Animal Waste Management in Africa: Perspectives

By | | , ,
7 Comments

Livestock and poultry production are among the main economic activities in rural as well as urban areas of African countries. The livestock sector, in particular sheep, goats and camels, plays an important role in the national economy of African countries. In addition, the region has witnessed very rapid growth in the poultry sector. The livestock industry and poultry industry, however, are contributing heavily to greenhouse gas emissions and waste crisis in Africa due to the absence of a sustainable animal waste management system. Most of the manure is collected in lagoons or left to decompose in the open which presents … Continue reading →

Biomass Energy in Middle East

By | | , ,
7 Comments

The major biomass producing countries in the Middle East are Egypt, Yemen, Iraq, Syria and Jordan. Traditionally, biomass energy has been widely used in rural areas for domestic energy purposes in the Middle East region, especially in Egypt, Yemen and Jordan. Since most of the region is arid or semi-arid, the biomass energy potential is mainly contributed by municipal solid wastes, agricultural residues and industrial wastes. According to conservative estimates, the potential of biomass energy in the MENA region is about 400TWh per year. Municipal solid wastes represent the best source of biomass in Middle East countries. Bahrain, Saudi Arabia, … Continue reading →

Biomass Energy in Jordan

Jordan has promising biomass energy potential in the form of municipal solid wastes, crop residues and organic industrial wastes.  Municipal solid wastes represent the best source of biomass in Jordan. In terms of quantity per capita and constituents, the waste generated in Jordan is comparable to most semi-industrialized nations. Agricultural biomass offers a low energy potential due to arid climate in most of the country. The major biomass energy resources in Jordan are: Municipal waste from big cities Organic wastes from slaughterhouse, vegetable market, hotels and restaurants. Organic waste from agro-industries Animal manure, mainly from cows and chickens. Sewage sludge … Continue reading →

The Benefits of Anaerobic Digestion of Organic Wastes

By | | , ,
3 Comments

Anaerobic digestion is a biological process which stabilizes organic waste in the absence of air and transforms it into energy-rich biogas and biofertilizer. It is a reliable technology for the treatment of wet, organic waste. Organic waste from various sources is biochemically degraded in highly controlled, oxygen-free conditions circumstances resulting in the production of biogas which can be used to produce both electricity and heat. Almost any organic material can be processed with anaerobic digestion. Anaerobic digestion is particularly suited to wet organic material and is commonly used for effluent and sewage treatment. This includes biodegradable waste materials such as … Continue reading →

Biomass Potential of Date Palm Wastes

Date palm is one of the principal agricultural products in the arid and semi-arid region of the world, especially Middle East and North Africa (MENA) region. There are more than 120 million date palm trees worldwide yielding several million tons of dates per year, apart from secondary products including palm midribs, leaves, stems, fronds and coir. The Arab world has more than 84 million date palm trees with the majority in Egypt, Iraq, Saudi Arabia, Iran, Algeria, Morocco, Tunisia and United Arab Emirates. Egypt is the world’s largest date producer with annual production of 1.47 million tons of dates in … Continue reading →

Renewable Energy in Palestine

High population growth, increasing living standards and rapid industrial growth has led to tremendous energy demand in the Palestinian Territories in recent years. The energy situation in Palestine is highly different compared to other countries in the Middle East due to non-availability of natural resource, financial crunch and unstable political condition. Palestine is heavily dependent on Israel for meeting its energy requirements. Almost all petroleum products are imported through Israeli companies.  Israel controls energy imports into Palestine and thus prevents open trade in electricity and petroleum products between Palestine and other countries. Current Scenario Energy is increasingly becoming unaffordable for … Continue reading →

Working of a Modern Biogas Plant

By | | ,
24 Comments

Biogas plants are decentralized energy system that can lead to self-sufficiency in heat and power requirements, and at the same time reduces environmental pollution. A biogas plant stabilizes organic waste through natural biological process in the absence of air and transforms waste into biogas and biofertilizer. Such facilities are well-suited to wet organic material and are commonly used for treating biodegradable waste materials such as waste paper, grass clippings, leftover food, sewage and animal waste. The components of a modern biogas plant includes manure collection, anaerobic digester, effluent treatment plant, gas storage, and CHP or electricity generating equipment. Working of … Continue reading →

Waste-to-Energy Outlook for Jordan

By | |
5 Comments

A “waste crisis” is looming in Jordan with more than 2 million tons of municipal waste and 18,000 tons of industrial wastes being generated each year at an annual growth rate of 3 percent. Alarmingly, less than 5 per cent of solid waste is currently recycled in Jordan. These statistics call for a national master plan in order to reduce, manage and control waste management in the country. The main points to be considered are decentralized waste management, recycling strategy and use of modern waste management technologies. Currently there is no specific legal framework or national strategy for solid waste … Continue reading →

Waste-to-Energy Potential in Saudi Arabia

Leave a comment

The Kingdom of Saudi Arabia has been grappling with the problem of solid waste in recent years. Around 15 million tons of municipal solid waste is generated in the country each year with per capita average of 1.4 kg per day. Depending on the population density and urban activities of that area, the major ingredients of Saudi Arabian MSW are food waste (40-51 %), paper (12-28 %), cardboard (7 %), plastics (5-17 %), glass (3-5 %), wood (2-8 %), textile (2-6 %), metals (2-8 %) etc. Due to high population growth rate, (3.4% per annum), rapid urbanization (1.5% per annum) … Continue reading →

Changes On Your Home For A More Sustainable Living

Traditional houses were not built with the environment in mind. Most houses require a lot of energy for heating during cold seasons and cooling during hot seasons. A big percentage of houses are not oriented according to the direction of sunlight and wind to achieve better lighting and cooling. As the population continues to increase exponentially, some cities have started to experience the power and water shortage. This problem has led to frequent power and water rationing, especially during dry seasons. It is important for homeowners to renovate their houses so that they can reduce water and electricity consumption. Improve … Continue reading →

Biomass Energy and its Promise

Biomass is the material derived from plants that use sunlight to grow which include plant and animal material such as wood from forests, material left over from agricultural and forestry processes, and organic industrial, human and animal wastes. Biomass comes from a variety of sources including wood from natural forests, agricultural residues, agro-industrial wastes, animal manure, organic industrial wastes, municipal solid wastes, sewage sludge etc. When biomass is left lying around on the ground it breaks down over a long period of time, releasing carbon dioxide and its store of energy slowly. By burning biomass its store of energy is released … Continue reading →

Food Wastes Disposal Methods

Food waste is one of the most prominent waste streams across Middle East, especially in GCC region.  The mushrooming of hotels, restaurants, fast-food joints and cafeterias in the Middle East region has resulted in the generation of huge quantities of food wastes. The proportion of food waste in municipal waste stream is gradually increasing and hence a proper food waste management strategy needs to be devised to ensure its eco-friendly and sustainable disposal in the Middle East.  Food waste is an untapped energy source that mostly ends up rotting in landfills, thereby releasing greenhouse gases into the atmosphere. Food waste includes organic … Continue reading →
