From biogas to green gas: we are helping the market get moving
Biogreengas
Biogas and green gas are valuable, much-sought-after products that can help industry, water authorities, and waste processors increase the sustainability of their processes in a cost-neutral and positive way. But they present organisations with a considerable task in terms of technology, safety and operations. Witteveen+Bos offers integrated support for this task – from the design of processes and installations to overseeing permit processes – so that biogas and green gas projects can be executed in a safe, sustainable and scalable manner.
Witteveen+Bos has experience with sludge digestion in wet residual flows from sewage treatment plants and waste processors. From this process, biogas can be produced, which can then be upgraded to green gas. Because of its similar properties to natural gas, green gas can be fed into the natural gas network. Both biogas and green gas have a lower carbon footprint than natural gas and can contribute to more sustainable heating.
Why choose Witteveen+Bos?
- knowledge of and more than 50 years’ experience with sludge digestion, gas treatment to produce green gas, sustainable heat generation, and electricity supply;
- complete modelling (digital twin) of the energy system at a sewage treatment plant for a cost-efficient, circular and sustainable design that is resistant to grid congestion;
- integrated approach: from technology to sustainability studies and permits;
- designs based on ‘value’: investment costs are not the only consideration – operating costs and sustainability are also incorporated into our design processes.
Collaborating on large-scale, future-proof sludge digestion
The centralised, large-scale digestion of sewage sludge at central sludge processing installations has proven to be a cost-efficient and sustainable option. But constructing such an installation involves a range of challenges. What is the optimal design and how can you ensure that it satisfies the requirements of the water authority? Witteveen+Bos has extensive experience in designing these installations together with water authorities and contractors in construction teams, including recently in Ede and Geestmerambacht. This form of collaboration ensures that designs satisfy the wishes of both client and contractor.
Clean, reliable heat and electricity
Traditionally, sewage treatment plants use biogas in cogeneration installations to produce heat and electricity. But this causes local NOx and CO2 emissions, which can lead to objections in permit processes and jeopardise reaching CO2-reduction targets. That is why we not only look at the primary process, but also at emission-free heating for the digestion process and electricity availability and security. With our broad expertise in both heating and electricity, we can provide optimal support and help our clients achieve their sustainability ambitions and provide a reliable service.
