  • Biosolids ban struck down

    In 1994, Los Angeles County Sanitation Districts (LACSD) bought a 4,700-acre farm (called Green Acres Farm) in southwest Kern County for the purpose of land applying biosolids from its 11 wastewater treatment plants. LACSD land applied 800 wet tons/day at this site for several years. In 2006, Kern County voters passed Measure E on the ballot with 83 percent approval. This measure banned ...

  • MSW Management: Safely Countering the Rise of Landfill Odors

    One of the core challenges of landfill and compost site management is fighting the rise of foul odors. In addition, as communities expand further out from previous areas, they eventually become neighbors to landfills – calling for a comprehensive odor-control approach to countering odor complaints. In fact, compared to other industrial applications such as wastewater treatment and asphalt ...

  • Comparing nonreinforced and internally reinforced GCL

    Water is one of the most destructive forces on the planet, eroding everything from continents to human-made wonders. Water is also a vector by which contaminants spread from landfills and other waste reservoirs. Therefore, creating effective water seals has been a top concern in construction. For many years, factory-fabricated clay products have been the barrier of choice against water and other ...

  • 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 ...

  • Valuable Products From Tannery Wastes

    Abstract We proved the viability of enzymatic dechromation technology, proceeding under mild reaction conditions, by the daily capacity of 3 metric tons for processing chrome shavings. The advantage of the enzymatic reaction is producing protein hydrolyzates of relatively good quality and chrome sludge. The quality of both is increased by using organic bases to form an alkaline reaction mixture. ...


  • Making commercial product from waste

    County Tyrone-based CDE Ireland Ltd, specialists in the design and manufacture of tailor-made processing equipment for the sand and aggregates industries, have recently installed a complete new processing system for Liam Lynch (Quarries) Ltd’s limestone quarry in Croom, Co. Limerick.The system includes Ireland’s first overhead-beam GHT filter press, which recycles the maximum amount ...

  • Sunflower seed waste as lightweight aggregate in concrete production

    The Effects of Sunflower Seed Husk (SSH) as aggregate replacement materials on concrete properties were investigated using different amounts of physical and mechanical properties. Concrete of 300 and 400 dosages was produced by adding various amount of SSH (5, 10, 20 and 30%). The replacement of SSH dramatically reduced the unit weight, compressive strength, splitting tensile strength and ...

  • Investigation of benefit of using coal wastes in cement production

    Waste disposal in coal preparation plants leads to serious environmental problems. These wastes usually contain about 20% carbon, and the composition of the remaining ash is similar to clay. Addition of these wastes to cement clinker raw material utilises carbon as a source of energy. In this investigation, the effect of addition of these waste materials to the raw materials used in cement ...

  • Bio hydrogen production from kitchen waste

    The hydrogen producing organisms such as Escherichia coli (E.Coli), Enterobacter cloacae, Hafnia alvei, Citrobacter freundii, Serratia marcescens and Clostridium acetobutylicum strains were isolated from the sludge of biogas plant. The hydrogen producing efficiency of isolated organisms from kitchen waste were examined under anaerobic conditions. Lab scale studies were conducted under controlled ...

  • Automotive Shredder Residue (ASR) - From Waste to Products

    The paper will explain WESA-SLF, a dry-mechanical process to treat ASR with the aim to achieve usable products, mainly organic materials, metals, and minerals. Detail information will be given about the first plant for processing 4 tons per hour ASR which had its start up end of 1999. The experience with the first months in operation as well as with the quality of the products and the influence ...

  • Food manufacturers: Include waste in final cost of product

    Over the past year, the momentum of food waste reduction has become a forefront concern on a global, national and industry level.
