Municipal Waste Management in Saudi Arabia


The Kingdom of Saudi Arabia produces around 15 million tons of municipal solid waste (MSW) each year with average daily rate of 1.4 kg per person. The major ingredients of Saudi Arabian garbage 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

The sustainable integrated solid waste management (SWM) is still at the infancy level. There have been many studies in identifying the waste related environmental issues in KSA. The current SWM activities of KSA require a sustainable and integrated approach with implementation of waste segregation at source, waste recycling, WTE and value-added product (VAP) recovery.

Expanded Polystyrene (EPS): Boon or Bane


While no-one would deny its convenience, for waste managers, EPS is a challenge, for many of the same reasons that it is popular. It’s light and difficult to compact, so it fills up bins and collection vehicles quickly; and takes up a great deal of space if you try to bulk and haul it for recycling.

The economic and technical difficulty in recycling EPS, combined with the long-term impacts of its littering and disposal implies that environmentally minded people – and perhaps governments – should perhaps avoid it altogether.

The Promise of Solar Ponds


A solar pond is a three-dimensional, open-air pit, filled with water endowed with special properties. It receives solar energy through insulation, then the trapped heat is extracted from it from the water lying at the bottom of the pond.

Solar Ponds provide the simplest technique for transforming the sun’s energy into solar power, which can be extracted for different purposes. Solar Ponds are unique in their ability to gather and store energy simultaneously.

Conversion of Biogas into Biomethane


Each biogas-to-biomethane process has its own advantages and disadvantages, depending on the biogas origin, composition and geographical orientation of the plant. Amine scrubbers are a good choice when surplus heat is available for the regeneration of the washing liquid. With respect to cryogenic Liquefaction (CL) one may conclude that, this technology has a questionable track-record, is highly complex, hard to operate, and should therefore not be selected for small-medium scale applications.

Upgrading of raw biogas-to-biomethane (grid, CNG or LNG quality) provides additional utilization routes that have the extra advantage to be independent of existing infrastructure. Membrane based technology is the best way forward due to its ease of operation, robustness and the high quality of the end-products.

#InspireMENA – Inspiring Sustainable Development through Storytelling


#InspireMENA Initiative will work to raise awareness and magnify impact on sustainable development issues and projects throughout the MENA region. Each #InspireMENA story will be shared in both English and Arabic on both platforms. Professionals, volunteers and writers are invited through both networks to contribute to identifying stories, writing and translating articles.

More than half of that population in MENA is below 25 and is currently going through a lot in terms of political, economic, and social change. Despite all of this, young people across the region are innovating and making positive change in their communities. It is of utmost importance to support such impact with credible information, more visibility for success stories, and better communication tools.

Renewable Energy from Palm Oil Mill Effluent


Palm Oil Mill Effluent (commonly known as POME) is an attractive feedstock for biogas production and is abundantly available in all palm oil mills. Hence, it ensures continuous supply of substrates at no or low cost, positioning it as a great potential source for biomethane production. Most palm oil mills and refineries have their own treatment systems for POME, which is easily amenable to biodegradation due to its high organic content. The treatment system usually consists of anaerobic and aerobic ponds.

Due to the high fraction of organic materials, POME has a large energetic potential. By unlocking the energetic potential of these streams through conversion/ digesting and capture of biogas, palm oil mill owners have the opportunity to combine waste management with a profitable business model.

Climate Change in Kuwait


One of the main climate change impacts is sea level rise on coastal areas of all Arabian Gulf states. Kuwait is highly vulnerable to the impacts of sea level rise as it could lead to severe impacts on industrial and socio-economic development. Climate change-induced sea level rise may lead to flooding of low-lying urban infrastructure, inundation of coastal ecosystems and deterioration of groundwater quality….

Kuwait is both physically and biologically threatened by the climate change phenomenon. Over the next few decades, Kuwait could be potentially facing serious impacts of global warming in the form of floods, droughts, depletion of aquifers, inundation of coastal areas, frequent sandstorms, loss of biodiversity, significant damage to ecosystem, threat to agricultural production and outbreak of diseases.
