  • 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 ...

  • Mixed waste composting trends

    It's been about 25 years since vendors started marketing systems to process mixed municipal solid waste via composting in the U.S. Today, there are 13 plants, most fulfilling their niche in the communities they serve - whether managing MSW in high tourism areas, or processing residual organics from materials recovery facilities. Table 1 provides summary data on the 13 facilities. While we did not ...

  • Plasterboard waste recovery from smaller building sites

    Most methods for recovering waste plasterboard from construction sites rely on it being segregated on site into adedicated collection container, such as a skip, bin or bags.  This can be difficult for smaller building sites where spacefor these containers may be limited, and the quantities of plasterboard waste are small thus reducing the costeffectiveness of recovery. However, many small ...

  • Liberating contaminants for easy recovery

    The number one challenge associated with most site remediation designs and methodologies is that 90-95 per cent of all environmental contaminants are present in an adsorbed phase onto soil and bedrock surfaces within both saturated and unsaturated zones. Contaminants, including hydrocarbons (LNAPL), chlorinates (DNAPL) and heavy metals, are sorbed onto the substrates and so have reduced mobility ...

  • An eco–sustainable model on energy recovery from municipal solid waste

    In the present day situation, the toxicity in municipal solid waste has increased to a very high level leading to various problems. The main purpose of the study is to improve the quality of mixed solid waste by adding locally available biomass. It was observed that the feedstock for refuse derived fuel and biomethanation contains 12% and 20% toxicity, respectively, as a result degrading the ...

  • Operation and recovery of a seasonally-loaded UK waste stabilisation pond system

    An intermittent discharge waste stabilisation pond system was trialled for treatment of a seasonal wastewater load from a campsite. The system showed rapid acclimatisation to incoming load, with chlorophyll-a exceeding 700 mg l−1 within 2 weeks and filtered and unfiltered effluent biochemical oxygen demand below 20 and 30 mg l−1 respectively. Good ...

  • Materials recovery from waste cathode ray tubes (CRTs)

    Executive summary ObjectivesThis is the second interim report of this project being carried out by ICER with support from Glass Technology Services. The project is examining potential markets for waste CRT glass. In this second stage five potential applications have been investigated, three for screen glass which does not contain lead and two for lead-containing funnel glass ...

  • Energy Recovery from Residual Waste by Means of Anaerobic Digestion Technologies

    ABSTRACT Anaerobic digestion (AD) is a natural process, spontaneously taking place in natural surroundings, such as marshes,bogs, paddies, or in cesspits, landfills, and dedicated digesters, used for the conversion of organic waste into a rich gas. Typical AD substrates are: manure, sewage sludge, high BOD wastewater, and – more recently - the organic fraction of Municipal Solid Waste (MSW), ...

  • Evaluation of resource recovery through a Waste-to-Energy plant operating with municipal solid waste

    On 1 December 1984, an inter-local joint enterprise agreement was entered into between the Alexandria Sanitation Authority and the Arlington Solid Waste Authority (the 'Authorities'). The Joint Enterprise was formed to design, construct, equip, test and operate a solid waste to energy facility having an installed capacity of 975 tons per day of mixed Municipal Solid Waste (MSW). ...

  • 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 ...

  • The effect of mixing conditions on anaerobic digester performance

    The basic principle of aerobic wastewater treatment is the conversion of some parts of organic matters to biomass and this causes production of excessive sludge in aerobic processes. This excessive sludge is withdrawn from time to time to prevent accumulation of biomass in aeration basin. In most cases, this sludge requires the stabilization before the dewatering and disposal. Different processes ...

  • Mixed MSW composting is steady as she goes

    Two new facilities came on line in 2006, while one ceased operation and a second is shifting to a new technology. Annual survey identifies a total of 14 plants. Part I STEADY-STATE may be the best phrase to describe the status of facilities composting mixed municipal solid waste in the United States. In fact, steady-state may be the best phrase to describe solid waste composting in general since ...

  • A novel technology for on-site cupric oxide recovery from cupric chloride etchant waste

    For on-site copper recovery in print circuit board factories, we propose a novel technology to obtain cupric oxide with a low content ratio of chloride from high chloride concentration waste, such as cupric chloride etchant waste. Our technology is designed to avoid formation of double salt and accumulation of cupric hydroxide. In the proposed method, etchant waste mixed with hydrogen peroxide ...

  • Automotive spent catalysts treatment and platinum recovery

    The recovery of platinum from spent catalysts was examined. Platinum leaching was studied considering particle size, temperature, solid–liquid and HCl/HNO3 ratio effects. Many elements together with Pt were taken from a mixed spent catalyst sample. The main components of the leach liquor were Pt (1.84 g/kg cat) and Fe (0.94 g/kg cat). Platinum was separated from the leach aqueous solution by ...

  • Is human excreta a waste?

    Every day a huge amount of excreta is being produced by human society and it is also considered one of the most unwanted waste/refuse of the society because of its nuisance and diseases causing characteristics. However, it is also utilised as a fertiliser and soil conditioner in several countries such as India and China. Presently most common sanitation concept is centralised treatment of human ...
