  • Reasonable waste digestion plants

    During the last years it became quite clear that in the area of utilisation of organic waste the anaerobic digestion has developed a leading position. This is not only based on its well known advantages:- abhigh rate degradation of organics- abcontained process- ablow emissions- abhigh yield of CO2-neutral produced biogas and high quality compost as its productsbut also on the fact that customers ...

  • Comparison of Capacity Factors in Anaerobic Digestion of Organic Waste in the UK

    The ranking was made based on the ratio between the gross electrical production of the plant during 2014 and the registered capacity of the plant under Renewable Energy Guarantees of Origin (REGO) scheme. The data on the electrical production of the plants is publically available through Ofgem  (The Office of Gas and Electricity Markets) which is responsible for the issuance of ...

  • Perspectives on organic waste recovery relative to composting and anaerobic digestion

    Generally speaking, organic waste renders its self suitable for recovery purposes owing to the nutrient elements it contains and the energy stored in the biochemical bonds of its constituent organic compounds. Both composting and anaerobic digestion (AD) have been used since a long time ago in reclaiming organic material. It seems that the first modern composting process was developed in 1920s in ...

  • Environmental efficiency of composting versus anaerobic digestion of separately collected, organic waste

    Environmental policy in the Netherlands among others aims at closing material cycles and minimising the amount of waste requiring final disposal. In this policy the highest priority is given to the prevention of waste production followed by (in descending order of preference) reuse, incineration with energy recovery and sanitary landfilling. In the implementation of this solid waste policy also ...

  • Co-digestion - Processes, potentials and organization Forms

    Co-digestion of organic wastes together with livestock manure has received growing interest in Germany during the last 5 years because some waste acts have been changed in order to achieve a better protection of the environment and to promote the utilisation of wastes for the formation of renewable energy and secondary products which can substitute mineral fertilisers and conventional soil ...

  • Enhanced anaerobic digestion of waste activated sludge of low organic content in a novel digester

    A novel digester, termed an internal circulation anaerobic digester (ICAD), was developed to intensify sludge digestion. It consists of reaction zone, settling zone, thickening zone, riser and downcomer. Internal circulation in the digester is intensified by backflow biogas. The mesophilic ICAD treating thermal pretreated waste activated sludge with volatile suspended solids (VSS)/suspended ...

  • Effect of organic loading rate on the performance of two-stage anaerobic digestion of the organic fraction of municipal solid waste (OFMSW)

    Two-stage anaerobic digestion of the organic fraction of municipal solid waste (OFMSW) was carried out: hydrolysis and acidogenesis in a continuous anaerobic hydrolytic leach bed (AHLB) reactor loaded at different rates (Bv = 3.8–7 gVSSL−1d−1) and methanogenesis of leachates, diluted with municipal wastewater in an upflow anaerobic ...

  • Case study - Procurement and installation of a Biogas desulphurization unit at the Chania WWTP

    A proposal based on Bioconservacion’s technology was selected as the winning bid in the public tender released in 2015, covering the design, procurement and construction of a biogas desulfurizing unit to be installed in the waste water treatment plant in Chania, Greece. With a population over 100,000, Chania is the second largest municipality in the Greek island of Crete. Its waste water ...

  • Anaerobic co-digestion of municipal organic wastes and pre-treatment to enhance biogas production from waste

    Co-digestion and pre-treatment have been recognized as effective, low-cost and commercially viable approaches to reduce anaerobic digestion process limitations and improve biogas yields. In our previous batch-scale study, fat, oil, and grease (FOG) was investigated as a suitable potential co-substrate, and thermo-chemical pre-treatment (TCPT) at pH = 10 and 55 °C improved CH4 ...

  • Treating organic waste with Cambi THP

    ABSTRACT This paper describes how the Cambi Thermal Hydrolysis Process (THP) treats biodegradable organic waste and converts it to renewable energy and pathogen-free and bio-fertilizer. The interest for the process is expected to increase due to new environmental legislation as well as increasing demand for renewable energy. The implementation of the European Landfill Directive 1999/31EC and the ...

  • Influence of the comminution of organic waste on their biodegradability

    Organic solids are present in very large quantities as products or waste from agriculture, food industry, household and many other fields. The disposal of organic waste can be realised using biological processes like anaerobic digestion or aerobic composting. The anaerobic digestion has advantages in comparison to composting such as a better handling of wet waste, the production of useful ...

  • Post-composting techniques of digested household waste

    Compost making is a method of recycling whereby organic waste is broken down to organic soil with the help of oxygen demanding microorganisms. There are different ways of making compost. Some require more labour and an exact procedure has to be followed; others neglect the precise procedure, which has advantages and disadvantages. Organic material, including toilet waste, can also be recovered to ...

  • `Hyperwaste Reduction` :Organics Recycling May Get Digested Look In Iowa

    CEDAR RAPIDS — with active support from the Iowa Department of Natural Resources (DNR) — is optimistic about its new strategy to expand organics recycling. Under the leadership of executive director Dave Hogan, the Bluestem Solid Waste Agency, which serves the Cedar Rapids region, is presently composting 118,000 tons/year of yard trimmings and paper/pharmaceutical sludges. But Hogan is convinced ...
