Energy-from-Waste
We can advise on how to use waste as a resource for clean energy technologies in energy-from-waste initiatives.
Anaerobic Digestion (AD)
AD can help meet both renewable electricity and heat targets. Our experts have practical experience of working systems and are well placed to advise on whether AD is feasible for your project.
We assess critical parameters such as:
- The potential or current energy demands of a development and how this relates to the scale of an AD plant
- The availability of feedstock to determine if the scale of an AD plant fits with available resources
- The potential outlets in a local area for solid and liquid digestate
- The availability of the correct type of energy utilisation equipment and its impact on return on investment
If AD is the right technology, we can assist you with other aspects of implementation, such as the planning applications, resolving neighbourhood issues such as odour emissions, monitoring the purity of digestate and applying for environmental permits.
Energy-from-Waste
But there are many other energy-from-waste methods. We have waste specialists all around the world, so we are well aware of best practice. We can advise you on the equipment most applicable for your projects, that will produce suitable returns on investment, and which minimise risk
Energy-from-waste techniques that we constantly review include:
- Gasification technologies for converting waste wood, refuse-derived fuel and municipal waste into heat, power and cooling
- Anaerobic digestion technologies for converting putrescible materials into biogas that can then be used in Combined Heat & Power systems or as an alternative fuel for vehicles
- Fuel cell technologies for converting either biogas or synthesis gas into electrical power at high efficiency, with minimal emissions and noise.

What is Anaerobic Digestion
Anaerobic Digestion (AD) utilises naturally occuring bacteria to break down putrescible materials, in the absence of air, to produce a gas mixture called 'biogas'. The biogas produced by AD contains both methane and carbon dioxide, as well as traces of other gases such as ammonia and hydrogen sulphide. The methane component of biogas, which constitutes 50-55% of the volume, is the main constituent of natural gas, and therefore, this makes biogas a potential replacement for fossil fuels.
