Working of a Modern Biogas Plant

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 (or anaerobic digestion) plant includes manure collection, anaerobic digester, effluent treatment plant, gas storage, and CHP or electricity generating equipment.    … Continue reading

Waste-to-Energy Outlook for Jordan

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

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

How Water Treatment Help Us Achieve Environmental Sustainability

Water scarcity is one of the largest threats facing humanity today due to constant water shortages being experienced all over the world. Only a small percentage of the world’s water (about 3%) is fit for human consumption with two percent of this amount present in glaciers and ice caps. The United Nations has given water due prominence by making it one of its millennium development goals. Such is the importance of water that governments have started developing new technologies and projects to cushion its effects on the world population. These initiatives include desalination, rainwater harvesting, wastewater treatment and water location … 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

Organic Industrial Wastes in the Middle East

Organic industrial waste includes a wide range of organic materials obtained from industrial and commercial operation. Industries in Middle East countries produces a large number of organic residues and by-products whose disposal is a major problem for stake-holders. In recent decades, the fast-growing food and beverage processing industry has remarkably increased in importance in major countries of the Middle East. Since the early 1990s, the increased agricultural output stimulated an increase in fruit and vegetable canning as well as juice, beverage, and oil processing in countries like Egypt, Syria, Lebanon and Saudi Arabia. There are many technologically-advanced dairy products, bakery … Continue reading

Zero-Waste Kitchens and Low-Energy Cooking

Food is the single largest source of waste. Worldwide, we throw away about a third of our food. More food ends up in landfills than plastic or paper. The enormous amount of wasted food depends on our cooking and eating habits.  Generally, it is easy to be sitting at home, in front of your television, consuming whatever you want then throwing every‑thing in the trash. But have we ever thought, where does the garbage go? Zero-Waste Kitchens Given that most of the domestic waste originates in the kitchen, a green home should definitely include a zero-waste kitchen. Zero waste kitchens is … Continue reading

Biogas Potential in the Middle East

Anaerobic digestion is the natural biological process which stabilizes organic waste in the absence of air and transforms it into biofertilizer and biogas. 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.  Anaerobic digestion is particularly suited to wet organic material and is commonly used for treating animal manure, organic fraction of MSW, sewage and industrial effluents.  Anaerobic digestion is a unique treatment solution for organic wastes … Continue reading

Biofuels in Jordan: Perspectives

Jordan has good biofuels production potential in the form of crop residues, agro-industrial wastes and urban wastes. Biomass energy sector in Jordan is slowly, but steadily, developing. As per a recent World Bank report, the country is currently generating 3.5MW of power from biomass resources which represent 0.1% of the total energy demand in the country. However there is no available data on the amount of biofuels produced in Jordan. Jordan produces significant amount of biofuel feedstock in the form of lignocellulosic biomass, used cooking oil, animal tallow, agro-industrial wastes, industrial effluents etc.  In Jordan, transportation sector alone is responsible of 51% of final … Continue reading

Wastes as Energy Resource

The tremendous increase in the quantum and diversity of waste materials generated by human activities has focused the spotlight on waste management options. Waste generation rates are affected by standards of living, degree of industrialization and population density. Generally, the greater the economic prosperity and the higher percentage of urban population, the greater the amount of waste produced. A good example are the oil-rich GCC nations who are counted among the world's most prolific per capita waste generators. Reduction in the volume and mass of wastes is a crucial issue due to limited availability of final disposal sites in the … Continue reading
