  • Alternative stabilisation options of mechanically sorted organic fraction from municipal solid waste prior to landfill disposal

    In order to foresee the measures of the Directive 1999/31/EC, waste management policies are focused on the reduction of organic matter landfill disposal, through the recovering of the organic waste stream or the pre-treatment of residual wastes before landfilling. This paper discusses the advantages and disadvantages of possible stabilisation treatments of the mechanically sorted organic fraction ...

  • Co-digestion of press liquids of source-sorted municipal organic waste in anaerobic sludge treatment of municipal wastewater treatment plants

    This paper describes a semi-continuous laboratory-scale investigation of a potential co-substrate for mesophilic anaerobic sludge digestion in a municipal wastewater treatment plant. A feed liquid produced from source-sorted municipal organic waste by pretreatment with a screw press was subjected to the investigation. Quantities produced in press trials as well as the composition of the feed ...

  • Mesophilic and thermophilic anaerobic digestion of source-sorted municipal solid waste

    A change in existing collection systems for household waste is presently in progress in many Swedish municipalities. The objective is to separate the decomposable fraction from non-biodegradable waste in order to facilitate biological treatment and recycling of nutrients. The main reason for this development is the effort to replace landfilling of nutrient-rich, wet organic waste with sustainable ...

  • Rest or mixed waste sorting-digestion-separation for the recovery of recyclables and energy

    Source separate collection of biowaste has been implemented in many countries in Europe, especially in the German- speaking countries and the Benelux. By separating the biowaste fraction, a waste fraction called rest waste or grey waste is left over. This fraction is in most instances landfilled or incinerated. However, rest waste still contains a considerable amount of organics (up to 65%) which ...

  • Operator Strategies : Sorting Out the Plastic

    BETTER BUGS Ideas and products in the Better Bugs category attempt to affect the biological components and biochemistry of processes by altering the mix of microorganisms or enzymes present. After all, biology is the foundation of many, if not most, organics recycling systems. Pyrophiles: The first example of Better Bugs involves pyrophilic organisms, bugs that can take the heat. This example is ...

  • Thermophilic two-phase anaerobic digestion of source-sorted organic fraction of municipal solid waste for bio-hythane production: effect of recirculation sludge on process stability and microbiology over a long-term pilot-scale experience

    A two-stage thermophilic anaerobic digestion process for the concurrent production of hydrogen and methane through the treatment of the source-sorted organic fraction of municipal solid waste was carried out over a long-term pilot scale experience. Two continuously stirred tank reactors were operated for about 1 year. The results showed that stable production of bio-hythane without inoculum ...

  • A Comparison Between Systems for Source Separation of Organic Household Waste

    Conventional collection of source separated waste using separate containers was com-pared to collection in bags with different colours and optical sorting (OptiBag). Purity was found to be high, especially in the OptiBag system. However the conventional system had new instructions for sorting, which may have influenced the result. Sources for heavy metals are identified as waste metal fraction, ...


  • Sorting and Recycling Municipal Solid Waste (MSW) in Xiamen City, China - Case Study

    TOMRA Sorting Recycling is playing a pivotal role in the implementation of automatic sorting at the MSW plant in Xiamen Background The city of Xiamen, renowned for its natural beauty, is located on China's southeast coast, in Fujian Province. Its famous seascape and clean natural environment are a magnet for tourists, and the city government wants to keep things ...

  • EnviroSolutions, Inc. Responds to Increased Popularity of Organic Waste Recycling

    Most Americans are well aware of the concept of recycling and why it is important to the future of the planet. Government agencies and environmental groups have long stressed the need to place more waste into the recycle bin and less into the trash container. From paper to plastic and everything in between, “single-stream” recycling has grown in popularity in recent years. Also known ...

  • Organics cart and container trends

    WHEN it comes to figuring out what cities, states and provinces are still throwing away, food residuals from households, commercial businesses and institutions continue to top the list. And as more jurisdictions look to adopt Zero Waste goals and mitigate methane emissions from landfills, the obvious candidate to boost diversion rates is the food residuals stream. In cities and towns that already ...

  • 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 ...

  • Preparing the way for commercial organics recovery

    The Planning for a source-separated commercial organics program began in California's Santa Cruz County in 2001. Businesses were surveyed to determine if there was sufficient interest in separate collection of food, food-soiled paper and wax-coated cardboard to supply a collection route. Many restaurants, markets and residential facilities responded enthusiastically to the idea of collection and ...

  • Treatment of Alkali-Pretreated Slurry of Organic Fractions of Municipal Solid Waste using Upflow Anaerobic Sludge Blanket (UASB) Reactor

    [Master's Thesis in Environmental Engineering] As an alternative technology for use of local governments, we propose to demonstrate the suitability of anaerobic digestion (AD) system to treat the organic fractions of municipal solid waste (OFMSW). To enhance the process, we applied several pre-treatment steps: comminution, extraction, and addition of sodium hydroxide to achieve the desired pH ...


  • San Francisco Expands Commercial Organics Recycling

    In San Francisco, commercially generated organics (primarily food residuals) are being diverted from the landfill through a variety of programs with different types of generators, collectors and processors/markets. These efforts include: Redistribution of edible discarded produce and other food, including prepared foods from restaurants; conversion of food processing waste and inedible produce ...

  • 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. ...
