  • 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. ...

  • 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 ...

  • Composite construction products from waste tyres

    The construction industry consumes approximately 420 million tonnes of products per year, and therefore utilises large quantities of raw materials. Alternatives to primary materials in construction products are already widely used; examples include the use of construction and demolition wastes as aggregates, timber wastes in composite board products and by-products from steel-making in the ...

  • Chemical production and characterisation of activated carbon from waste 'coffee grounds'

    Activated carbon was prepared from ground–coffee in this study. Experimental results reveal that for the ratio (0, 1 ÷ 0, 3) of coffee grounds to activating agents (ZnCl2, H3PO4) has not noteworthy influence. The rise temperature and carbonisation time respectively, in the interval of 500–700°C and ...
