Anaerobic Digestion is Now Economically Viable in Europe

Anaerobic Digestion is both a waste treatment technology and a highly sustainable energy technology. Recent rises in energy costs, coupled with EU member state incentives, and waste management policy, now mean that economic viability has been attained.

This old blog post from December 2006, is an archive page. We have kept this page “live”, as we think it is a historically relevant page, which makes a bold profit claim which seems to have been proved correct, on the basis of the recent growth in Biogas Plants.

Our article explains how this technology can also provide a politically secure energy supply, and argues that there should be more fiscal assistance to promote Anaerobic Digestion.

What the world thinks of the anaerobic digestion and biogas process in 2018:

What to consider when building your anaerobic digestion plant

Good plant design and separation of equipment may help prevent losses and lead to competitive and sustainable insurance premiums.

Recent claims in the anaerobic digestion (AD) industry have led to a focus on whether developers are taking the correct planning considerations into account when building their AD plants.

By reviewing the risks prior to construction and incorporating mitigations within the design and build of the plant, developers will be able to demonstrate an improved risk which will be viewed favourably by insurers.

Considering risk mitigation during the design phase can avoid the eventuality of losses. For example, if you have wide separation between key plant items, you may save your plant from total loss by allowing the fire brigade get to the site in time and to contain the fire to a smaller section of the plant. It is easier and cheaper to replace an engine, for example, than the entire plant.

The majority of build and maintenance contractors recognise that it is good practise to build biogas plants using experienced contractors; to install well-recognised plant and machinery with a proven track record, and to manage risks with, for example, good operational housekeeping. While all good engineers will undertake to design and build a suitable plant, often little consideration is given to plant design should a fire occur.

In the UK, fire risk assessments are primarily concerned with personnel safety, and workers’ ability to escape a fire, whereas a property insurer’s objective will be to try to reduce exposure to building and machinery losses from fire. via Renewable EnergyJLTSpecialty

Certification scheme will “revolutionise” UK anaerobic digestion industry

A newly launched certification scheme could be a breath of fresh air for the UK’s anaerobic digestion (AD) and biogas industries, according to Duncan McPherson, finance director at CooperOstlund.

As 2017 drew to a close, the UK’s Anaerobic Digestion and Bioresources Association (ADBA) launched a new AD certification scheme, the first of its kind in the UK, designed to support operators of AD plants in improving their operational, environmental, and health and safety performance, in particular in terms of energy generation and digestate quality.

“Since the introduction of government-driven subsidies for generating renewable energy, including the Renewable Heat Incentive (RHI), Feed-in Tariffs (FiTs) and the Renewables Obligation (RO), anaerobic digestion (AD) has quickly shifted from innovative thinking to established technology. In fact, the number of UK AD facilities has grown by nearly 500% in five years – from 100 in 2013, to 578 in 2017.*” McPherson writes.

“Although continued degressions have seen this figure seemingly decelerate, more than 100 million tonnes of organic material is now treated by AD every year. Alongside diverting resource away from landfill and offsetting carbon emissions, this generates enough energy to power one million homes nationwide.”

Anaerobic Digesters as a Tool for California’s Clean Transportation Efforts

As one of the most populous states in the nation and a center of agricultural activity, California faces a waste disposal problem.

Organic waste sent to municipal waste water treatment plants and landfills from cities, businesses, industry and agricultural operations not only take up significant space but are also a significant, if lesser-known, source of greenhouse gas (GHG) emissions.

In fact, California’s largest single source of fugitive methane, a powerful greenhouse gas with a global warming potential 28 to 36 times higher than carbon dioxide, is the state’s dairies.

In another example, uncontrolled decomposition of food and green waste in landfills leads to heavy production of methane gas, of which 34-51% escapes the typical landfill capture system.

With proper collection, however, and refinement through anaerobic digestion, the energy-rich gases seeping from our waste management systems can be processed into renewable replacements for diesel and other fuels.  via ADTool for California
