  • On the Dynamics of Recycling and Natural Resources

    We study the dynamic impact of recycling through its effect on the production set of the economy and its relationship with natural resources. The contribution of renewable and recyclable resources for sustainability is studied. Although in the short run recycling may alleviate resource scarcity, in the long run it is not enough to compensate for the exhaustibility of non-renewable resources and ...

  • An interdisciplinary approach to the assessment of water recycling technology options

    Whilst work on the development of engineering options for water recycling has continued apace over the last decade, less attention has been paid to the problem of selecting appropriate technologies for particular applications. This paper firstly reviews the motivations for a cross-disciplinary approach to technology selection in this context, highlighting the process of translating research ...

  • 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 ...

  • Diaper recycling

    Today, more than 96 per cent of parents use disposable diapers (verses cloth) due to convenience. A child in diapers will generate approximately one tonne of diaper waste prior to being toilet trained. The Sierra Club estimated that 18 billion disposable diapers are generated annually in the United States, using up four per cent of landfill space (according to U.S. EPA). The Greater Toronto Area ...

  • Environmental management: An agenda for action

    A business agenda for sustainable development is described, where the main thrust is to be the manufacture of durable and recyclable goods by processes which minimize the production of waste and polluting emissions. This is to be achieved through education, research and innovation with a more open dialogue between producers and society.Keywords: recycling technology, sustainable development, ...

  • Ammonium removal from wastewater via struvite pyrolysate recycling with Mg(OH)2 addition

    Magnesium ammonium phosphate (MAP) pyrolysate recycling technology was investigated with Mg(OH)2-mediated pyrolysis. The results revealed that the removal ratio of ammonium was stable at about 75%, and could be increased to 79% after additional acidolysis. The phosphate concentration in the supernate was low at 2 mg/L. The optimum conditions for ammonia release were a 1:1 molar ...

  • Acid recycling in steel pickling plants: state-of-the-art and new developments in environmental protection

    For acid pickling of heat-treated mild steel and steel products for up to the middle of the last century, sulphuric acid was primarily in use, which has been replaced since the 1960s stepwise by hydrochloric acid. During this time, also the pickling of high alloyed steel with hydrofluoric acid or mixtures of hydrofluoric acid together with nitric acid has been applied on industrial scale. The ...

  • Brief Introduction of Plastic Recycling Technology

    Plastic recycling and disposal of solid waste of plastics use petroleum and coal as raw materials to produce plastics instead of natural macromolecule materials. It has gone through a difficult process, and a whole generation of outstanding chemists have worked hard to achieve the excellent physical and chemical properties and durability of plastics. Plastic has replaced a large number of ...

  • The value of fracking wastewater treatment and recycling technologies in North Dakota

    The oil boom in North Dakota is aided by hydraulic fracturing, often referred to as fracking. Fracking uses a pressurized water, sand, and chemical mixture to break through layers of rock and release oil and gas. This procedure produces hundreds of truckloads of wastewater for each fracked well. In this study, we analyze the financial feasibility of a system of wastewater recycling and reuse to ...

  • The role of information technology and systems in reverse logistics: a case study

    Reverse logistics is a process whereby a manufacturer accepts products from consumers for possible remanufacturing, recycling, reuse or disposal. Recovery of used products is receiving increased attention due to growing environmental concerns. Though studies have shown that reverse logistics practices can result in substantial cost savings for companies, there has been some reluctance ...

  • Urban-Water Harmony model to evaluate the urban water management

    Water resources in many urban areas are under enormous stress due to large-scale urban expansion and population explosion. The decision-makers are often faced with the dilemma of either maintaining high economic growth or protecting water resources and the environment. Simple criteria of water supply and drainage do not reflect the requirement of integrated urban water management. The ...

  • Pre-shredders from Erdwich reduce up to eight tonnes of electrical and electronic scrap per hour using two drives, each with a power of 40,000 Nm

    The handling of electrical appliances has changed drastically over the past 20 years: Nowadays, a defect appliance is replaced rather than repaired. According to United Nations' estimates, 40 million tonnes of electrical and electronic scrap is produced per year worldwide, which will be doubled by 2025. Valuable resources such as steel, nonferrous metals, plastic materials etc. can be recovered ...
