Waste to X Technologies
Grate Combustion Systems
Reliable technology

Continuously improved and optimised

Grate combustion is the best-proven thermal waste treatment technology for mixed municipal solid waste and non-hazardous industrial waste, and the heart of any modern, state-of-the-art Waste to Energy (WtE) plant. We have constantly optimised, developed and expanded our grate combustion systems to meet changing statutory requirements. It is the most advanced technology regarding environmental sustainability, operational reliability and cost-effectiveness. For that, we offer the full circle – from project pre-study to consultancy, engineering, construction and services along the whole lifecycle.

Our grate systems efficiently process various waste types – without the need for extensive pre-treatment. They accommodate wide variations in:

  • Moisture content

  • Calorific value

  • Composition (organics, plastics, metals, inert materials)


This flexibility reduces operating costs and simplifies waste logistics.

Advanced combustion control ensures complete burnout and optimal heat generation. Combined with high-efficiency boilers, our systems deliver dependable production of electricity, steam, and district heating. The Kanadevia Inova incineration technologies combine reliability, environmental performance, and operational simplicity – helping communities turn waste into valuable energy while reducing landfill dependence and carbon impact.

Combustion detail

Well-proven and reliable combustion technology

With minimal pre-treatment requirements and straightforward design for operation and maintenance, our grate incineration offers:

  • Lower operating expenses

  • Reduced process complexity

  • Long equipment lifetime

It’s a solution that pays off over decades of operation. Whether for small communities or megacities, our grate systems can handle waste volumes from 50,000 to over 500,000 tonnes per year. The modular design ensures tailored solutions for any capacity.

With grate incineration technology from vonRoll, EVT, Lentjes, DBA, Noell, Steinmüller and Vølund, Kanadevia Inova has many years of industrial experience in this field, enabling us to best serve our customers' needs for new plants, as well as servicing and retrofitting existing plants. An advantage is our project pre-study, which evaluates feasibility before the project starts as a decision base for both sides, before the next steps.

Hazardous waste treatment

Treating hazardous waste is about the safe incineration (destruction) of the dangerous material contained in the hazardous waste. Moreover, issues such as the circular economy and energy recovery are also increasingly important.

Flue gas treatment

Incinerating waste produces exhaust gases laden with diverse pollutants. Different processes are used to remove these pollutants before the purified flue gas leaves the plant safely through the stack.

Carbon capture

Capturing carbon dioxide (CO2) from the flue gas produced in hard-to-abate industries and properly storing it (a process called carbon capture and storage or CCS) is a key component of most governments’ net-zero strategies.

Energy recovery

Recovering the energy content of waste is a key component of WtE technology. Since the process is largely renewable and involves only a low level of emissions, it also helps significantly reduce greenhouse gases.

Residue treatment

Thermal waste treatment produces residues which can be either reused or landfilled. The principal components are slags and ashes, consisting mostly of non-combustible waste constituents such as glass, minerals or scrap metals.

EcoFlex™ WtE plant solution

The new pre-engineered EcoFlex™ solution provides a modern waste infrastructure based on proven in-house technologies, allowing a cost-optimised design of single-line Waste to Energy plant construction and operation.
