Paper industry is considered as one of the world’s largest consumers of fossil fuels and biggest industrial polluter. The industry is criticized by environmental groups for being responsible for massive deforestation around the world. With the use of modern technology such as the printing press and the highly mechanised harvesting of wood, paper has become a cheap commodity. This has led to a high level of consumption and waste. Worldwide consumption of paper has risen by 400% in the past 40 years, with 35% of harvested trees being used for paper manufacture. Paper wastes constitute as much as one-fourth of the solid … Continue reading →

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. Need for 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 transporting causes … Continue reading →
The best way of dealing with waste, both economically and environmentally, is to avoid creating it in the first place. People and businesses that use resources wisely not only save money but also have much less impact on the environment. That is why waste prevention rightly occupies the top spot in the so-called “Waste Hierarchy” set out in EU and national waste legislation. Waste prevention is about the way in which the products and services we all rely on are designed, made, bought and sold, used, consumed and disposed of. For example: Making products that are more durable, repairable, re-usable … Continue reading →

The four Rs (reduce, reuse, repurpose, and recycle) of waste management have not yet entered the everyday discourse of Oman, but does this mean that they are not part of everyday life in Oman? We think the people of Oman can help us to answer this question. To get a first-hand understanding of the degree of waste management awareness in Oman, a pilot study was designed, a questionnaire was prepared, and in a series of interviews with individual Omanis we recorded their responses. Insights into the Survey The questionnaire covered household consumption habits, food waste and other household waste, and awareness of … Continue reading →
Solid waste management is considered to be one of the most severe environmental and civic problems in the Gaza Strip. Solid waste in the Gaza strip consists mainly of household waste, building debris, agricultural waste, industrial waste (mainly from worksites), medical wastes, and wastes from car workshops. Solid waste in the Gaza Strip is dumped in the same landfill without separation except for medical waste, which is dumped separately in the main Gaza landfill site. The solid waste generation rate varies between 0.35 to 1.0 kg/capita/day. Scale of the Problem Trash generation in the Gaza Strip varies between 830 to 894 tons/day … 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. Prevalent … Continue reading →

Rising population, high waste generation growth rate, limited land … Continue reading →
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 →
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 →
