Anaerobic Digestion News: Anaerobic Digestion Companies Grow From Hundreds t...: Anaerobic digestion companies are a major growth sector within the global marketplace.

Key Types of Anaerobic Digestion Companies

There are now a number of various sorts of anaerobic digestion companies. There are anaerobic food  waste digestion expert companies which will engineer, create, and then construct a complete and fully working AD Plant (DBC Contractors). A few of those specialists will go further compared to that even operating their AD Plants in addition as DBOOT Contractors (Design, Build, Own, Operate, Transfer).

There are also specialist service providers, calling themselves AD Companies, which design and construct just part of a biogas plant, such as the warmth exchangers, and/or CHP tools.

Within the industry of Design as well as Build Contractors in the industrialized nations these businesses are normally, as a general rule, expert firms in one, or more of the following anaerobic digestion plant customer areas: Read the full article here.

CHP Matters to Think About When Designing a CHP Scheme

Anaerobic Digestion News: CHP and 3 Important Considerations When Designing ...: An Introduction to CHP Add caption Combined heat and power ( CHP ) systems, are also known as cogeneration systems, and they greatly...

Ask yourself whether your business premises, industrial or organisational facility have a large heat and power load demand? Is there a Biogas Plant near you? If so, it’s worth exploring working with the Biogas Plant owner any possibilities for a Combined Heat & Power system. What is more you could be eligible for a grant , soft loan or green power price incentive to offset the cost of investing in this etchnology to make use of this energy-efficient and renewable green energy technology.

Boom in Anaerobic Digestion Scotland as Food Waste Falls

New figures were published last week by the Anaerobic Digestion and Bioresources Association which show that Scotland's anaerobic digestion industry has grown by more than two thirds over the past year. Yes! The Scottish anaerobic digestion industry has grow by nearly seventy per cent in a year.

That is an amazing statistic and is probably a reason for the UK Goverment to have decided that maybe this industry no longer needs any taxpayer renewable energy subsidies.

Anaerobic Digestion News: 5 Undeniable Advantages of Anaerobic Digestion the...

Anaerobic Digestion News: 5 Undeniable Advantages of Anaerobic Digestion the...: The UK anaerobic digestion industry has done very well in recent years, with a huge growth in the number of AD Plants. But new UK government cut-backs in the longstanding support mechanisms for AD projects appear to be just the beginning.

Why is the UK government apparently set on abandoning AD, when it is a success story about an industry which deserves support far more than many others in the energy sector?

All we can think is that the UK government is cutting back on support for the industry, because it's not aware of the many compelling reasons why AD should be gaining more, not less, government support.

The advantages of anaerobic digestion are real, and substantial, and yet these benefits seldom, if ever, get the exposure they deserve.

Everyone who knows about AD should be reading these 5 benefits and shouting about them from the rooftops, and if you don't know about this we also recommend you follow this link (click on the header above) and read the article..

Major Energy Savings for Fully Mixed Anaerobic Digestion Plant Operators Confirmed by University Study


University Study reveals more methane and major energy savings for AD operators with Landia’s GasMix digester mixing system

The University of Aarhus has revealed important findings from an extensive study into the performance of Landia’s externally-mounted GasMix system, showing that it increases methane production by almost 11% in a digester treating agricultural residues.

The study also showed that viscosity was decreased by more than 31% when Landia’s GasMix was used in a heat exchange tank treating agricultural residues prior to anaerobic digestion.

This greatly reduced viscosity input from the heat exchange tank allowed for a 12.5% reduction in downstream reactor mixing times, equivalent to a saving of 210 kWh per day in electrical consumption.

Conducted partly at the Madsen Bioenergi plant in Skive, which every day treats approximately 285 tonnes of cattle/pig slurry, deep litter manure and maize silage, the Study also looked at the LBT Agro biogas plant near Hjørring – as well as the Energi Viborg Spildevand A/S wastewater treatment plant near Viborg (all three plants are in Jutland, Denmark).

Steen Buhl Larsen, Landia’s Managing Director, commented:
“Our GasMix customers have repeatedly informed us of significant increases in their site’s gas yields – and now we have a detailed Study – painstakingly compiled over several months - to show just that” 
He added:
“AD operators have a golden opportunity to produce more gas, yet at the same time, dramatically reduce their energy consumption. These factors are in addition to the fact that because everything is outside the tank, GasMix is much easier to service, with no downtime”. 
Using a unique combination of gas and hydraulic mixing principles to provide efficient mixing of tanks, Landia’s GasMix is already installed at numerous AD plants worldwide, including the UK, Denmark, Germany, China and the U S, where it is also proving to be ultra-reliable. Established in 1933, Landia designed GasMix with the chopper pump (it invented in 1950).

External knife blades reduce particle sizes in a conventional hydraulic mixing method, whereby material is drawn from the bottom of the tank by a centrifugal pump. In this hydraulic mixing mode, the material is pumped back into the tank base through the jet nozzle, a tube that is narrower than that on the upstream side of the pump.

This ensures that the material enters the tank at high velocity, causing a vigorous mixing of the tank contents, including heavy material such as stones that typically tend to accumulate at the bottom of these tank designs. Landia’s GasMix also operates in a second mode of mixing. Here, the centrifugal pump output is diverted upwards to an injection nozzle located in the wall of the tank. Before the slurry from the centrifugal pump enters the nozzle, a pipe from the gas headspace in the top of the tank is connected at a right angle to the slurry pipe.

This allows headspace gas, in particular biogas when the tank is used as a digestion tank, to be drawn into the slurry stream by the venturi principle.

 *The Study was undertaken by Alastair James Ward, Adjunkt, Institute for Ingeniørvidenskab, Aarhus University, Denmark.

Up to £10k Anaerobic Digestion Grant for English Farmers

Thinking about starting a biogas (Anaerobic digestion) plant on a farm in England? Then check out this article by following the link to see if you qualify:


"The On-farm Anaerobic Digestion Fund offers farmers in England a grant of up to £10,000 to undertake a feasibility study and business plan to investigate the potential of AD on their farm. 
 The fund also offers capital loans of up to £400,000 (or a maximum of 50% of the capital cost). To be eligible for the fund, the AD plant must be fed predominantly on farm wastes such as manures and slurries and have an output of less than 250kW. 
The fund is open until 31st March 2016 and applications for grants and loans are assessed on a rolling basis."
