Because of legal regulations in Germany the biological treatment of organic residues is becoming more and more important. Following the regulations of the Waste Avoidance, Recycling and Disposal Act (KrW-/AbfG) and the TASi (Technical Data Sheet of Urban Wastes) biowaste has to be collected and treated separately. The waste management objective of the separate collection and biological treatment ...
This work has been carried out to check the ability of three biowastes, viz. corn cob ash (CCA), mango stone ash (MSA) and orange peel powder (OPP), to remove Ni(II) ions from aqueous solution. The surface environment of the adsorbents was characterized by Fourier transformation infrared spectroscopy and scanning electron microscopy (SEM) analysis which showed that these adsorbents contain ...
The decomposition stage and stabilization of organic matter in biowaste (mixture of yard waste and kitchen waste), originating from an open windrow process, were investigated using Fourier transform infrared (FT-IR) spectroscopy and pyrolysis-field ionization mass spectrometry (Py-FIMS). These investigations provided detailed information about chemical constituents and their behavior during the ...
Separate collection of organic waste may be considered as an integral part of contemporary waste management schemes. In this function it became widely accepted in the last ten years. It pursues the idea of a recycling economy according to the European hierarchy of waste - prevent, reduce, recycle - and is aimed at closing nutrient cycles. Nevertheless, separate collection at source essentially ...
THE past 15 years have seen significant investment and development of the biowaste collection and treatment industry in the United Kingdom (UK), which has gone from virtually zero to an industry worth over £160 million (264.6 million USD). Driving this investment have been a number of regulatory and fiscal measures such as the first set of Landfill Directive targets due in 2010. Since 1999, the ...
In recent years, utilisation of biowastes (especially biowaste composts) has gained greater significance in the Federal Republic of Germany. Whereas less than 1 million tonnes of biowaste was source separated and utilised in 1990, more than 6 million tonnes of biowaste are currently used as fertilisers after composting or digestion. Since composting of source separated biowaste has gained a ...
Source separate collection of biowaste has been implemented in many countries in Europe, especially in the German- speaking countries and the Benelux. By separating the biowaste fraction, a waste fraction called rest waste or grey waste is left over. This fraction is in most instances landfilled or incinerated. However, rest waste still contains a considerable amount of organics (up to 65%) which ...
According to German laws municipal residual refuse MRR (biowaste, paper and glass are collected in separate bins) must be nearly mineralized before it will be deposited in a landfill, since this material can still contain 20 - 50 % biogenous organic matter leading to gaseous and liquid emissions. Especially the high-organic sieve fraction of MRR below 40 - 60 mm and with a thermal energy content ...
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 ...
Co-digestion of organic wastes together with livestock manure has received growing interest in Germany during the last 5 years because some waste acts have been changed in order to achieve a better protection of the environment and to promote the utilisation of wastes for the formation of renewable energy and secondary products which can substitute mineral fertilisers and conventional soil ...
Scottish Island to be the first to utilise Anaerobic Digestion in waste treatment Comhairle nan Eilean Siar Stornoway, Isle of Lewis, Scotland “We were convinced by ENER-G’s ability to install a system that met with our requirements for a facility that is an innovative combination of waste treatments and includes the UK’s first dry Anaerobic Digestion facility” ...
The world´s first fully automated sorting plant for MSW Waste and recycling company Romerike Avfallsforedling IKS (RoAF) has installed 16 of TOMRA´s AUTOSORT optical sorters to separate green bio-waste bags and recyclable fractions from Municipal Solid Waste (MSW). This award-winning site is the first fully automated sorting plant for MSW worldwide, requiring no manual ...
