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 →
Despite the spiritual perfection of the rites of the Hajj pilgrimage, there are some deep issues with its practical implementation. In a journey where one is meant to recalibrate one’s consciousness of the one true Creator, it seems paradoxical that such an excursion should lead to environmental harm (or destruction). Why is it then that I walk the street of the Haram (sacred land) and find them littered with boxes of chicken and rice, strewn on the curb in front of beggars who offer to pray for you in exchange of spare change? A Deluge of Waste In 7:31, the … Continue reading →
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 →
Plastic consumption has grown at a tremendous rate over the past two decades as plastics now play an important role in all aspects of modern lifestyle. Collection and disposal of plastic waste has emerged as an important environmental challenge and its recycling is facing roadblocks due to their non-degradable nature. There are four basic ways in which communities can offer plastic recycling collection services for plastic bottles and containers – curbside, drop-off, buy-back or deposit/refund programs. Curbside Recycling The first, and most widely accessible, collection method is curbside collection of recyclables. Curbside (or kerbside) collection is considered a low-risk stategy to reduce waste volunes and … Continue reading →
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 →
Plastics are an inseparable part of modern society. However, their safe disposal is a big and highly challenging issue. A typical UAE resident uses 450 plastic water bottles on an average in a single year1. With the equivalent of 43 gallons on an average per person in 2011, the United Arab Emirates had the fourth-highest level of bottled water consumption in the world. A whopping 11 billion plastic bags are used annually, according to statistics from UAE’s Ministry of Environment and Water. This goes on to add up to an annual overall waste of 912.5 kilogram per capita2, 3, and 4. These … Continue reading →
During the last decade, the movement towards biobased products has increased dramatically as a result of increasing environment awareness and high increase in fossil fuel prices. Polylactic Acid (PLA) is an eco-friendly polymer derived from lactic acid which can be produced by fermentation of renewable resources. It is a new type of biocompatible material produced from utilizing lactic acid as monomer. Since lactic acid is a non-toxic component, which exists in human metabolism, PLA is safe polyester for human-related applications. In comparison to traditional plastics, PLA has great potential in the plastic market. Petroleum-based plastic takes hundreds of year to biologically … Continue reading →
Disposal of plastic waste has emerged as an important environmental challenge in the Middle East where plastics make up as much as one-tenth of the solid waste stream. In affluent GCC nations, plastic waste composition in municipal solid waste is around 12 – 16 percent. Plastic waste in the region is continuously increasing due to increasing use of plastics in daily life. The Middle East is responsible for about 8 percent of the global plastic production. Plastic waste is a source of greenhouse gas emissions and ecological damage. Majority of the items found on beaches across the region contain … Continue reading →
