Household waste recycling centres (HWRCs) evolved from civic amenity sites (CAS) introduced by the Civic Amenities Act 1967, and provide householders with an outlet for the disposal of a wide range of materials. Sites are now handling significant volumes of recyclables (66% of total household recyclables), and the transport impacts associated with increasing visitor numbers to HWRCs are of inte...

AIMS To evaluate different strategies for description of the sanitary quality of industrial-scale composting. METHODS AND RESULTS The investigation included microbiological analyses of waste at different stages during the process (spot test analysis), as well as physical and chemical parameters. The elimination of indicator organisms was also investigated by means of direct process evaluation...

This Report was supported by the Military Waste Cleanup Program under a grant from the Environmental Protection Agency, supporting research on the role of scientific and technical expertise, communication, and networking in providing better information to communities affected by hazardous waste cleanup activities at federal facilities.

Concerns and uncertainties persist about potential environmental and health effects associated with exposure to emissions from widely adopted waste management facilities: despite a limited amount of evidence having been found for some exposure-effect associations, most of the available studies were characterized by limitations related to poor exposure assessment, which could introduce biases an...

The recent proliferation of facility-siting conflicts underscores the need for new analytical techniques in which the external effects associated with noxious facilities are considered explicitly. In general, in prescriptive facility-location models it is assumed that having populations "closer", as characterized by transport or accessibility advantages, is better for desirable facilities, but,...

Fires involving materials being stored or processed in bulk can have severe impacts on the local communities and the environment. It is important that site managers at municipal recycling facilities (MRFs) are aware of all the potential fire hazards that exist on their sites in order for them to produce a comprehensive fire safety plan and an effective risk assessment. This article is intended ...

A local municipality has decided to build a sewage pit to receive residential sewage waste arriving by tank trucks. Daily accumulated waste are to be pumped to a nearby waste water treatment facility to be re-consumed for agricultural and construction projects. A discrete-event simulation model using Arena Software was constructed to assist in defining the capacity of the system in cubic meters...

The illegal dumping of waste has been a serious environmental concern of most countries in the world. This paper examines the relationship between the provision ofwaste treatment facilities and the frequency of illegal dumping. Our results show that a shortage of intermediate waste treatment facilities has played an important role in increasing the frequency of illegal dumping. 2010 Elsevier B....

Machine-learning algorithms have recently been applied to electrical power problems due to their potential to reduce waste and improve electrical grid reliability, but deployment of existing research is hampered by unrealistic assumptions. My thesis focuses on overcoming these assumptions. Autonomous agents have enormous potential to reduce electrical waste and improve reliability of the power ...
