Contract for biogas upgrading plant

Ros Roca has signed a contract for the construction of a biogas upgrading plant in Altenstadt / Schongau, Germany. The client is the Erdgas Schwaben GmbH, that is already installing their third biogas upgrading plant within their service area. In the plant biogas from an existing biogas plant that is treating organic waste is upgraded into biomethane. The biomethane has natural gas quality and will be fed into a natural gas pipe next to the site. The plant will be feeding biomethane into the natural gas grid already in summer of next year. A high pressure scrubber technology that has been tested in other numerous large-scale plants will be installed. By the production and feeding of the biomethane into the natural gas grid a highest possible energy efficiency is guaranteed. A further biogas upgrading plant is installed in Luxemburg at the moment. There also biomethane is produced and fed into a natural gas grid.

Groundbreaking ceremony of the Naturgas Kielen biogas

   plant

On the 30th of October 2008 the groundbreaking ceremony for the construction of the Naturgas Kielen biogas plant took place. This occasion was honoured with a decent celebration by some hundreds representatives of politics, economy and media. The guests of honour included the minister of commerce, the minister of environment and the minister of agriculture from Luxemburg who especially emphasized in their speeches the commitment of the cooperative Naturgas Kielen and the innovative plant concept with the production of the renewable bioenergy source biomethane. Also the president of the cooperative Naturgas Kielen, Jean Berchem as well as the mayor of the city in which the construction site is located held a speech. The plant concept was explained to the guests in detail by Nico Godart, Naturgas Kielen     

Picture: official groundbreaking of the biogas plant in presence of the members of Naturgas Kielen as well as the ministers and the secretary of state of the Luxemburg Parliament.  

Just in time for the groundbreaking also the new homepage of Naturgas Kielen was finished (www.naturgaskielen.lu). The civil works have already begun and the biogas plant will be starting its operation already next year. Ros Roca installs the complete process engineering and will start-up the plant in the following. The biogas that is upgraded to natural gas quality will be fed into a natural gas grid that is located next to the construction site. The special thing about the plant concept is apart from the production of biomethane also the combined treatment of agricultural biomass with municipal and industrial organic waste.

Biogas plant in Lommel, Belgium in operation

The biogas plant in Lommel, Belgium started its operation at the beginning of this year. In the biogas plant waste from the potato processing industry are used for the generation of biogas. Both digesters with a nominal volume of 6.000 m³ each are in full operation and produce biogas. The biogas plant will produce approximately 12 mio m³ of biogas which will be used for the generation of electricity and heat. There is a direct connection between the productive manufactory where the heat energy generated from the biogas is used. With the heat energy from the biogas a large amount of fossil energy carriers can be reduced in the production in the future.

Press conference of the Association Naturgas Kielen

On November 20, 2007 the biogas project of the association Naturgas Kielen was officially presented during a press conference to the representatives of press, radio and television, in Kielen, Luxemburg. The biogas plant with a biogas preparation installation will be constructed turnkey ready by Ros Roca commissioned by the Association Naturgas Kielen. Natural Biogas will be produced originating from renewable energy sources, agricultural residues and biowaste, which will be fed into the existing natural gas line. The biogas plant produces approximately 3 Mio. m³ natural biogas reducing the usage of fossil energy sources and thus making an important contribution to the climate protection. As a further product a high-quality fertilizer is produced, that is directly used in the agriculture. Press releases can be found on the following link:

Ros Roca buys biogas treatment technology from Sweden

Ros Roca widened their product range for the biogas production and utilization and bought the biogas treatment technology from YIT, Sweden. Biogas treatment plants will be offered by Ros Roca and will be realized cooperating closely with YIT, the company that developed the procedure. The YIT procedure is based on the press water washing method and has already been successfully realized on various locations in Sweden for the transformation of biogas into natural gas quality. Since 2004 a YIT-biogas treatment plant is operating in Västerås, Sweden and is treating biogas from the biowaste digestion plant installed by Ros Roca. The treated biogas is used as fuel for municipal buses and private cars. By purchasing this technology Ros Roca is now able to offer the complete procedure chain of biogas production and biogas treatment turnkey including the feeding into the natural gas grid.

Further technologies for the densification and liquidation of treated biogas as well as biogas fuelling stations will also be offered by Ros Roca. Within the Ros Roca Group this know-how exists for many years in the IndoxCryoenergy. Numerous plants for the densification and the liquidation of natural gas have already been realized by IndoxCryoenergy.

Biogas plant officially inaugurated in Vienna

The biogas plant of the City of Vienna installed by Ros Roca as a general contractor was officially inaugurated on the 13th of September 2007 in the presence of numerous guests from the administration, politics and economy. Further information can be found on:

Ros Roca signs contract to install a major agricultural biogas

   plant in Luxemburg

The agricultural co-operative “Naturgas Kielen” that is composed of 30 farmers, recently commissionned Ros Roca to install a biogas plant with a biogas preparation in Kehlen, Luxemburg. The process technology of the biogas plant and the biogas preparation plant is delivered by Ros Roca turnkey ready. The consultancy firm se consult with its office in Luxemburg is responsible for the overall planning.

In the biogas plant agricultural waste such as liquid manure and dung, various energy crops as well as biowaste and organic industrial waste shall be introduced for the production of biogas. The Ros Roca biogas technology is very versatile and enables the treatment of extremely liquid substrates as well as substrates including solid material. Thus, in the biogas plant “Naturgas Kielen” a number of different substrates can be treated independently from the water content. The plant conception allows a modular construction and thus offers an extension of the capacity at a later moment, if further substrates are available. The plant capacity is 50,000 tons per year calculating with a biogas production of approximately 550 - 600 m³/h.

The scope of delivery by Ros Roca also includes a biogas preparation plant with which biomethane with a methane concentration of approximately 98% is produced from crude biogas. The biomethane is directly fed into the existing natural gas pipe close to the location. This biomethane with natural gas quality will be utilized as combustible for private as well as public gas heating boiler in co-generation units and will be utilized as fuel. By feeding the biomethane into the natural gas net a maximum energy efficiency can be guaranteed due to the fact that the energy recovery takes place exactly where it can be implemented with the highest effectiveness.  

The agricultural association “Naturgas Kielen” will be operating the biogas plant and will provide the substrates (energy crops, liquid manure and dung) necessary for the biogas production. Biowaste and organic industrial waste will also be treated in the biogas plant. At first, those will be fully automatically prepared and sanitized with a temperature of at least 70° C and a retention time of at least 1 hour according to EU-Sanitation Directive 1774/2002. After the digestion process the digestate substrate is separated partly into a liquid and a solid structure. The complete final product is distributed onto the agricultural area of the members and thus forms the closing link in the sense of the recycling management.

The planning activities of the biogas plant including the biogas preparation have already begun with se consult and Ros Roca. The biogas plant of the agricultural co-operative “Naturgas Kielen” is planned to start its operation already during the year 2009 and feed biomethane into the natural gas net of the City of Luxemburg.

Two new contracts to build digestion plants

Ros Roca signed two new contracts for the construction of digestion plants. In Alicante, Spain, Ros Roca will install a digestion plant for the organic fraction of household waste that is mechanically pre-treated. The digestion plant has an annual capacity of 52.000 tons and will start-up in already in the year 2008. This is already the nineth digestion plant by Ros Roca that is utilized in Spain for the biological treatment of household waste in a mechanical-biological waste treatment plant.

A further contract for the installation of a digestion plant was signed by Ros Roca in Sao Martinho du Porto, Portugal. The agricultural biogas plant will be treating an amount of 60.000 tons of pig manure starting in the year 2008.

Waste management world informs about the Ros Roca plant

The trade magazine Waste Management World informed – amongst other things - in the article: Biogas takes to the road: Sweden’s Växtkraft project shows the way ahead in detail about the digestion plant for the treatment of biowaste, renewable primary products and liquid organic industrial waste that was installed by Ros Roca as a general contractor.
