Waste Generation

Measuring waste generation tracks progress in waste reduction efforts, process efficiency improvements, and productivity.

Waste Generation

GRI:
EN22

Ecology’s operations include six major offices located within five main office buildings . Wastes generated by Ecology at these sites and at Ecology’s Manchester Laboratory are managed by staff and contractors. At the three leased offices (Central, Northwest, Richland) the landlord also has a significant role in waste management.

Small Quantity Generators of hazardous waste (less than 220 pounds per month or batch) are not required to report quantities of hazardous waste generated under federal and state laws and Ecology generally does not track the quantities of these small waste streams.

All of Ecology’s facilities are small quantity generators of hazardous waste. Hazardous wastes are recycled or disposed through local government Moderate Risk Waste (MRW) collection programs or by permitted contractors.

Ecology’s Manchester Laboratory (EPA ID# WAD988471892) generated 1867 pounds of lab packs in CY 2011 consisting of laboratory analytical wastes. These are used chemicals resulting from sample testing and designate as dangerous waste in Washington State.

In the reuse category, all obsolete electronic equipment (e.g. computers, phones, network equipment) is declared surplus and sent to the Washington Department of Enterprise Services (DES) and subsequently auctioned as used products or recyclable material. Ecology’s Lacey building (Headquarters and Southwest offices) shipped an estimated 3710 pounds of electronic equipment to DES as surplus products during FY 2011.

Ecology’s Lacey building (Headquarters and Southwest offices) generated waste streams in the quantities listed in the table below.

Qualitative Data (Northwest, Central, Eastern, Richland Nuclear Waste Program (NWP)

Ecology’s smaller regional offices do not measure waste streams generated. SWRO is an exception due to its location within the headquarters building. The following table notes which waste streams are generated at the regional offices and how they are managed.
