  • Why is Energy-from-Waste slow to catch on in the U.S.?

    Nithin Coca reports in TriplePundit that Energy-from-Waste (EfW) is growing fast in Europe and parts of Asia. But it’s relatively stagnant here in the United States. In fact, the percentage of waste we burn for energy is actually slightly down in the past five years. What’s holding the U.S. back from this potentially sustainable solution? This stagnation is even more ...

  • How Do You Choose the Best Reverse Osmosis and Nanofiltration Membrane System for an Industrial Facility?

    As global demands for clean water increase, more and more industrial facilities are looking toward membrane filtration solutions, such as reverse osmosis (RO) and nanofiltration (NF), to help manage intake, process, and waste water treatment. Using membrane filtration can help your facility reuse wastewater and virtually eliminate discharge fees, and depending on the industry or required use, it ...

  • Why ‘custom-built’ is often cheaper than off the shelf

    We know that we’ve said it before, but even though we list what we call our ‘standard range’, by far and away most of the incinerators and cremators we manufacture are specially designed and manufactured to match the individual needs of each customer.  Since everyone’s requirements are different, virtually every unit we produce is ‘made to order’ and the ...

  • Confirming Natural Attenuation Processes at a Coastal Site - Case Study

    Past waste disposal practices at a California coastal site resulted in a groundwater plume containing CVOCs (mainly chlorinated ethenes [CEs] and 1,1-dichloroethane) migrating offshore towards a marine harbor. CVOCs are present in the sediment porewater adjacent to the shoreline, but concentrations decreased significantly between 2000 and 2015, and NA in the marine sediments was suspected. To ...

  • Crumbling Concrete Water Networks Linked to Common Water Treatment Additive

    Concrete distribution and sewer networks are being corroded at an alarming rate partly because of a commonly used additive in the domestic drinking water and wastewater treatment process according to published reports in the journal Science. In countries throughout the world from industrialized nations like Australia and the USA to developing nations like Colombia, Ghana and the Philippines, the ...

  • Do you know the two most important words required to understand oil spill booming?

    Much has been written (incorrectly) about how to deploy boom in order to protect, deflect or contain oil. We have long promoted using math and science when deploying spill countermeasures not only because it works, but because it’s faster, safer, more effective and it saves time, money and impact. What we’ll focus on in this article is the where of ...

  • Oil Recycling - Case Study

    The problem: Waste oil recycling contributes very much to climate protection through (CO2) energy saving. Compared to the production of base oil the re-refining of waste oil uses 34 % less resources. In the sixties the German government was subsidising the re-refining of waste oil. Because of that the use of waste oil as a fuel was neglected. The used oil re-refining is the ...

  • Aluminum recycling at Centro Rottami, Italy - Case Study

    Aluminum recycling is particularly important for the Italian economy, which has historically been lacking in raw materials – The showcase of Centro Rottami. Aluminum recycling is particularly important for the Italian economy, which has historically been lacking in raw materials. In fact, as much as 90% of the aluminum produced in the country comes from recycling, and is identical to ...

  • Reverse Osmosis and Nanofiltration Membrane Filtration Systems: Common Problems and How to Fix Them

    Reverse osmosis (RO) and nanofiltration (NF) are membrane filtration technologies that are designed to remove solute ions and molecules from a pretreated liquid stream. Well-designed RO/NF units are compact and demand relatively little maintenance, making them an attractive alternative to conventional treatment trains. Even despite the merits of today’s efficient RO/NF technologies, it pays ...

  • Scrubber Removes Grease and Particulates from Air Exhaust

    Operating Issue A food-industry leader in Alabama operates several pork-sausage cookers that exhaust over 4,000 ACFM of moisture and pork grease. The operator installed Electrostatic Precipitators (ESPs) to treat the exhaust but these systems performed poorly and generated high maintenance and operating costs. Additionally, these systems were antiquated and required significant capital ...

  • Waste Generation and Management

    Abstract Reported total waste generation within the EU and the European Free Trade Area increased by nearly 10% between 1990 and 1995, while economic growth was about 6.5% in constant prices. Half the waste comes from the manufacturing industry and construction and demolition activities, while municipal waste, mining waste and waste from other sources each contribute about one sixth of the ...


  • Designed for generations, water & wastes digest

    Nearly 25 years ago, the consulting engineering firm Banner & Associate, Inc. designed an efficient wastewater treatment facility for the city of Madison, S.D., that featured process control, flexibility and treatment efficiency while minimizing operating and maintenance costs. Key to the system was the aspirator aeration system that supplied reliable oxygenation and mixing to the oxidation ...

  • Biomedical Waste Generation in Puducherry Government General Hospital and Its Management Implications

    In India, not much attention has been paid to the management of biomedical waste (BMW). The present paper describes the collection and disposal of BMW in the Government General Hospital (GH) of Puducherry, India. The authors document (a) the lack of segregation between infectious and noninfectious BMW as well as a failure to implement the prescribed rules for proper management of BMW; (b) ...

  • Modelling waste generation by the telecom sector in Nigeria

    Since the introduction of digital mobile technology into Nigeria in 2001, there has been a phenomenal improvement in mobile subscription, service delivery and in the overall penetration of mobile telecommunication into rural areas in the country. For instance, the country's teledensity increased from less than 1% in 2001 to about 25% in 2006 — an increase of more than 3000%. The aim of this ...

  • Is it better to burn or bury waste for clean electricity generation?

    The use of municipal solid waste (MSW) to generate electricity through landfill-gas-to-energy (LFGTE) and waste-to-energy (WTE)projectsrepresentsroughly14%ofU.S.nonhydrorenewable electricity generation. Although various aspects of LFGTE and WTE have been analyzed in the literature, this paper is the first to present a comprehensive set of life-cycle emission factors per unit of electricity ...
