  • The Plasma Processing of Steel Plant Wastes

    ABSTRACT: Electric arc furnace (EAF) dusts, have been successfully treated in plasma-fired carbothermic reduction furnaces to recover metal values. Although the technology is equally applicable across the range from plain carbon to stainless steels, historically, it is the latter that has been the more commercially successful. Because the plasma heat source is independent of process chemistry, ...

  • Plasma Methods for Technology Processing of Toxical Industrial Wastes

    Experimental study of thermal neutralization of some toxic chlorine and bromine industrial wastes, as well as of pesticides with a expired term of validity was carried out in the three-jet plasma reactor . Different physical-chemical methods were used for analysis of products of waste processing. It was shown that plasma technology provides effective processing of toxic ...


  • Waste to energy – processing waste with a high thermal value to substitute combustibles

    With the taking effect of the TASi (Technical Regulations on Estate Waste) in 2005, non-treated waste must no longer be disposed of and deposited. Commercial and industrial residues with a high thermal value such as rejects from paper industry, punchings from rubber and plastics, and other mono-fractions which are characterized by homogeneity and constant combustible properties through mechanical ...


  • Utilization of kaolin processing waste for the production of porous ceramic bodies

    The kaolin processing industry generates large amounts of waste in producing countries such as Brazil. The aim of this study was to characterize kaolin processing waste and evaluate its suitability as an alternative ceramic raw material for the production of porous technical ceramic bodies. The waste material was physically and chemically characterized and its thermal behaviour is described. ...

  • Anaerobic co-digestion of winery waste and waste activated sludge: assessment of process feasibility

    In this study the anaerobic co-digestion of wine lees together with waste activated sludge in mesophilic and thermophilic conditions was tested at pilot scale. Three organic loading rates (OLRs 2.8, 3.3 and 4.5 kgCOD/m3d) and hydraulic retention times (HRTs 21, 19 and 16 days) were applied to the reactors, in order to evaluate the best operational conditions for the maximization of the biogas ...

  • Waste in the Netherlands

    Household waste More than 10% of waste arisings in the Netherlands consists of household waste. The local authorities are responsible for collecting this category of waste. A set of rules compels the local authorities to collect separately organic household waste, glass, paper and board, textiles and small chemical waste. The policy aims at giving producers more responsibility for their products ...


  • Calcium Silicate Hydrate Triggered Phosphorus Recovery – An Efficient Way to Tap the Potential of Waste- and Process Waters as Key Resource

    The global economic situation requires the development of sustainable concepts, in order to provide potential recyclables from waste and to recirculate them to the cycles of matter. Considering furthermore the increasing limitation of global phosphate rock resources, the recovery of phosphate from various waste- and process waters is vitally important. Therefore, research has recently been ...

  • Seafood processing waste management and its impact on local community in Cochin Corporation, India

    This study utilised face to face survey method through semi structured interview schedule for gathering information regarding the quantity of seafood raw materials procured and the associated waste generation pattern, waste management issues and ultimately the impact excreted by the waste produced to the local community, in India’s one of the major seafood processing zone, the Cochin Corporation ...

  • Production boost for innovative PIM process

    A board product composed of a wide mix of recovered materials - including clinical waste and rubber crumb from used tyres - has been developed using the powder impression moulding (PIM) process. Although production commenced only late last summer, new capacity is already being added to cope with anticipated demand. And as Recycling International discovered, this is not the only product to be ...

  • Thermal plasma processing in the production of value added products from municipal solid waste (MSW) derived sources

    Abstract The disposal of Municipal Solid Waste (MSW) is an increasingly difficult challenge for communities. Advanced thermal treatment (ATT) technologies, such as Gasplasma®, have been specifically developed to effectively utilise wastes to generate clean electrical power. An added beneficial feature of this process is the conversion of ash-type materials in the MSW to ...

  • In-vessel cocomposting of green waste with biosolids and paper waste

    In comparison to traditional windrow composting, in-vessel composting techniques often represent more effective waste management options due to the reduced production of bioaerosols and leachate and the potential for better process control. Chemical processes occurring during the cocomposting of three common wastes (green waste, biosolids and paper processing waste) were studied using the forced ...

  • Wood waste product

    A landfill needed a way to reduce their waste stream volume, increase the life of their landfill, and recover a recyclable, marketable product. Wood and yard waste material comprise up to 20% of their entire waste stream volume. Processing and recycling this material will extend the life of the landfill by 20 years. They chose WSM's Model 4864BH Horizontal Hogging System with a customized feed ...

  • Municipal waste management & handling

    Several MSW management practices, such as source reduction, recycling, and composting, prevent or divert materials from the wastestream. Source reduction involves altering the design, manufacture, or use of products and materials to reduce the amount and toxicity of what gets thrown away. Recycling diverts items, such as paper, glass, plastic, and metals, from the wastestream. These materials are ...
