  • Gasplasma transformation of waste streams

    The Gasplasma process developed by Advanced Plasma Power is an advanced thermal conversion (ATC) technology which has been developed for the treatment of a wide range of organic and inorganic wastes, including household wastes, hade wastes, wastes derived from landfill, and biomass. These wastes can comprise solid, liquid or gaseous wastes either singularly or in combination. The core Gasplasma ...

  • Treatment of Oily-Waste Process Streams

    Standard oily-wastewater remediation relies on API 650 for oily-wastewater separation (O/W/S) treatment using gravimetric lagoon separation, then reprocessing the recovered floatable slop oil, followed by chemical flocculation, then reprocessing the recovered oily sludge, followed by dissolved air flotation (DAF), then using holdingpond clarification of supernatant wastewater, before ...


  • Waste stream utilisation for sustainable viticulture

    ABSTRACTField trials were established at four vineyards in January 1999 to evaluate the effects of four mulch mixtures on different soil and plant parameters. Mulches were made from wine industry and other commercially available plant and animal wastes. Soil, grape petioles, grape leaves and grape juice were analysed over three seasons. The mulches applied released considerable quantities of ...

  • Baseline Projections of Selected Waste Streams

    Abstract Waste represents an enormous loss of resources both in the form of materials and energy. Indeed, quantities of waste can be seen as an indicator of the material efficiency of society. Waste generation is increasing in the European Union, and amounted to about 3.5 tonnes of solid waste per person in 1995 (excluding agricultural waste) 1 Excessive quantities of waste result from: ...

  • How to make top-down and bottom-up sustainability converge

    Fits and starts are all too common in the sustainability world. One year you have budget for initiatives; the next you don’t. Management hails cost savings on individual projects, but they miss the big picture and fail to link progress across departmental boundaries. Bottom-up progress and top-down directives pass each other like proverbial ships in the night. But it doesn’t have to ...

  • Several waste gas streams: Highly contaminated oxygen-free waste gas, and medium waste gas stream - Case Study

    Example: Chemical industry Similar tasks: Petrochemical and pharmaceutical industries A producer of synthetic rubber creates a medium waste gas as well as a highly contaminated oxygen-free waste gas which contains primarily low hydrocarbons. The main waste gas stream is purified in a regenerative thermal oxidiser (RTO), while the oxygen-free waste gas passes through ...

  • Investigation of the household hazardous waste stream in a Hellenic municipality

    Hazardous waste (HW) in small quantities generated by households is often dumped into the mixed household waste. A variety of chemicals was recorded during a field research presented in the present paper. Aspects analysed in this work contribute to the categorisation of household hazardous waste (HHW) and quantification of them since lack of generation and composition data was noted in Greece. ...

  • Making India`s waste streams sustainable

    MIT researchers are developing a decision-support tool to help cities in India sustainably manage the societal and environmental impacts of their waste. The massive Deonar dumping ground in Mumbai has become the most visible emblem of an increasingly serious nationwide problem for India: what to do with its trash. Deonar’s towers of garbage are ...

  • 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 ...

  • Treatment and Disposal of Air Pollution Control Residue

    What is APCr? Thermal waste management using Energy Recovery Facilities (ERFs) is now a well-managed and mature technology that is subject to environmental monitoring by a range of competent international bodies. These ERFs have been established as a means of diverting waste away from landfill disposal and for valorising the material and energy content of the waste. Counter to historic ...

  • What Is Zero Liquid Discharge and How Does It Work?

    Not every industrial facility that produces wastewater will require zero liquid discharge (ZLD). It is usually looked to as a last resort because it can be a complex process that requires a high initial investment. If a facility is located on a site that has severe water scarcity issues and/or astronomical discharge fees, it might be ...

  • Tire Shredding: The Best Alternative

    From cars and trucks to planes, tractors, and forklifts, tires are used for a wide variety of vehicles. And those tires don’t last forever. Regardless of how many miles a tire travels, it should not be used longer than ten years past its manufacture date, as the rubber will grow brittle and can crack. This isn’t usually a problem, though, since most tires are replaced within three or ...

  • Does your facility need Zero Liquid Discharge Technology?

    If your industrial facility discharges its waste into deep wells, streams, sewers to publicly owned treatment works (POTWs), and/or other waterways, it is likely there are some types of regulations on discharging the waste. With an increasing push toward environmental protection, many industrial facilities and effluent regulators are strengthening strategies to reduce industrial process waste. ...

  • New ways for Metal Recycling

    REWAVE XRF 3-way-sorting in innovative  “Free-Fall”-design Recycling of metal and aluminium knows no limits because it can be remelted as scrap indefinitely. Metals, however have to be separated from non-metallic impurities, and different metals have to be sorted in pure fractions to be used as secondary raw materials substituting primary resources. Especially when it ...

  • Steel waste streams associated with decommissioning offshore structures in the Gulf of Mexico

    The weight of an offshore structure is an important factor in design and is closely linked to its fabrication, installation, and removal cost. Weight comparisons between structures are difficult to make, however, because many interdependent and unobservable factors influence its determination. In this paper, we develop first-order approximating weight algorithms for offshore structures in the ...

  • Jail waste streams provide unusual challenges to typical industry equipment

    Arlat ‘TS’ Filter Screen proves itself equal to the challenge. Unusually high volume of solids and the wide variety of materials in waste streams from correctional institutions provide unique challenges to today’s typical wastewater equipment. In recent years, the state of Virginia has installed five ARLAT ‘TS’ Filter Screens in correctional institutions. They use the screens to remove ...

  • Single stream waste sorting plant for MRF, England - case study

    Customer Grundon Waste Management Ltd. is the largest privately owned waste management company in the UK. The company was founded in 1929 and has moved into landfill operation, waste collection, and most recently into harnessing energy from waste.

  • Quantifying the impacts of co-digesiton of waste streams with sewage sludge

    In order to slow down the impending impacts of global climate change due to consumption of fossil fuels, governments are looking at ways to develop and incentivise alternative renewable energy sources. Subsequently, the UK has imposed renewable energy targets of 15% of all energy consumption by the year 2020, but admit that – in order to meet carbon dioxide reductions of 20% by 2020 – renewable ...

  • Turning Carbon Emissions Into A Revenue Stream

    On the heels of the EPA’s new carbon rules proposed by President Obama on June 2, I wanted to take a closer look at a potential disruptive technological breakthrough: taking CO2 waste streams and turning them into saleable, value-added feedstocks. Certainly, the deployment of renewables, energy efficiency, smart grid, and energy storage technologies offer some of the most cost-effective ...
