UK Biofertiliser Certification Scheme for Digestate Success or Failure

There has a been a slow take-up of digestate certification for bio-degradable organic waste with only 8 AD Plants now certified under the scheme, albeit 5 of those being so far during 2012.

The question has to be asked whether a viable market for source-separated biodegradable waste derived digestate will ever be achieved for this undoubtedly high nutrient and excellent soil improvement value fertiliser?

The problem for all Anaerobic Digestion Plant operators in the municipal waste management sector of the industry has always been that the digestate produced by them is classified as a waste. Being a waste, it cannot be freely marketed as a product in the normal way. So, there is effectively no way for the producers to generate a revenue stream from their digestate. In fact in many cases their entire digestate production may need to be treated before it can be disposed of. Such treatment, which is done in a water treatment plant sometimes by sewer discharges for the smaller plants, is very expensive indeed.



Anyone using the none Biofertiliser Certification Scheme compliance accredited digestate on farmland must comply with stringent waste management regulations. Such regulations, even where digestate use is feasible, brings high costs and also puts off potential users. After-all, how many supermarkets would be happy to see their produce if described as fertilized by an industrial waste?

The big hope has been the Biofertiliser Certification Scheme, and the hope that it would eventually be extended to other digestate sources. Read more about this at the Anaerobic Digestion News blog.

Full Steam Ahead for Valveforce’s High Pressure Valves at AD and Biofuel Plants

Steam system and flow control specialists Valveforce has launched a new range of Control Valves ideally suited for AD Plant Applications.

Valveforce
Valveforce is the new name promoting valves for Anaerobic Digestion Plants. The UK Midlands valve specialist is offering a technical valve design service for biogas plant valving from its fresh new website, and offers to match AD plant designer's requirements with its valves, supplied by companies such as Chemvalve-Schmid, Clorius, Gestra, Leser, RTK, Sart, Somas and their own-brand "Valveforce".

In their news release they have announced that the newly launched range is now available, providing High Pressure Two-Way, Pneumatic and Electric, Control Valves, which have been specifically designed to aid and maximise efficient operation of the energy centre role of biogas and biofuel plants.

Valveforce undertake to use their reported staff skills of with over 30 years of experience design, to build and test high quality bespoke valve systems. But, where clients have less complex requirements they also provide off-the-shelf solutions.

Valveforce Safety

Valveforce have also ensured that these new High Pressure Valves will provide safe control in the special AD environments seldom encountered elsewhere.

Described as having been designed in a "straight through globe style with precision cast bodies for maximum capacity", Valveforce’s High Pressure Valves can handle a wide range of fluids found at renewable energy and fuel plants, including water, thermal oil, steam, nitrogen and natural gases.

For quick change and ease of maintenance, these new valves are in optimised modular construction and benefit from a large range of actuators, again as experience has shown to be needed to provide for the wide diversity of duties commonly found at AD/biofuel plants.

In addition to its High Pressure Two-Way Pneumatic and Electric Valves, Valveforce is also supply Mixing and Diverting Valves, as well as Severe Duty Valves for biogas and biofuel applications.
