Landfill Airspace Preservation
Available airspace cited by Solid Waste Task Force as major business concern to the City’s Solid Waste Management Program.
The City doesn’t own a landfill and must negotiate pricing for precious airspace commodity.
Area growth and development consuming nearby land which will also drive future disposal costs.

Wood Waste Recycling – Fiscal Issues
COH must be a good steward of public resources (tax dollars). Wood waste material is easily recyclable. Sufficient local markets for material. Disposal Costs increase on average of approx.
$900K per year.
Proper Environmental Stewardship as a “Green City”. Carbon Credits to be gained. Potential Revenue for the sale of Carbon
Credits.
Greater Houston Area Density Projected to significantly increase in near future. Houston, Sugarland, Baytown population
expected to grow from 4.7M in year 2000 to between 8.4M – 11.1M by year 2040.*
Harris County Population expected to grow from 3.4M in year 2000 to between 5.8M – 6.6M by year 2040.*
* Texas State Data Center 2006 population projections.

Air Quality
Houston air quality is monitored very intensely by governmental units and private industry.
At least 141 air pollution monitors screening for up to 138 chemical compounds.
Several initiatives in process to improve Houston air quality.
Wood Waste Diversion contributes to improved air quality with landfill GHG reduction.
“Houston Smog”

Wood Waste Recycling Diversion The amount of material to be diverted,
approximately 90,000 Tons; or close to 660,000 cubic yards
If stacked on the playing field of Reliant Stadium, (54,000 sq. feet) would reach nearly 1000 feet high, the height of Chase Tower
SWMD - Wood Waste Briefing 14
Wood Waste Pilot Program
Approximately 47,000 homes in pilot area.
Estimated tons not landfilled 30% - 40% of normal service.
Estimated Cost Savings of $260,000 for pilot area.
Grinding Savings of $10 - $15 per ton donated by LETCO (pilot area only).
Council Districts Currently Affected: A, B, C, D, F, G, H
