Waste from a burden to an asset in Saudi Arabia ? MEng. Melle B van der Meulen, Senior Consultant MHV Consultancy Ltd 2014
“Waste” is no waste any more International waste lists name more and more “recycled products” no longer ‘waste’, but international free tradable PRODUCTS. Including energy out of waste. Nearly daily former waste streams no longer objected as ‘waste’ according the international Green List and are free tradable. Paper, carton, metals, textiles etc. Steel scrap and non-ferro materials big example since 25 years Products are delivered to the international goods market, both regulated and non-regulated, depending of national structure. European waste consortia very effective in international expansion due to this strategy ‘from waste to commodities’
How from ‘Waste” Management to “Supplier of Products”
Waste doesn’t disappear Waste can only be converted and minimized, not disappear ! CONVERSIONCONVERSION Re-usable materials Energy carrier (gas) Energy (heat/electricity) Waste / Remains
“Recycling” is a “PRODUCTION process” with raw materials and products Conversion of waste into products or into energy, to be sold as ‘products’.
“Preferred pyramid” by international standards for waste management and legislation
Conditions for recycling A.Presence of waste (upstream market) with Sufficient quantities Required composition with enough recyclable materials Secured flow (guarantees on continuity) Secured flow by regulations (legislation) or by commercial purchase Commercial acceptable costs
B.Presence of market for products (downstream market) stabile quality of the products delivered secured market with multiple clients commercial market or created by regulations (national obligations to use recycled materials in the production of goods or in public contracts (for example. C&D waste products to be applied for 20% in public contracts by contractors ) Conditions for recycling
Recycling process visualisation Recycling ‘chain’. UPSTREAM Recycling processDOWNSTREAM NO secured UPSTREAM or NO secured DOWNSTREAM = NO recycling commercial feasible !
Specific problems of recycling in Saudi Arabia Scavenging is a social problem, eliminating 60-80% of the recyclables before processing in a MRF No internal market of any importance for recycled products, traders exporting and dominate the market Energy is too cheap (energy prices are leading for WtE) Landfilling is too cheap (many non-engineered landfills with low costs) Low public awareness about ‘recycling’ and ‘waste’ Low developed or non existing separate collection (low quality of recycled products by ‘dirty MSW’) Authorities consider waste management still as a ‘source of profit’ instead of ‘solving a burden’ ( no profitable investment based on BOT)
Cohesion with European legislation EU Waste Directive 2008/98 EC 1 : General obliged: 1 Specific: % recycling of MSW 70 % recycling and re-use of C&D waste
Gate fees or subsidizing products of recycling. Many PPP’s, semi-comm. No gate fees or low gate fees and no subsidized products. Few PPP’s, majority commercial 2003
Increase in recycling, decrease in landfill European Union. Overall oversight.
Construction and demolition waste in Europe Source 1 Do it your self market, households Source 2Professional market, construction Source 3Professional market, demolition Started with governmental contracts which obliged to re-use recycled materials. Private companies followed with woodchip production out of waste wood, plastic recycling, separation at the source (construction sites) and stimulated by lower waste tariffs of the waste management companies for separate collected C&D waste. Buildings are not ‘demolished’ anymore but ‘disassembled’ with crushing of stones and concrete at the site, sold as ‘aggregate replacing virgin materials’. Asphalt is 100% recycled.
C&D waste recycling in EU in 2009 Source: UBA 2008 and ETC/RWM 2009
Figures show a clear shift from landfill to recycling. Incidentally to WtoE. Figures show that gate fees or subsidizing recycled products work effective Most successful countries with PPP constructions instead of only commercial Legislation stimulates use of recycled materials (creating downstream market) Waste Awareness Program fully implemented (Education, information and stimulation by rewards as return systems for several waste flows like PET, glass, paper,electronic appliances, cars, motorbikes etcetera) Waste from a burden to an asset in European Union?
Waste from a burden to an asset in Saudi Arabia ? Conclusion: Yes, this is possible. There is a need for a drastic change, on a short term. The present pollution and spillage is horrifying and anti-Islamic. The changes to be made are big, small steps will not solve the problems but increase them External knowledge and experience need to be applied, including training of the Saudi experts Nation wide awareness required and religious efforts to support (Friday sermons by imams)
10 steps to establish a modern recycling environment in Saudi Arabia 1Consider ‘waste’ as a social and religious problem to be solved (Our Holy Qur'an forbids spillage and pollution) 2Education, information nationwide required about ‘waste’ and ‘waste prevention’ as a citizens duty 3Leave the BOT construction for recycling facilities and consider recycling as a joint effort by a PPP for a long term. Participation makes co-responsible for success. 4Some types of waste are always a burden, not an asset. Recognize that and subsidies the processing as a national interest (MSW, food waste, sewage sludge, hazardous waste, medical waste etcetera) 5Combat scavenging as ‘stealing from the community’ (what it actually is in a PPP construction)
6.Stimulate the application of recycled products and where applicable, oblige these (assuring the downstream market of the processes, public contracts) 7.Ban on export of recycled products which have an internal market in Saudi itself, licensing export. 8.Subsidize the processing of non-profitable waste flows by gate fees or by subsidizing the recycled products. 9.Forbid ‘fly-tipping’ of waste (C&D waste) because risks to be mixed with hazardous waste. Filling of construction areas to be done with recycled aggregates, controlled and licensed 10.Consider some ‘waste’ as a valuable fuel, competing with fossil fuels. Attractive as a by-fuel for power plants, cement industry and similar. ( As fossil fuels are subsidized, alternative fuels have to be as well)
Thank you for your attention and a clean and sustainable Saudi Arabia will benefit us all. With the help of Allah we will succeed to make Saudi Arabia a ‘green’ country, an example in the Islamic world.
