Electronic waste Electronic waste‚ e-waste‚ e-scrap‚ or Waste Electrical and Electronic Equipment (WEEE) describes loosely discarded‚ surplus‚ obsolete‚ or broken electrical or electronic devices. Informal processing of electronic waste in developing countries causes serious health and pollution problems. Some electronic scrap components‚ such as CRTs‚ contain contaminants such as lead‚ cadmium‚ beryllium‚ mercury‚ and brominated flame retardants. Even in developed countries recycling and disposal of

When Philippine President Gloria Macapagal – Arroyo took office in January 2001‚ the first act she signed into law dealt with solid waste management systems have posed serious health risk particularly in densely populated areas. In Manila‚ for example‚ the closure of the largest disposal site in 2000 combined with inadequate capacity at other sites resulted in the disposal of tons of waste along city

Hazardous Waste Regulation RCRA There are two key regulations that govern hazardous waste sites in the United States. The first one is the RCRA or The Resource Conservation Recovery Act‚ which was passed by congress in November of 1976. The RCRA was developed to address the growing challenges the nation was up against from the growth of the volume of municipal and industrial waste. The RCRA has goals of; protecting human health and the environment from hazardous waste disposal‚ conserving

VIPAR ENGINEERING PYROLISIS PLANT INNOVATIVE DESIGN WITH LOW INSTALLATION COST AND HIGHER EFICIENCY Technology Pyrolysis involves heating waste tyres /plastic without oxygen to break them down to char or carbon black‚ oil‚ and gas. Plants operate within a temperature range of 250° - 500°C.At temperatures above approximately 150°C tires release increasing amounts of liquid oil products and gases. Above 400°C‚ depending on the process employed‚ the yield of oil and solid tire-derived char may

to produce output power. There are two types of engine; spark ignition and compression ignition engine. The diesel engine works on diesel oil‚ a non-volatile fuel. The self-ignition temperature is comparatively low. In this case fuel is injected directly into the combustion chamber at high pressure at the end of the compression stroke. Self-ignition occurs due to the high temperature of air because of the high compression. Spark plug and ignition are not necessary as in the case of spark engine.
