Landfill gas

Convert waste to energy efficiently with KTS ENGINEERING solutions

Waste generation is inevitable in an ever-growing population. But instead of just letting waste rot, you can now put it to work, which will both help the environment and provide your business with energy. Landfill gas is produced by the anaerobic decomposition of organic matter in municipal solid waste (MSW) and industrial waste. Produce heat and electricity using Jenbacher gas engines, which run on landfill gas.

How it works

To prevent the release of greenhouse gases into the atmosphere, while avoiding unpleasant odours and fires, the landfill gas must be continuously extracted in a controlled manner. Perforated pipes are embedded in the body of the landfill and connected to each other by a piping system with access to common mushrooms. Using a vacuum compressor, the gas is sucked out of the landfill body.

The composition of the landfill gas and its reproduction rate are primarily influenced by the waste. MSW contains between 100 and 300 kg of organic carbon per tonne. Microorganisms, without much difficulty, convert organic carbon into landfill gas through anaerobic digestion processes. Gassing is affected by factors such as waste composition, height and density of landfill storage, air temperature and precipitation levels. Landfill gas production starts a few years after the waste has been in the landfill and lasts from 8 to 30 years. With a calorific value of 3.5 to 5.5 kWh per Nm3 (35-55% methane), landfill gas is an excellent fuel for gas engines, which can be used efficiently to generate electricity.

Benefits and special features

  • Reliable and stable operation. The wide range of Jenbacher INNIO gas engines is specifically designed to operate at full load with high efficiency despite the low calorific value of the gas, fluctuating gas composition and pressure.

  • Special engine versions. High-quality and specially developed engine parts resist the corrosive impurities normally found in this type of fuel.

  • Efficiency. Electrical efficiency of up to 42%.

  • Environment. Alternative utilisation of landfill gas while using it as an energy source. Comprehensive exhaust gas control solutions, which are compliant with environmental standards.

  • Source of revenue. Revenues from electricity and heat production when fed into the public grid. Credits or special renewable energy feed-in tariffs “Green” tariff.

  • Mobility and rapid commissioning. The compact, containerised units are easy to move around and adapt to any change in design.

There are 18 INNIO Jenbacher landfill gas engines installed in Ukraine. Globally, INNIO Jenbacher gas engines are used in more than 1,700+ landfill projects worldwide. KTS Engineering, together with INNIO Jenbacher, offers its customers the benefit of accumulated experience, advice, and ready-made, proven solutions.
