How arborists view the issue of “waste wood” is changing. The number of landfills has been steadily shrinking, while tipping fees at the remaining facilities are rising continually. Disposing of waste wood was once merely a time and labor factor, but now carries with it considerably more expense. Many arborists have adjusted to the higher cost of handling waste wood by looking for value-added m...

For both the practitioner and student, the physical model is a manifestation of ideas. Modeling presents the opportunity to test, explore, speculate, compose, capture, iterate, and further the design process. Physical model making is central to architectural education and its design studios, a course type required each semester for undergraduate and graduate architecture, landscape architecture...

OBJECTIVES The objective of the present study was to evaluate and compare the efficiency of a filter based sampling method and a high volume sampling method for sampling airborne culturable fungi present in waste sorting facilities. MATERIAL AND METHODS Membrane filters method was compared with surface air system method. The selected sampling methods were modified and tested in 2 plastic wast...

As federal, state, and local regulations regarding waste disposal become more stringent, the need to address current disposal practices for waste aircraft engine lubricants and other fluid wastes has become a major issue. The purpose of this Air Force sponsored study [ I ] is to examine recycling as an alternative to current disposal methods and the steps required to implkment and monitor recyc...

The absence of compensation for third parties who are the victims of residual (that is, permitted) pollution can entail a violation of Rawls's second principle of justice. Environmental pollution, insofar as it is an uncharged cost, may lead also to an economically inefficient distribution of goods and services. Radioactivity and radiation dose are forms of pollution for which a control philoso...

Although thermal recovery of waste plastics is widely practiced in many European countries, reliable information on the amount of waste plastics in the feed of waste-to-energy plants is rare. In most cases the amount of plastics present in commingled waste, such as municipal solid waste, commercial, or industrial waste, is estimated based on a few waste sorting campaigns, which are of limited s...

Health care facilities produce significant waste (2200 kg/bed/year) creating 2% of greenhouse gas emissions and 1% total solid waste nationwide, with 20-70% of waste coming from operating rooms. We performed a waste audit of hip arthroscopy for femoroacetabular impingement (FAI) to understand its environmental impact and identify areas for greening practices. A waste audit of five hip arthrosco...

who share the benefits of the undesirable facility provide compensation to those who host the facility. The compensation could be in the form of direct payment to individuals in the community, or through investments to improve the community. Boerner and Lambert also detailed benefits that communities could reap by supporting the construction of polluting and waste facilities in their areas. Amo...
