Recycling is the process in which used or abandoned materials from our everyday waste is converted into new products. Items that can be recycled include; glass, paper, plastics and various metals.  The process of recycling involves waste segregation after collection, processing the recyclable waste and finally manufacturing products from the waste thus processed. Why Do We Need Recycling? Manufacturing products involves obtaining raw materials from various sources. Raw materials may be from forests or mines. They are then transported to the place of manufacture usually by land or sea, which is an energy consuming process. Procurement of raw materials and … Continue reading →

A Holistic Approach to Tackling Food Waste Problem in Qatar

By | | ,
1 Comment

In a country that imports 90% of its food, discarded food accounts for about half of Qatar’s municipal garbage. These statistics point to the loss of millions of riyals each year, in the form of food wastage. The food in landfills rots to release greenhouse gases like methane which are responsible for the rise in temperatures which contributes to global warming. According to Project Drawdown, the global leader in quantifying climate change strategies, reducing food waste is the single greatest solution to reverse climate change, which could draw 87 gigatons of CO2 out of the atmosphere, way ahead of a global plant-based … Continue reading →

Textile Waste – The Next Big Challenge After Plastic Pollution

By | | , ,
Leave a comment

For decades, plastic pollution has dominated environmental discussions and policy agendas worldwide. Yet another environmental challenge is rapidly escalating and deserves equal attention: textile waste. The unprecedented expansion of the fashion industry, particularly the rise of fast fashion, has transformed the way clothes are designed, produced, consumed, and discarded. As a result, textile waste is growing at an alarming rate, creating serious environmental, economic, and social consequences that extend far beyond overflowing landfills. The global fashion industry has experienced extraordinary growth over the past two decades. Clothing production has more than doubled since 2000, while consumers now purchase approximately 60% … Continue reading →

Urban Integration of Waste-to-Energy Facilities: A Comparative Case Study and Framework for Sustainable Neighborhoods

By | | , ,
Leave a comment

The paper addresses the global and local shift towards the circular economy as a tool to achieve environmental sustainability and reduce climate impacts, given the global challenges of converting waste into energy. Through an analysis of global studies, the trend towards the circular economy and successful global standards, specifically the Danish model (Copenhill WTE plant) and Singapore (Tuas One WTE Plant), and how we utilize waste and achieve sustainability, this study discusses global strategies in the local context in Jordan, where it identifies current infrastructure challenges and proposes a sustainable local framework aimed at improving waste management and supporting the … Continue reading →

Waste-to-Energy Pathways: An Overview

By | | ,
14 Comments

Waste-to-energy is the use of modern combustion and biological technologies to recover energy from urban wastes. The conversion of waste material to energy can proceed along three major pathways – thermochemical, biochemical and physicochemical. Thermochemical conversion, characterized by higher temperature and conversion rates, is best suited for lower moisture feedstock and is generally less selective for products. On the other hand, biochemical technologies are more suitable for wet wastes which are rich in organic matter. 1. Thermochemical Conversion of Waste The three principal methods of thermochemical conversion of MSW are combustion (in excess air), gasification (in reduced air), and pyrolysis (in … 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 1.68 million marked by population density of 2,241 persons per km2, which is the highest in the entire GCC region. The country has the distinction of being the highest per capita waste generator worldwide which is estimated at around 906.7 kg of waste per person per year. Rising population, high waste generation growth rate, limited land availability and scarcity of waste disposal sites has made solid waste management a highly challenging task for policy makers, urban planners … Continue reading →

Analysis of a Composting Facility

The composting process is a complex interaction between organic 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 →

With high population growth rate, increase in industrial and commercial activities, high cost of imported energy fuels and higher GHGs emissions, supply of cheap and clean energy resources has become a challenge for the Jordanian Government. Consequently, the need for implementing renewable energy projects, especially solar, wind, biomass and energy-from-waste, has emerged as a national priority in recent years. Jordan has substantial biomass resources in the form of municipal solid wastes, sewage, industrial wastes and animal manure. Municipal solid wastes represent the best source of biomass in Jordan. Solid waste generation in the country is approximately 2 million tons per … Continue reading →

Like all other modern urban centers, the Middle East also faces challenges in environmental protection due to tremendous generation of plastic waste produced in different forms. The total solid waste generation in the Middle East region exceeds 155 million tons per annum, out of which around 15 percent is contributed by plastic wastes. The burgeoning population, growing consumption, and an increasing trend towards a “disposable” culture, is causing nightmares to municipal authorities across the region and beyond. Plastic consumption has grown at a tremendous rate over the past few decades as plastics now play an important role in all aspects … Continue reading →
