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 →
Salman Zafar, Founder of EcoMENA, talks to Bhavani Prakash of Green Collar Asia about cleantech industry trends, and offers tips for professionals trying to enter renewable energy and waste management sectors. Green Collar Asia: How did you become so interested in renewable energy and waste management technologies? Salman Zafar: I am a chemical engineer by education. After completing my Master’s degree program in 2004, I got the opportunity to work as a Research Fellow on large-scale biogas power projects which initiated me into waste management/bioenergy sector. During the course of my fellowship, I was involved in the design, operation and troubleshooting of waste-to-energy plants and biomass energy … Continue reading →
Effective sustainable solid waste management is of great importance both for people’s health and for environmental protection. In Jordan, insufficient financial resources, growing population, rapid urbanization, inadequate management and lacking of technical skills represent a serious environmental challenge confronting local government. At the same time, energy remains Jordan’s top challenge for development. The energy needs to be produced in a sustainable way, preferably from renewable sources which have a minimum environmental impact. To face the future problems in waste management, as well as securing the demand of renewable energy, it is necessary to reuse the wasted resources in energy production. … Continue reading →
The population in the MENA countries has doubled during the last 30 years (from ca. 110m in 1980 to almost 220m in 2010). As per conservative estimates, the rate of urbanisation in the MENA countries will exceed 70% five years from today (average for all developing countries: 54%). The proceeding urbanisation and the population increase involve several problems and challenges for the national governments and also for the cement industry. The cement production of countries in the MENA region has almost tripled during the last 15 years up to approximately 500m tons Since the start of national revolts and demonstrations in … Continue reading →
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 →
The high rate of population growth, urbanization and economic expansion in the Middle East is not only accelerating consumption rates but also increasing the generation rate of all sorts of waste. Bahrain, Saudi Arabia, UAE, Qatar and Kuwait rank in the top-ten worldwide in terms of per capita solid waste generation. The gross urban waste generation quantity from Middle East countries has crossed 150 million tons per annum.The world’s dependence on Middle East energy resources has caused the region to have some of the largest carbon footprints per capita worldwide. The region is now gearing up to meet the challenge of … Continue reading →
Solid waste management is a big challenge for the government and local authorities in the Kingdom of Saudi Arabia. The country generates more than 15 million tons of municipal waste each year with vast majority diverted to landfills and dumpsites. Recycling, reuse and energy recovery is still at an early stage, although they are getting increased attention. Recycling rate ranges from 10-15%, mainly due to the existence of the informal sector which extracts recyclables from municipal waste stream. Waste management issues in the Kingdom can be resolved by creating a healthy general environment specifically targeting the waste sector which may … Continue reading →
The Kingdom of Bahrain is an archipelago of around 33 islands, the largest being the Bahrain Island. The population of Bahrain is around 1.2 million marked by population density of 900 persons per km2, which is the highest in the entire GCC region. The country has the distinction of being one of the highest per capita waste generators worldwide which is estimated at 1.67 – 1.80 kg per person per day. Infact, Bahrain produces largest amount of waste per person among GCC countries despite being the smallest nation in the region. Rising population, high waste generation growth rate, limited land … Continue reading →
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 →
Energy is the driving force for development in all countries of the world. The increasing clamor for energy and satisfying it with a combination of conventional and renewable resources is a big challenge. Accompanying energy problems in different parts of the world, another problem that is assuming critical proportions is that of urban waste accumulation. The quantity of waste produced all over the world amounted to more than 12 billion tons in 2006, which increased to 13 billion tons in 2011. The rapid increase in population coupled with changing lifestyle and consumption patterns is expected to result in an exponential … Continue reading →
MSW is a poor-quality fuel and its pre-processing is necessary to prepare fuel pellets to improve its consistency, storage and handling characteristics, combustion behaviour and calorific value. Technological improvements are taking place in the realms of advanced source separation, resource recovery and production/utilisation of recovered fuel in both existing and new plants for this purpose. There has been an increase in global interest in the preparation of Refuse Derived Fuel (or RDF) containing a blend of pre-processed MSW with coal suitable for combustion in pulverised coal and fluidised bed boilers. Pelletization of Urban Wastes Pelletization of municipal solid waste involves the … Continue reading →
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 →
