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

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

Waste Management Hierarchy of 6Rs

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
