Glass and bottles are a large component of waste due to their weight and density consisting of bottles, broken glassware, light bulbs and other items. The glass bottle use is not much declining due to rising consumers, high consumption and introduction of a variety of soft drinks and juices. Glass recycling is at a minimum in many countries due to lack of segregation, awareness and economic reasons. Management of glass bottles is a major challenge as it takes millions of years to degrade glass naturally. Glass bottles and jars are 100% recyclable and can be recycled endlessly without any loss … Continue reading →

The concept of waste recycling has been getting increasing attention in Saudi Arabia in recent years. The country produces around 15 million tons of municipal solid waste each year with an average daily rate of 1.4 kg per person. This rate is projected to double (30 million tons per year) by 2033 with current annual population growth rate of 3.4%. The major ingredients of Saudi Arabian municipal solid waste 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. depending on the urban activities and population density of studied region.

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 their … Continue reading →

A Holistic Approach to Tackling Food Waste Problem in Qatar

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 →

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 →

Waste-to-Energy Pathways

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 →
