1 Mecklenburg County Solid Waste Characterization Study Fall 2015 Nicholas Crawford Senior Environmental Specialist 2015 Recycling Operations Supervisor 2016 Study and Report Completed by GBB Solid Waste Management Consultants

2 Mecklenburg County, NC Over 1 Million People City of Charlotte and Towns of Davidson, Cornelius, Huntersville, Mint Hill, Matthews, Pineville 524 square miles 262k Single Family Households (193k City) 156k Multi-Family Households (133k City) Single Family Households in Towns 16k to 1600.

3 The Problem Residential Waste Stream Data Every Other Week Recycling Institutional Waste Gov t Buildings, School, Jails Multi-Family Communities Residential Drop Centers Unincorporated County Areas Assess Waste Diversion Programs

4 Sample Design Two Weeks of City of Charlotte Routes - Municipal Curbside Cart Collection Recycle Week / Non Recycle Week (Orange Week / Green Week) Six Towns Contracted Curbside Collection Four different contract vendors Multi Family Community City of Charlotte Contracts for about 90% of service Compactor or Cart depending on size and logistical factors Unincorporated County? County Full Service Drop-Off Center

5 Sample Design Compactors County Jails Charlotte Mecklenburg Government Center Commingled route with 8 yard box Charlotte Mecklenburg Schools County buildings Central Piedmont Community College

6 Cooperation & Coordination 11 Municipal Partnerships 7 Different Haulers City of Charlotte Solid Waste Services Republic Residential and Commercial Advanced Disposal RCS Signature Waste Waste Management
