The disposal and dumping of toxic waste is a matter of growing concern in developing countries, including South Africa. Frequently these countries do not possess access to gas chromatography-high resolution mass spectrometry (GC-HRMS) for the determination of persistent organic pollutants (POPs). This publication describes an alternative approach to the investigation of toxic waste using compre...

Abstract Management at a Municipal Solid Waste Landfill (MSWLF) is necessary to save the environment from pollution. MSWLF, which previously used sanitary landfill system, has changed an open dumping system. An system can cause decay environment. This study aims compare municipal solid waste disposal site management in two different regions. The research location Depok City and Klaten Regency. ...

The paper examines the interaction between host rock and a clay-based engineered barrier in the context of deep underground disposal of high-level radioactive waste. A large scale ‘‘in situ’’ heating test currently under way in the underground Grimsel Rock Laboratory (GRL; Switzerland) is adopted as a representative case for study. The main features of the behaviour of the rock/barrier system h...

In this paper comprehensive studies have been carried out for the design optimization of a waste heat recovery system for effectively utilizing the domestic air conditioner heat energy for Keywords—Air-conditioning system, Energy conversion system, Hot water production from waste heat, Waste heat recovery system.

Electronic waste (e-waste) is the fastest growing type of solid waste because of the continual improvement of electrical and electronic equipment. The e-waste recycling business is a large and rapidly consolidating business in all areas of the developed world (US Environmental Protection Agency 2011). The recovery of precious metals, such as copper, gold, silver, and palladium, is the incentive...

In this Era of globalization when GDP of most of the countries are spending on an average 8% of the economy on infrastructure and when we see around us about the term infrastructure mostly we see the huge contribution of concrete in it; in addition to this three important terms are named as “Quality, Quantity and Economy”. There is a deadly race among the nations of various parts of the globe t...

The safety of an underground waste disposal site depends to a large extent on the presence and migration of the water in the rock. Geoelectrics is the most suitable method particularly in underground mining conditions to explore and monitor the moist zones in many different rocks. Recent developments in hardware, inversion schemes and petrophysical interpretation of the resistivity enable relia...

Inhibition of the respiration microbial activity in the activated sludge caused by heavy metal concentrations (Cr, Cd, Cu and Ni) was studied by means of respirometric method using Strathtox respirometer (Strathkelvin Glasgow).The studied sludge samples were obtained from the two waste water treatment plants with different types of pollution (municipal waste water and domestic waste water). Key...
