Typically, 80% of potable water used  for municipal purposes returns to the environment as wastewater. Since  85% of Jeddah is not connected to sewerage pipelines, wastewater accumulates in underground cesspools […]

Biogas from Industrial Wastes

Biogas (or anaerobic digestion) technology is an attractive way to manage organic wastes in a sustainable manner. Organic waste includes a wide range of organic materials obtained from domestic, industrial and commercial operations. Most of the organic waste generated in developing countries is dumped into the landfills where it is not only responsible for large-scale greenhouse gas […]

Rationale for Recycling Lead-Acid Batteries

Lead-acid storage batteries (LABs) are widely used on a mass-scale in all parts of the world.  They act as power sources in a wide-range of equipment and appliances used by households, commerce and industry. LABs finds application in all modes of modern transport including cars, trucks, buses, boats, trains, rapid mass-transit systems, recreational vehicles etc. […]

Disposal of Palm Oil Mill Effluent

Palm Oil processing gives rise to highly polluting wastewater, known as Palm Oil Mill Effluent (POME), which is often discarded in disposal ponds, resulting in the leaching of contaminants that pollute the groundwater and soil, and in the release of methane gas into the atmosphere. Properties of POME POME is an oily wastewater generated by […]

Waste to Energy in Jordan

In terms of quantity per capita and constituents, the waste generated in […]

Waste as a Source of Energy

Wastes can be transformed into clean and efficient energy and fuel by a variety of technologies, ranging from conventional combustion process to state-of-the art plasma gasification technology. Besides recovery of substantial energy, these technologies can lead to a substantial reduction in the overall waste quantities requiring final disposal, which can be better managed for safe […]

Biogas from Leather Industry Wastes

The conventional leather tanning technology is highly polluting as it produces large amounts of organic, inorganic and other types of harmful pollutants. Wastes generated by the leather processing industries pose a major challenge to the environment. According to conservative estimates, about 600,000 tons per year of solid waste are generated worldwide by leather industry and […]
