Current societal patterns of production and consumption drive a twin environmental crisis of resource scarcity and waste overload. Positioning waste and resource management in the context of ecosystem stewardship, this article relates increasing resource demand and waste production to the violation of planetary boundaries and human rights. We argue that a transition towards a circular economy (...

(2014) " Resource recovery from hazardous waste – the case of MSW incineration fly ashes " In: Proceedings " 4th International Conference Industrial and Hazardous Waste Management", 2.-5. SUMMARY: In the European Union almost 78 million tons of waste are annually combusted in Waste-to-Energy plants. Solid residues generated thereby contain altogether about 72,000 t/a of Zn, of which more than 5...

In humans and other mammals, the unexpected loss of a resource can lead to emotional conflict. Consummatory successive negative contrast (cSNC) is a laboratory model of reward devaluation meant to capture that conflict. In this paradigm, animals are exposed to a sharp reduction in the sucrose concentration of a solution after several days of access. This downshift in sucrose content leads to be...

Mr. Henderson brings up a subject that is going to become increasingly more important with the passage of time. As noted by the author and in an article by Marjorie Clarke in the January 1988 issue of Waste Age magazine, several states have enacted stringent air pollution control requirements for incinerators that, in some cases, are applicable to units as small as 20 tons per day (TPD). Many o...

This paper presents an excellent review of the theory of solid fuel combustion and NOx formation and control in the context of solid waste combustion. After pointing out that most research on NOx formation from solid fuels has been done on coal, the authors correctly point out that the while the basic principles of fuel and thermal NOx formation are well understood and permit NOx reductions in ...

A common approach to wastewater pretreatment in the food industry is the utilization of dissolved air flotation @AF) cells. DAF units are common for BOD, TSS, and FOG reduction when wastewater is discharged to a municipal wastewater treatment plant. A growing problem for all DAF systems is that of sludge disposal. In the o p t i o n of a DAF, contaminants are removed in the form of a concentrat...

This paper describes the applications of and specifi­ cations for trommels as used in various waste pro­ cessing and resource recovery operations. It provides system design engineers with general guidelines and rules-of-thumb useful in defining performance require­ ments, as well as creating design and construction spec­ ifications for trommels being used in areas such as raw MSW processing, cl...

Disruptive events can have severe economic consequences, and input-output models can be used to measure how direct impacts propagate to other economic sectors. Investing in infrastructure and industry sectors can lessen those direct impacts, but it is often difficult to determine the level of resources that should be allocated to prepare for a disruption and how best to allocate resources in re...
