Trends in Recycling of EPS Foam

Expanded polystyrene (EPS) foam, commonly known as styrofoam, the ubiquitous lightweight material used in packaging of electronic devices, food items and electric appliances, is popularly used because of its water and heat resistant properties. These properties likewise make it a preferred material for disposable food containers such as bowls, plates and coffee cups.  Due to its popularity, the global demand for EPS and its production is steadily increasing.  According to GBI Research, the global demand for both polystyrene and EPS increased to 14.9 million tons in 2010 from 13 million tons in 2000.1 This is expected to further swell to … Continue reading

Analysis of a Composting Facility

The composting process is a complex interaction between the waste and the microorganisms within the waste. The microorganisms that carry out this process fall into three groups: bacteria, fungi, and actinomycetes. Actinomycetes are a form of fungi-like bacteria that break down organic matter. The first stage of the biological activity is the consumption of easily available sugars by bacteria, which causes a fast rise in temperature. The second stage involves bacteria and actinomycetes that cause cellulose breakdown. The last stage is concerned with the breakdown of the tougher lignins by fungi. The composting process occurs when biodegradable waste is piled together … Continue reading

Making a Switch to Circular Economy

All forms of wealth and security, including climate stability, biodiversity, resource availability, soil fertility, air and water purity and health, are depleted by the systemic error of running a linear economy. Linear economics consumes the basis for future growth so what is now growing fastest is unproductive activity, inactivity and instabilities. The credit crunch marks the withdrawal of faith in growth-as-usual and any reliable revival of growth and prosperity requires a switch of vision. Circular Economics The future for growth is circular economics where more economic activity would mean a faster pace of change away from waste-making and towards looking … Continue reading

Recycling Attitudes in Saudi Arabia: A Survey

The waste management and recycling industry in Saudi Arabia is underestimated source of income. The continued increase in population and industrial development in the Kingdom has increased individual waste generation manifolds in the past few decades. The shortage of recycling industries in Saudi Arabia cost around SR 40 billion. The focus of Saudi recycling industry is plastic, papers and metals. If recycling industry targeted only plastic and paper and metals they can meet the need of the Saudi market efficiently. According to Arab League, recycling industry in Saudi Arabia can save over 500 million SR just from iron, paper and … Continue reading

Waste-to-Energy Outlook for the Middle East

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. High-income Middle Eastern countries like Saudi Arabia, UAE, Qatar, Bahrain and Kuwait are counted as world’s largest waste producers in terms of per capita waste generation which is more than 2kg per day in some countries. The urban waste generation from the region has now crossed 150 million tons per year which has forced policy-makers and urban planners to look for sustainable waste management solutions, including recycling and waste-to-energy. Let … Continue reading

Overview of Composting Methods

The composting process is a complex interaction between the waste and the microorganisms within the waste. The microorganisms that carry out this process fall into three groups: bacteria, fungi, and actinomycetes. Actinomycetes are a form of fungi-like bacteria that break down organic matter. The first stage of the biological activity is the consumption of easily available sugars by bacteria, which causes a fast rise in temperature. The second stage involves bacteria and actinomycetes that cause cellulose breakdown. The last stage is concerned with the breakdown of the tougher lignins by fungi. Types of Composting The methodology of composting can be categorized into three major segments—anaerobic … Continue reading

Industrial Symbiosis Prospects in Jordan

In a developing country, such as Jordan, with a relatively emerging economy and limited natural resources, the industrial sector expends more effort than developed countries and even more than developing countries that are rich in natural resources. In such a situation industries should look into finding solutions to sustain their existence, which is not confined to keeping their production lines running and making profit, but it goes beyond that, it goes to a whole way of thinking a way that integrates the surrounding environment and that confirms on the industrial sector responsibility toward the environment, the home of its raw material. Basically, this … Continue reading

Solid Waste Management Challenges in GCC

The challenges posed by solid waste to governments and communities are many and varied. In the Gulf Cooperation Council region, where most countries have considerably high per capita waste generation values, the scale of the challenge faced by civic authorities is even bigger. Fast-paced industrial growth, recent construction boom, increasing population, rapid urbanisation, and vastly improved lifestyle coupled with unsustainable consumption patterns have all contributed to the growing waste crisis in the GCC. Among the GCC nations, United Arab Emirates has the highest municipal solid waste generation per capita of 2.2 kg (which is among the highest worldwide) followed closely … Continue reading

An Interview with Paper Bag Boy of Abu Dhabi

Abdul Muqeet, also known as the Paper Bag Boy, has risen from being just another ordinary boy to an extraordinary environmentalist spearheading the fight against climate change in United Arab Emirates. Ten-year old Abdul Muqeet has demonstrated remarkable commitment to saving the environment and has won numerous awards including the prestigious Abu Dhabi Award. Here the Paper Bag Boy (PBB) talks to Salman Zafar, Founder of EcoMENA, about various aspects of waste management scenario in UAE: SZ: You are considered as the ‘recycling face’ of Abu Dhabi because of your wonderful achievements. Can you give an idea of the prevalent waste management … Continue reading

Attitudes towards Waste Management – The Case in Oman

Responses to the Oman waste management questionnaire were interesting, enlightening, and often unexpected. The Omani interviewees gave thoughtful answers and additional insights and opinions that stemmed from their sociocultural backgrounds as well as from their individual experiences. Often, statements and assertions from these respondents were found to be corroborated by evidence from other types of research, such as the study on the composition of refuse found in dumpsites in Muscat, or the feeding habits of camels cited earlier. Food waste On the topic of food waste, respondents generally had a strong belief that such waste was immoral. When asked about … Continue reading

Merits of Anaerobic Digestion of Wastes

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. 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

Introduction to Biorefinery

A biorefinery is a facility that integrates biomass conversion processes and equipment to produce fuels, power, and value-added chemicals from biomass. Biorefinery is analogous to today’s petroleum refinery, which produces multiple fuels and products from petroleum. By producing several products, a biorefinery takes advantage of the various components in biomass and their intermediates, therefore maximizing the value derived from the biomass feedstock. A biorefinery could, for example, produce one or several low-volume, but high-value, chemical products and a low-value, but high-volume liquid transportation fuel such as biodiesel or bioethanol. At the same time, it can generate electricity and process heat, … Continue reading
