  • `Standards are desperately needed for plastic and pesticide contamination in soil´

    In addition to plastic in the oceans, plastic contamination in arable land throughout Europe and other parts of the world is a growing problem. No standards exist for these types of soil pollutants, nor for pesticide residues or their degradation products. For this reason, Professor Violette Geissen is calling for standards to be implemented. On 15 June, Geissen will deliver her inaugural address ...

  • Hazardous waste and not, Baioni-Dicatech system

    The identification, characterization and restoration of contaminated areas now represent a big environmental issue, both at European and national level. In the major industrialized countries the issue of contaminated land has come out in all its gravity in the late seventies when, against a widespread awakening of environmental consciousness, important pollutions events emerged. Consequently, in ...

  • Energy recovery from gas compressors

    With the development of natural gas recompression plants, linked to the opening of the global gas market, which means increased exchanges and transportation between production and consumption areas, the number of energy recovery projects on this type of installation is ...

  • Heat recovery

    A heat recuperator absorbs an important part of the calorific energy from gases generated in the combustion of a solid, liquid or gaseous fuel in the process of: melting, heating, toasting, drying, etc. of an specific product. The calorific energy absorbed is transmitted to another fluid, mostly combustion air for the process and fuel saving is so important that the recuperator is amortized in ...

  • Energy and phosphorus recovery from black water

    Source-separated black water (BW) (toilet water) containing 38% of the organic material and 68% of the phosphorus in the total household waste (water) stream including kitchen waste, is a potential source for energy and phosphorus recovery. The energy recovered, in the form of electricity and heat, is more than sufficient for anaerobic treatment, nitrogen removal and phosphorus recovery. The ...

  • Energy Recovery in Urban Wastewater Treatment on Global Scale

    ABSTRACT The lack of proper wastewater treatment results in production of CO2 and CH4 without the opportunity for carbon sequestration and energy recovery, with deleterious effects for global warming. Without extending wastewater treatment to all urban areas worldwide, CO2 and CH4 emissions associated with wastewater discharges could reach the equivalent of 3.13·105 tCO2·d-1 in 2025, with ...

  • Rethinking the green recovery through renewable energy expansion

    The world today is facing the worst economic and environmental crises in generations. Hence, we need policies that can stimulate recovery and at the same time reach the sustainability. United Nations Environment Programme (UNEP et al., 2008; UNEP, 2009a, 2009b, 2011) and many economists (e.g., Barbier, 2009a, 2009b, 2010; Edenhofer and Stern, 2009; Robins et al., 2009) advocate the need for a ...

  • Case study - Oxidizer energy recovery options

    Overview The mainstream media today is full of allusions to energy awareness and conservation. Just as visible these days are media references to astronomical dollar figures that can boggle the mind. This article does not seek to break out of that mold, but rather to conform to it – as Oxidizer Stack Heat Recovery offers a tremendous opportunity for both energy conservation and ...

  • Heat recovery from wastewater

    Heat recovery from gray water is particularly important in water-intensive industries such as pulp and paper plants, dairies and breweries. Rather than flushing used water down the drain, consider whether a heat exchanging system can help you put that energy to work in your process again. Most plant operators arc aware of the need to save money and reduce the environmental impact of their plant ...

  • Recovery, Recycling and Revenues

    Earlier this year, the UK’s Local Government Association (LGA) revealed that almost 615,000 tonnes of material is disposed of in England, even though it can be reused. It was calculated that by reusing this household waste, British tax payers could save up to £60 million. Most industries produce some form of waste whether it’s broken machinery, surplus food, or unused packaging. ...

  • Power Positive Resource Recovery

    Using laws of thermodynamic analysis to evaluate the energy and power characteristics of wastewater and beneficial uses of biogas offers greater insight into best business practices and what is achievable. Growing numbers of waste-water treatment plants (WWTP) are striving to produce more power onsite. In recent years, there’s even been a race among WWTP operators to see who can ...

  • Storm Debris Recovery & Processing

    Mobile wood grinding fleet, qualification as a preapproved cleanup contractor and reliable outlets for processed debris are keys to success. The weeklong winter storm that hit the south and East Coast last February was a record-setting event. The state of South Carolina lost 11 percent of its timber, with North Carolina and some East Coast states sustaining similar ...

  • Role of primary sedimentation on plant-wide energy recovery and carbon footprint

    The goal of this paper is to show the effect of primary sedimentation on the chemical oxygen demand (COD) and solids fractionation and consequently on the carbonaceous and energy footprints of wastewater treatment processes. Using a simple rational procedure for COD and solids fraction quantification, we quantify the effects of varying fractions on CO2 and CO2-equivalent mass flows, ...

  • Anaerobic co-digestion of surplus yeast and wastewater to increase energy recovery in breweries

    Surplus yeast is a residue produced during brewery process, which presents high contents of organic matter. Biogas production from yeast could significantly contribute to bioenergy production in breweries, via biogas generation. Co-digestion of surplus yeast and brewery wastewater in a single treatment step would simplify the technical and economical requirements for the transformation of both ...

  • An eco–sustainable model on energy recovery from municipal solid waste

    In the present day situation, the toxicity in municipal solid waste has increased to a very high level leading to various problems. The main purpose of the study is to improve the quality of mixed solid waste by adding locally available biomass. It was observed that the feedstock for refuse derived fuel and biomethanation contains 12% and 20% toxicity, respectively, as a result degrading the ...
