Concept of Zero Wastes and
Role of Material Recovery Facilities
Salman ZafarFounder, EcoMENAwww.ecomena.org
7th Kuwait Waste Management Conference7 – 8 April 2015, Kuwait
Resolving Problem of Waste
Better organizationBetter educationBetter industrial design
Paradigm Shift
Recyclables used to be what we kept out of the garbage
Now garbage is what we have leftover after we reuse, recycle and compost
What is Zero Waste
New direction in waste management
Comprehensive socio-technical system
Addresses resource use from product design to disposal
Cradle-to-Cradle approach
In a Nutshell
"If it can't be reduced, reused, repaired, rebuilt, refurbished, refinished, resold, recycled or composted, then it should be restricted, redesigned or removed from production.“—Ecology Center, Berkeley
Defining Zero WastePragmatic and visionary approach
to guide people to emulate sustainable natural cycles.
Designing and managing products and processes to reduce the volume and toxicity of waste and materials.
Conservation and recovery of all resources, and not to burn or bury them.
Elimination of all discharges to land, water or air

Who is Planning for Zero WasteCommunities that:
◦Are running out of landfill capacity◦Can’t site new landfills or incinerators
◦Want to strive for sustainability◦Want to reduce greenhouse gas emissions
Why Zero Waste Strategy for Kuwait
Vast expansion in urban developmentsTremendous increase in waste
generation.Lifespan completion of
landfills/dumpsitesLack of engineered landfillsUncontrolled waste dumpingIncreasingly unsustainable lifestylesWorld’s largest per capita ecological
footprint
Conventional Waste Economy
Closing the Loop
Key Zero Waste Facilities
The MRF – Materials Recovery FacilityComposting Facility – to recycle
organicsRe-Use Facilities – e.g. like thrift storesC&D Facilities – Debris recyclingResidue DisposalWastewater/Biosolids Facility – solids
separation and anaerobic digestion facility
