In the United States, the treatment, storage and disposal of hazardous waste is regulated under the Resource Conservation and Recovery Act (RCRA). Hazardous wastes are defined under RCRA in 40 CFR 261 where they are divided into two major categories: characteristic wastes and listed wastes.
Ignitability(D001)– Ignitable wastes can create fires under certain conditions, are spontaneously combustible, or have a flash point less than 60 °C (140 °F). Examples include waste oils and used solvents. For more details, see 40 CFR §261.21 . Test methods that may be used to determine ignitability include the Pensky-Martens Closed-Cup Method for Determining Ignitability (Method 1010A) (PDF) (1 pg, 19K) , the Setaflash Closed-Cup Method for Determining Ignitability (Method 1020B) (PDF) (1 pg, 17K) , and the Ignitability of Solids (Method 1030) (PDF) (13 pp, 116K).
Corrosivity(D002)– Corrosive wastes are acids or bases (pH less than or equal to 2, or greater than or equal to 12.5) that are capable of corroding metal containers, such as storage tanks, drums, and barrels. Battery acid is an example. For more details, see 40 CFR §261.22 . The test method that may be used to determine corrosivity is the Corrosivity Towards Steel (Method 1110A) (PDF) (6 pp, 37K).
Reactivity(D003)– Reactive wastes are unstable under “normal” conditions. They can cause explosions, toxic fumes, gases, or vapors when heated, compressed, or mixed with water. Examples include lithium-sulfur batteries and explosives. For more details, see 40 CFR §261.23 . There are currently no test methods available.
Toxicity(D004-43)– Toxic wastes are harmful or fatal when ingested or absorbed (e.g., containing mercury, lead, etc.). When toxic wastes are land disposed, contaminated liquid may leach from the waste and pollute ground water. Toxicity is defined through a laboratory procedure called the Toxicity Characteristic Leaching Procedure (TCLP) (Method 1311) (PDF) (35 pp, 288K). The TCLP helps identify wastes likely to leach concentrations of contaminants that may be harmful to human health or the environment. For more details, see 40 CFR §261.24 .
The F-list (non-specific source wastes). This list identifies wastes from common manufacturing and industrial processes, such as solvents that have been used in cleaning or degreasing operations. Because the processes producing these wastes can occur in different sectors of industry, the F-listed wastes are known as wastes from non-specific sources. Wastes included on the F-list can be found in the regulations at 40 CFR §261.31 .
The K-list (source-specific wastes). This list includes certain wastes from specific industries, such as petroleum refining or pesticide manufacturing. Certain sludges and wastewaters from treatment and production processes in these industries are examples of source-specific wastes. Wastes included on the K-list can be found in the regulations at 40 CFR §261.32 .
The P-list and the U-list (discarded commercial chemical products). These lists include specific commercial chemical products in an unused form. Some pesticides and some pharmaceutical products become hazardous waste when discarded. Wastes included on the P- and U-lists can be found in the regulations at 40 CFR §261.33 .
Now that a differentiation can be made between the two major categories of hazardous waste, one can go about a method of physically disposing of the waste.
Another type of waste that must be properly disposed of is non-hazardous waste. In Texas it is sub categorized into two classes.
Class 1 wastes are wastes which are regulated by the TCEQ and are potentially threatening to human health and the environment if not properly managed, because of the constituents and properties this class can include. Therefore, there are special handling requirements for Class 1 wastes. Examples are water contaminated with ethylene glycol, soils contaminated with petroleum hydrocarbons, liquids that are ignitable at levels above 150 degrees F, and semi-solids and solids when combined with water exhibits corrosive properties.
Class 2 wastes are often accepted at local landfills. Examples of wastes that fall under the Class II definition are depleted aerosol cans, non-surgical non-radioactive medical waste, and food waste and packaging that result from plant production, manufacturing or laboratory operations.
Now that the methods of disposal have been listed, depending on what and where the waste is located, trained and professional employees of Mantis Environmental will come to your location to resolve your waste issues. Mantis offers the following hazardous and non-hazardous waste services.
Mantis will assess your waste to make a determination on the identity and best treatment technology. In some cases an independent third party laboratory will be needed to confirm the identity of the waste stream. In the case of lab packs, the waste may be identified by general classification only.
In many situations, waste streams may be in partial containers. Mantis will segregate by compatibility and consolidate the waste as much as possible to reduce the number of waste streams. This also reduces the overall cost of the project while promoting waste minimization.
Waste will be packaged in DOT approved containers for transportation to the accepting disposal facility. The containers will be sealed, marked, labeled and otherwise prepared for transportation per all applicable federal, state and local regulations.
Lab packs are a specialty service wherein like chemicals are packaged by characteristics and compatibility. This service is utilized most often by education institutions and research type labs.
