EDG to support Dutch company with construction of biogas plants that recycle minerals and produce commercial NPK fertilizers
Swiss Hawk’s portfolio company, Enviromental Development Group AG (EDG), has annouced [*German] the closing of an agreement with Dutch company Beesterzwaag Beheer B.V. to support the construction of advanced biogas plants that recycle minerals and produce high-quality commercial fertilizers from digestate in a highly efficient and integrated way.
Beesterzwaag is a technology leader in the field of converting biomass feedstocks used in energy production into NPK fertilizers, with a patented technique that allows a sustainable handling of agricultural waste derived from the livestock and farming sectors. It is often said that biogas digestate or biomass ash 'can be used as organic fertilizers', but merely spreading these materials onto farmland is not efficient and does not allow for precise control of dosages.
Instead, Beesterzwaag developed a process (schematic, click to enlarge) that concentrates part of the digestate into into pellets that are then used as a biofuel for power generation. After the pellets are burned, the remaining minerals are recovered and reused. The other fraction contains ammonia, which is transformed in a green way into ammonium nitrate, the world's most widely used fertilizer. The result is a commercial liquid NPK fertilizer containing the macro-nutrients used in agriculture.
The process consists of the following steps:
sustainability :: biomass :: bioenergy :: biofuels :: biogas :: anaerobic digestion :: waste :: fertilizer :: minerals :: nitrogen :: Belgium :: Netherlands :: Germany :: Switzerland ::
Biomassa Holding B.V. is building the following large-scale biomass plants in the Netherlands and in Belgium: a 180,000 ton biomass plant in Drachten (energy for 10,000 households), a 135,000 plant in Terneuzen and a similar one in Nederweert (both supply energy to 7,500 households), a 120,000 ton plant in Ieper (6,600 households), a biomass plant with a capacity of 240,000 tons in Waalwijk (good for 13,300 households) and one with a capacity of 150,000 tons in Zaltbommel (8,300 households.
Enviromental Development Group AG plans to co-operate with Beesterzwaag in regard to building of an additional plant in North-West Germany. The investment volume totals approx €6 million. EDG has made an exclusive agreement with Beesterzwaag for the promotion of the technology in the German market, the world's largest biogas market.
EDG operates as a project developer in the field of environmental technologies and cooperates with established companies as well as with independent teams. EDG structures the projects by identifying and evaluating innovative technologies/ processes, structuring of projects and developing business plans, preparing projects for investment, creating synergies between the portfolio projects.
EDG focuses specifically on the utilisation of biomass (biofuel and biogas), wind and solar energy, 'waste-to-energy( (utilisation of recycling-and-disposal-technologies for the production of energy and secondary raw materials, smart technologies for energy and resouces efficiency.
Swiss Hawk is a niche investment banking organisation that trades in high growth alternative asset class investments. The Company pursues an aggressive investment policy focusing on late stage pre-IPO and IPO transactions with high growth potential and planned exit in the short to medium term. Swiss Hawk is listed on the Frankfurt Stock Exchange Open Market.

The other fraction contains ammonia, which is transformed in a green way into ammonium nitrate, the world's most widely used fertilizer. The result is a commercial liquid NPK fertilizer containing the macro-nutrients used in agriculture.
The process consists of the following steps:
- Centrifuge: the digestate is separated and concentrated by a decanter. The concentrate (thin fraction) contains the biggest part of nitrogen and potassium components of the minerals, while the concentrate (solid fraction) contains the biggest part of the phosphates.
- Drying: the concentrate from the decanter is fed to a dryer. The dryer is heated by the steam produced from the heat exchanger in the off gas of the gasmotors powered by biogas generated on-site. The dried concentrate will be pelletised and used as biofuel in coal or biomass fired power plant. The dryer is located in a separate room. The moisture from the dryer is condensed and used to produce hot water. The condensate is recycled to conversion process. The non condensables are treated before the are emitted.
- Pelletization: The biofuel is pelletised and transported to a container, ready to be shipped to power plants.
- Nitrification: The majority of the minerals in the concentrate (thin fraction) will be ammonia. The ammonia is converted to ammonium nitrite in a biological step. In a second step the ammonium nitrite is converted to ammonium nitrate by addition of acid and air. Ammonium nitrate is most used fertiliser in the world. The liquid out of the nitrification is called the thin NPK minerals fraction.
- Evaportation: the thin NPK minerals fraction output from the nitrification contains a still a lot of water. This thin fraction is concentrated in an evaporator into NPK fertiliser. The concentration of this fertilizer will be as high as the concentration of existing competitive liquid fertilizer products. The evaporator release condensed vapour besides the NPK concentrate. The concentrated NPK is stored in a tank and transported via trucks to the clients.
