  • The risky business of resource recovery

    Waste management operations, like any transport business, have many risks attached to them and all operators should avoid the “Dodgy Brothers” ignore-the-risks to save costs approach! Any transport business with large vehicles working in tight city and site access areas is prone to accidents and near miss incidents. Add to that the hazards of working with lifting, loading and compacting systems. ...

  • On industrial symbiosis networks and their classification

    The objective of this paper is the classification and characterisation of regional/local industrial symbiosis networks/industrial ecosystems in order to create a framework for future research and to enhance the planning of these systems in practice. Because of inter-organisational cooperation, which is arranged based on spatial proximity between the actors, costs and emissions can be reduced in ...

  • How Innovation Flourishes within The Nexus?

    The awareness of the conspicuous synergies and antagonisms existing among the various socio-economic sectors that constitute the urban fabric, e.g. water and energy sectors, and the increasingly complex nature of environmental and resource scarcity problems have triggered the discussion on the water-energy-food nexus, referred to as ‘the Nexus’ in this article. The discussion has been ...

  • Towards zero waste, Italy

    In 1993 ThyssenKrupp was looking to improve its internal recycling of by-products. Harsco has a proven record of technology application in the field of resource recovery and production of valuable products form iron and steel making by-products. Harsco’s tailor-made solutions were a natural fit with assisting stainless steelmakers in the recycling materials that have traditionally been land ...

  • Salinity solutions: from ‘waste disposal’ to ‘resource recovery’

    Saline impaired water is a ubiquitous feature of the Australian landscape and the need for innovative technologies to deal with this issue is now a priority. The ‘waste disposal’ paradigm needs to change to ‘resource recovery’ especially with environmental and legislative requirements which limit the scope, cost efficiency and sustainability of conventional saline water ...

  • Reverse logistics and resource recovery: modelling car dismantling facilities

    Reverse logistics is addressed as new business issue promoted by the compulsory targets regulation enacted by the EU, to lower pollution and to reduce raw stuffs consumption. The paper gives a survey of the existing legal frame, and suggests the modelling and simulation path to assess the dismantling process. Such path permits the quantitative assessment of the recovery (reuse, recycling) ...

  • From Wastewater Treatment to Resource Recovery

    Recovering energy and valuable compounds from sewage adds value to the water-purification process Wastewater was once something to dispose of, but today it’s considered too valuable to waste. It is, in fact, rich in energy, nutrients, and other promising materials, not to mention the increasingly valuable resource of the water itself. As leaders in the sector realize the potential ...

  • Diagnosis and optimization of WWTPs using the PWM library: full-scale experiences

    Given the shift in perception of wastewater treatment plants as water resource recovery facilities, conventional mathematical models need to be updated. The resource recovery perspective should be applied to new processes, technologies and plant layouts. The number and level of models proposed to date give an overview of the complexity of the new plant configurations and provides a wide range ...

  • Managing the end-of-life of railway vehicles for resource recovery

    The railways transport has to be further implemented in the medium and long term to reduce traffic on the road and greenhouse gases emissions. The aim of the paper was the analysis of the end-of-life (EOL) of rolling stock and the evaluation of its management taking into account the sustainable use of resources and the reduction of waste. Considering that, at present, the EOL of this sector has ...

  • Project Fiberight Pilot Plant Demonstration Facility in Lawrenceville, VA

    Fiberight purchased the plant in 2010 for the sole purpose of integrating various pieces of equipment and operating conditions necessary to fully realize the Fiberight vision – maximizing resource recovery from Municipal Solid Waste (MSW). Since then, Fiberight has logged over 10,000 hours operating the plant. The nature of the demonstration facility has enabled a continuous optimization ...

  • Modelling and characterization of primary settlers in view of whole plant and resource recovery modelling

    Characterization and modelling of primary settlers have been neglected pretty much to date. However, whole plant and resource recovery modelling requires primary settler model development, as current models lack detail in describing the dynamics and the diversity of the removal process for different particulate fractions. This paper focuses on the improved modelling and experimental ...

  • A Highly Efficient Methanol Dosage Controller for Multi-stage WRRFs. Proceedings WEFTEC.15

    Abstract: A new model-based methanol dosage controller for multi-stage Water Resource Recovery Facilities (WRRF) is presented and compared with classic control approaches. The new controller uses self-tuning observer models to predict the concentration of methanol consuming organisms (methylotrophs) and subsequently the remaining methanol concentration in the denitrification zone effluent. This ...

  • Is human excreta a waste?

    Every day a huge amount of excreta is being produced by human society and it is also considered one of the most unwanted waste/refuse of the society because of its nuisance and diseases causing characteristics. However, it is also utilised as a fertiliser and soil conditioner in several countries such as India and China. Presently most common sanitation concept is centralised treatment of human ...

  • Valve innovation drives ion technology

    A NOVEL multiport distribution valve is at the heart of a new ion exchange system that reduces plant operating costs and capital expenditure by improving liquid–resin contact efficiency. The patented IONEX process can be used for resource recovery and purification in a wide range of industries, as well as water demineralization. Ion exchange systems are already used extensively for water ...

  • Plastics waste management and resource recovery in India

    Exponential growth in plastic production and consumption has evoked concerns for its effective management. Within a decade, India has witnessed a substantial growth of 890% and 340% in plastic production and per capita consumption, respectively. Plastic recycling industries have mushroomed autonomously and accounts for 47% of annual recycling. Further, unscientific collection, transportation, ...

  • Fluence’s MABR at the Codiga Resource Recovery Center

    A Membrane Aerated Biofilm Reactor (MABR) manufactured by Fluence Corporation (Fluence) was installed at Stanford’s Codiga Resource Recovery Center (CR2C) in January 2018. The system was tested with domestic wastewater diverted from Stanford’s sanitary sewer. Treatment performance was evaluated according to two benchmarks: California Title 22 standards for non-potable water reuse (T22) and a ...
