  • Busting Biomethane Myths

    Over the past few years, more and more companies have woken up to the financial and environmental benefits to be gained by making the most of their organic waste streams. In fact, the anaerobic digestion (AD) industry – which converts millions of tonnes of food, sewage and farm waste into renewable energy (biogas) and biofertiliser – has been one of the UK’s biggest success ...

  • Crumbling Concrete Water Networks Linked to Common Water Treatment Additive

    Concrete distribution and sewer networks are being corroded at an alarming rate partly because of a commonly used additive in the domestic drinking water and wastewater treatment process according to published reports in the journal Science. In countries throughout the world from industrialized nations like Australia and the USA to developing nations like Colombia, Ghana and the Philippines, the ...

  • Converting waste into valuable resources with the Gasplasma process

    Abstract This paper reports on a novel process development to convert waste into renewable energy using gasification. Advanced Plasma Power (APP) has developed an advanced thermal conversion technology, (Gasplasma ), capable of treating a wide range of organic and inorganic wastes. In the two-stage thermal process, the fluidised bed gasifier (FBG) converts the waste to a crude syngas ...

  • 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 ...

  • 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 ...

  • Digester Developers Target Mixed Organic Waste Streams

     emerging group of commercial companies see a viable business opportunity in North America around building, owning and operating larger scale anaerobic digestion (AD) facilities to process mixed organic waste streams. In some instances, the projects being proposed and constructed only include anaerobic digester operations. In others, there is a combination of digestion with back-end ...

  • New system to convert food waste into fertiliser for greenhouse use gives potential 95% reduction in CO2 emissions

    A new method of processing food waste into fertiliser has been outlined in a recent study. The process uses a digester system with microorganisms to break down organic waste into fertiliser. The resultant fertiliser was used in a low-energy greenhouse to produce a range of food crops. The method is a potential way to utilise food waste and reduce the energy consumption of food production as part ...

  • Pumps with extended service life for generating biogas from organic waste

    When regular commercial pumps are used to process organic waste, they typically wear out after only a short period of time. Liquids pumped under these conditions attack pumps from two different angles: first with highly abrasive additives and second with liquids that have highly fluctuating pH values and therefore a high level of chemical aggressiveness. These conditions are very tough on seals ...

  • Composting Process and Organic Fertilizers Production

    Illustrated explanation of two broad stages that are usually applied in most composting facility. First, composting process that convert raw compost into mature compost. Second, organic fertilizers production that convert mature compost into granulated fertilizers. Feedstock for composting stage can be farm and animal husbandry wastes, biomass from plants, and biodegradables that have been sorted ...

  • Management of waste organic matters and residential used water for culture and biomass production of red worm (Tubifex tubifex)

    The efficacy of red worm (Tubifex tubifex) for converting organic wastes like pig dung, poultry excreta and dairy sludge into worm biomass production was investigated. For this purpose, three experiments each for pig dung, poultry excreta and dairy sludge were conducted in cement trenches for 90 days duration. The poultry excreta produced maximum biomass (126.53 ± 2.16 g), followed by the ...

  • Presence and survival of fungi and clostridium Tyrobutyricum during anaerobic treatment of organic household waste

    Today the anaerobic microbial process of biogas formation is more into focus than ever. This interest is due to the fact that is offers the community means of fulfilling several obligations: treatment of organic wastes, recirculation of nutrients between urban and rural areas and production of renewable energy. Presently, several Swedish cities have built centralised biogas plants, treating ...

  • Composting Key to Meeting Landfill Organics Ban

    The Halifax Regional Municipality (HRM) in Nova Scotia took a giant leap in 1998 to reaching a 50 percent diversion goal by 2000. Between July and November, 1998, organics collection carts were distributed to almost 100,000 households in the region. In December, two new composting facilities designed to process those materials, as well as feedstocks from the commercial sector, opened their doors. ...
