Outline Facts and figures about C&D waste in AB Solutions through City of Edmonton About our facilities and how we recycle Meeting Alberta s s Objectives in a new way 2
The C&D Waste Problem - some facts and figures 3
C&D Waste in Alberta 4
C&D Waste in Alberta 25% of the Total Amount of Municipal Waste Landfilled in Alberta 10% or less of total C&D generated is Diverted from Landfill Takes up upwards of 1 to 2.5 million cubic metres of landfill space per year 5

Facility Facts Project Budget $4.3 million Built over the 1987 tornado debris disposal cell Processing capacity up to 100,000 tonnes/year At least 50% diversion rate expected High operational flexibility able to segregate up to 9 different C&D material streams, in addition to unsorted lights residuals suitable for Refuse Derived Fuel (plastics, etc.) Cardboard, asphalt shingles, drywall, metals, untreated wood (e.g. dimensional lumber), treated wood (e.g. OSB, laminate) Concrete / asphalt Other potentially marketable materials (e.g. carpet underlays) 23

How We Recycle C&D 26
Downstream uses of recovered materials Untreated wood (e.g. dimensional lumber, trees and brush) are chipped and used in composting Drywall used as a compost amendment Asphalt shingles reused in asphalt production Concrete/asphalt crushed and used as roadway base Metals sold to metal recyclers Cardboard and paper marketed along with material from Blue Bag program Other wood materials become feedstock at the future Biofuels Facility Other materials plastics, carpet/underlay, glass, etc. exploring options. 27

Change of Course in Alberta 32
The Process That Almost Was. GoA conducted extensive consultation between 2006 and 2009 with with building contractors, engineers, architects, municipal government, landfill operators, recyclers and others. A MOU was signed in 2008 between AENV, the Alberta Construction Association (commercial builders) and the Canadian Home Builders Association Alberta (residential builders) to work together in developing a provincial C&D waste reduction program. Industry stakeholders showing support for a deposit refund based program to be administered by a Delegated Administrative Organization Alberta Environment.

A Non Legislated Opportunity The move towards legislation stalled, but in Edmonton we have the tools to achieve the same goals, including those stated by GoA Improve resource conservation and waste minimization Prevent pollution, and decrease GHG emissions Advance integrated resource recovery and waste management systems Taken from: Alberta Environment. 2007. Too Good to Waste. 34
Different Approach Similar Outcome Everyone Wins! 35
