Separating micropollutants from biowastes using anaerobic treatment facilities

Recycling of municipal organic wastes from separate collection systems becomes more and more important in the Federal Republic of Germany. Experiences gathered during the last few years indicate that the recovery potential of waste and biosolids strongly depends on quality of the produced composts or their pollutant load. This means that only really low polluted composts will be competitive in ...

Comparative evaluation of conventional and microwave hydrothermal carbonization of human biowaste for value recovery

This paper compares conventional and microwave hydrothermal carbonization (HTC) of human biowaste (HBW) at 160 °C, 180 °C and 200 °C as a potential technology to recover valuable carbonaceous solid fuel char and organic-rich liquor. Also discussed are the influence of HTC heating methods and temperature on HBW processing conversion into solid fuel char, i.e. yield and post-HTC management, ...

$Perspectives of composting and anaerobic digestion technologies for the treatment of organic fraction of municipal solid waste in Europe and Asia$

Perspectives of composting and anaerobic digestion technologies for the treatment of organic fraction of municipal solid waste in Europe and Asia

The development and implementation level of composting and anaerobic digestion technologies for municipal biowaste management in Europe and Asia are different in many aspects. The progress of these technologies generally depends on the lifestyle, waste generation rate, waste characteristics, awareness level, acceptability, market value and other economic factors. In Europe, regulatory directives ...

Integrated environmental biotechnology-oriented framework for solid waste management and control in Nigeria

Several environmental problems arising from man's activity have to be solved in a cost-effective and an environmentally friendly approach. In this paper, a framework for an integrated management and control of solid waste in the south-east zone of Nigeria is presented. The major activities include collection and transportation of solid waste to designated areas, separation of reusable components ...

Determination of sand content in digestate

The biological treatment of separate collected waste becomes more and more important. The composting is still the dominant method of treating this waste, but the anaerobic alternative, the anaerobic digestion, plays an increasing part. In Germany already 15% of the whole capacity of biological treatment plants for separate collected biowaste are of anaerobic digestion (Kern, 1998), because of its ...

Environmental evaluation of systems for the recovery of biogenic wastes

The recovery of waste materials is promoted by the German Waste Act 'Kreislaufwirtschafts- und Abfallgesetz'. It requires that among the recovery routes available for a specific waste category the priority has to be on those which are more environmentally compatible. As a restriction given by the law, only those recovery routes which are technically feasible and economically reasonable must be ...

Managing Compostable Bags At Anaerobic Digestion Plants

The highest and best use for treating residential food waste is through source separation, sending organics first to anaerobic digestion (to capture energy), followed by aerobic composting (to return nutrients to the soil). Sending food waste to anaerobic digestion (AD) facilities requires appropriate tools and planning for capturing high volumes of material with low contamination. Compostable ...

European Experiences With the Treatment and Digestion of Bio-Organic Waste

In the area of waste management environmental awareness has essentially increased and according technologies got more and more accepted in Europe within more than ten years now. During all the time BTA has gathered experiences by developing and realising flexible concepts for biowaste treatment plants of different design and capacities for the treatment of various waste streams: full scale plants ...

Biochemenergy: a project to turn an urban wastes treatment plant into biorefinery for the production of energy, chemicals and consumer's products with friendly environmental impact

Urban bio-wastes (UBW) contain soluble bio-organics (SBO) with excellent surfactant properties are proven or expected to perform as bio-based products for use in chemical and environmental technology, in agriculture and in animal husbandry as well as or better than commercial synthetic products. On these basis, UBW are proposed as renewable sources of a wide number of products with potential sale ...

The first supermarket in Portugal Case Study

Biowaste production is estimated to be 120 million tonnes per year in the EU alone, increasing by 10% each year. At least 40% of this is landfilled or incinerated with only 25% energy recovery, due to a lack of alternatives. When the Portuguese supermarket chain Continente looked for ways of reducing their operating costs and tackling their carbon footprint, SEaB Energy’s Flexibuster™ ...

Anaerobic Digestion Of Compostable Bags

Dry anaerobic digestion facility in Luxembourg successfully treats mixed yard and food waste collected in compostable plastic bags. Preprocessing, anaerobic digestion and composting operations are enclosed at the Syndicat Minett-Kompost facility. While the value of compostable plastic bags to increase participation in residential source separated organics (SSO) programs is well-recognized, much ...

Reasonable waste digestion plants

During the last years it became quite clear that in the area of utilisation of organic waste the anaerobic digestion has developed a leading position. This is not only based on its well known advantages:- abhigh rate degradation of organics- abcontained process- ablow emissions- abhigh yield of CO2-neutral produced biogas and high quality compost as its productsbut also on the fact that customers ...

Environmental efficiency of composting versus anaerobic digestion of separately collected, organic waste

Environmental policy in the Netherlands among others aims at closing material cycles and minimising the amount of waste requiring final disposal. In this policy the highest priority is given to the prevention of waste production followed by (in descending order of preference) reuse, incineration with energy recovery and sanitary landfilling. In the implementation of this solid waste policy also ...

Anaerobic procedures (fermentation)

Anaerobic technology is particularly well suited for the utilisation of organic industrial refuse with a high water content as well as for the organic part of bio-waste. A crucial factor for the increasing acceptance of anaerobic waste treatment is the fact that - in contrast to composting - the energy (digested gas) which is released during fermentation can be collected and used and enables ...
