaging, and biological materials that require high-temperature destruction. The KI-BM series handles these waste streams safely with full APCE emission control, and optional heat recovery to improve energy efficiency of the overall facility.
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.
KOALA incinerators are a natural extension of 45 years of thermal engineering expertise from Thermal Engineers, Kerala.
KOALA incinerators are designed by the same team that has built IBR-certified industrial boilers since 1980. Deep combustion engineering expertise translates into better-designed, more reliable incinerators than general fabricators can offer.
Local manufacturing means faster delivery, on-site installation by our own engineers, and accessible after-sales service. You are not dealing with an agent — you deal directly with the people who designed and built your system.
KOALA systems incorporate many benefits of premium international incinerators while remaining budget-conscious. High combustion efficiency keeps operating costs low over the system's long service life.
From a 5 kg/hr residential unit to a 300 kg/hr custom industrial or marine system — KOALA covers the full spectrum. We also design and supply boilers, thermic fluid heaters and heat exchangers, making us a complete thermal systems partner.
