  • Zero Waste World - When the economy goes in circles, everybody wins.

    “Don’t let fashion go to waste,” says H&M, the global clothing retailer that booked $20 billion in revenues last year. So I brought a bag of old T-shirts, sweaters and khaki pants to an H&M store in Washington, D.C., where it took them, no questions asked, and gave me a coupon for 15 percent off my next purchase. H&M takes back clothes in all of its 3,100 stores in ...

  • Road Over Sensitive Groundwater Areas - Case Study

    When constructing or extending new roads, the responsible designers and contractors are increasingly faced with the task of preventing soil contamination. Therefore, measures for the protection of the groundwater are necessary in more and more cases. The corresponding requirements and specifications for such measurements are regulated in the "guide-line for constructional measurements of roads in ...

  • Vacuum evaporation treatment of digestate: full exploitation of cogeneration heat to process the whole digestate production

    Vacuum evaporation represents an interesting and innovative solution for managing animal waste surpluses in areas with high livestock density. To reduce operational costs, a key factor is the availability of an inexpensive source of heat, such as that coming from an anaerobic digestion (AD) plant. The aim of this study was to test vacuum evaporation for the treatment of cattle slurry digestate ...

  • It’s a ‘no’ to Pay-as-you-throw

    Axion Director Keith Freegard, recently spoke to Local Authority Waste and Recycling arguing against a Pay-as you-Throw scheme suggesting an element of ‘punishment’ could be counter-productive in increasing recycling rates. In my view, the Pay-as-You-Throw principle would not be a good idea because it is another example of trying to use a ‘stick’ to punish people for their ...

  • Denmark’s Near-Zero-Waste Wonder

    Has this Danish community found the formula for environmentally friendly industry? When we look closely at systems in nature — coral reefs or rainforests, for instance — we see something we don’t often see in human systems: mutually beneficial relationships and energy flows among the various elements, such as air, water, rocks, soil, and plant and animal life. If we ...

  • Is Waste Going to be Our Apocalypse Without a Noah’s Ark to Save Us?

    Human beings have been dumping waste in water, including the ocean, since before the Agricultural Age. The Industrial Age brought with it new materials to dump, chemical wastes and by-products. Some materials are dumped into rivers and find their way to the ocean by running downstream. Other materials are dumped directly into the ocean from boats. Plastic is a harmful pollutant that does not ...

  • Eccentric Disc Pumps Create Product Recovery Cost Savings

    As budgets tighten, operators of manufacturing facilities must implement new ways to meet established production quotas while spending less money. Improved operational efficiencies can critically affect the profitability of food and beverage, pharmaceutical, and cosmetic manufacturers, from the most basic productionline level through entire plant efficiencies, and even overall corporate ...


  • Waste plastic pyrolysis plant with high profits

    Pyrolysis Plant: Waste plastic pyrolysis plant, with the superiority of low capital investment and high fuel financial price, it has become the first preferred waste disposal method in many countries.This profitable project was established every week with low labor costs and high profits. Huayin renewable energy equipment company, established in 1993,have been a leader of oil pyrolysis ...


  • Anaerobic fermentation of organic solid wastes: volatile fatty acid production and separation

    Anaerobic fermentation of organic municipal solid waste was investigated using a leach-bed reactor (LBR) to assess the volatile fatty acid (VFA) production efficiency. The leachate recycle rate in the LBR affected the VFA composition of the leachate. A six-fold increase in the recycle rate resulted in an increase of the acetic acid fraction of leachate from 24.7 to 43.0%. The separation ...

  • Assessment of industrial by–product synergies from process engineering and sustainability principles

    Industrial synergy has long been one of the applications of industrial ecology; popularised in the 1980's. Industrial synergy increases the interaction between industries through the utilisation of wastes/by–products, thereby offering a closed–loop system. A target application for industrial synergy is Primary industry which generates a huge amount of waste. Historically however, most existing ...

  • New applications of beam–plasma systems for the materials production

    Beam–plasma systems (BPS) are known to be a great prospect for the surface modification of organic and inorganic materials. The present paper considers the plasma–assisted synthesis and deposition from the point of view of the hybrid materials production. Pilot setups in which the above processes occur in the electron–beam plasma (EBP) and combined plasma (CP) are described. The results of the ...

  • Europe’s objective: recycle more waste and send less to landfills

    Is waste a problem or a resource? Waste is both, depending on what we do with it. It is a problem because it can affect people’s health and the environment. For example, landfills are an important source of methane emissions, which is a powerful greenhouse gas contributing to climate change. Run off from landfills can contaminate ground waters and soil, which can then enter the food ...

  • Construction materials production. Application of the ABC-100 unit

    Expanded clay industry In the process of expanded clay production the argillous raw material homogenizes and mills in the drilling mud mixers and rollers. But these equipments not ensure qualitative desintegration. As result we obtain the expanded clay of low quality. Insufficiently desintegration and homogenizing of raw materials lead to the result when even 3% of carbonate ...

  • Recovery of volatile fatty acids (VFA) from complex waste effluents using membranes

    Waste effluents from anaerobic digesters of agricultural waste were treated with a range of membranes, including microfiltration and nanofiltration (NF), to concentrate volatile fatty acids (VFA). Microfiltration was applied successfully to produce sterile, particle-free solutions with a VFA concentration of 21.08 mM of acetic acid and 15.81 mM of butyric acid. These were further treated using a ...
