Article
The interface between chemicals and waste legislation is a major problem for the envisaged circular economy. To re-use or recycle more waste, information on its composition is needed. The EU Waste Framework Directive obliges producers to document the presence of substances of very high concern in a new database (SCIP), which went online in January...
Article
Chemie spielt beim Recycling künftig eine größere Rolle. So soll „Scip“ – die neue Datenbank der EU – dafür sorgen, dass sehr gefährliche Schadstoffe nicht mit recycelt werden. Gute Idee! Doch drei Fallbeispiele zeigen, dass dies in der Praxis nicht einfach zu erreichen ist.
Article
The authors of this contribution comment on the ‘tricky relationships’ of chemicals, waste and product legislation. Considering the interfaces and intersections of these frameworks they formulate eminent policy recommendations aimed to ensure that ‘Circular Economies’ are capable of avoiding the ‘recycling’ of problematic chemical substances presen...

Background In the 7th Environment Action Programme, the European Commission targets two essential goals in the handling of substances and materials known by the buzzwords “non-toxic environment” and “circular economy”. There are numerous interfaces in product, waste and chemicals legislation in these two areas. This leads to conflicting objectives,...
Article
The „Circular Economy“ concept aims at maximizing re-use or recycling of products and materials from the technosphere. Hazardous compounds are among the most prominent obstacles towards this goal. Cadmium (Cd) belongs to the group of strictly regulated hazardous elements. In this paper, we collect the available knowledge about the fate of products...
Article
The presence of persistent pharmaceutical residues in environmental media and drinking water is a problem not only in the countries where most of the production of these substances takes place (India and China), but also in Europe. An effective strategy for reducing drug residues in the aquatic environment must include measures along the entire lif...
Article
Full-text available
What is understood by the circular economy concept is the re-use and recycling of used materials and waste. In many used products, hazardous compounds are found or might be present either because of the products’ present intended use or former applications that have been banned in the meantime. Clearly, recycling activities should not endanger man...
Article
Full-text available
The construction of waste incinerators often encounters resistance from the public. A minimum requirement for the acceptance of these installations is a modern air pollution control technology and a safe disposal of its residues. However, many products that enter the waste stream already contain heavy metals, persistent organic pollutants (POPs) an...
Article
Full-text available
The construction of waste-to-energy or waste incineration plants (as well as other large-scale plants) often meets with public opposition, not only in Europe but also in many emerging economies. In this article, we analyze the experiences made in Germany with a focus on the question of which are the minimum requirements for creating acceptance of t...
Article
Construction and demolition waste constitutes a large fraction of all the waste generated in Europe. Its specific impact can be considered rather low, but the large generated volume and embodied resource makes this waste stream an important focus of current European policies. The European Commission has proposed new targets and goals for this waste...

Since November 2014, BZL and E3 Environmental Consultants Ltd. (UK) produce the background report on Best Environmental Management Practice (BEMP) for the waste management sector to be used as a basis for the development of the referring Sectoral Reference Document (SRD) by the Joint Research Centre (JRC) of the European Commission in Seville.
Article
Full-text available
Background Global waste recycling streams are accompanied by pollutant emission and concentration of hazardous substances within material cycles. For the latter, the term “risk cycle” is introduced. E.g. the illegal or semi-legal export of hazardous wastes like electronic scrap in developing countries for recycling is associated with risks for man...
Chapter
RISKCYCLE is an artificial word which addresses the risks associated with the global recycling streams. As part of materials like waste paper, plastic, and electronics, pollutants and chemical additives are transported abroad, e.g., they are exported to emerging and developing countries. Here these pollutants/additives can cause risks for humans an...
Article
Waste management faces considerable problems as the increasing quantities of PVC products manufactured over recent decades come to the end of their useful lives. Despite large investments in PVC-recycling facilities over the past 5 years, less than half the fields of application of PVC are covered, and examples of true recycling remain rare. Logist...
Article
Occupational health considerations and pollution regulations dictate that waste treatment plant should operate as closed systems with high levels of automation, encapsulated biological stages and approved air pollution control systems. There are as yet no binding regulations for the proximity to residential areas. It is recommended that aerial micr...
Article
At two german garbage sorting facilities, germ concentrations in the air were analyzed at different working environments (waste reception, manual sorting). At plant A, maximum concentrations of total bacteria (14700 CFU/m3), gram-negative bacteria (7279 CFU/m3) and moulds (> 84806 CFU/m3) occurred in the air at the final manual sorting belts. Refer...
Article
At two composting facilities (plants D and E), contamination of the air with total bacteria and mould fungi, and in addition with gram-negative bacteria (only at plant D) was analyzed at different indoor sites and outdoor in the vicinity. Statistical validity of the determination of contents of microorganisms in air samples was guaranteed by the co...
Article
At three different composting facilities, co-composting of used panty diapers with an addition of 10% (weight) to the usual plant input was investigated for various hygienic and microbiological parameters. In nearly any case, a sufficient degree of germ reduction above 99.9% could be observed by determination of reduction rates of B. subtilis spore...
Article
Seven wood burning facilities were analyzed for their emissions of PCDD/F and other parameters while the input was varied. PCDD/F emission concentrations ranged from 0.004 to 9.820 ng I-TEQ/Nm3, with the majority of values > 0.1 ng I-TEQ/Nm3, even if the input was untreated wood. Highest concentrations occurred after addition of halogenated materia...
