Recycling & Reuse

Solvent Recycling & Recovery

TIER offers a range of recycling methods for reclaiming chemical solvents—from distillation and fractionation, to thin film evaporation. We can effectively isolate each solvent component to ensure a high-quality, high-purity output, then analyze and monitor results to meet our internal standards, as well as government regulations and customer specifications. TIER also offers a Tolling program, whereby we clean your spent solvents to predetermined specifications and return them for reuse—helping to reduce costs and promote sustainable environmental stewardship.

Fuel Blending

Fuel blending reduces dependence on fossil fuels in the production of cement and offers your company an alternative to incineration for your organic hazardous waste streams. TIER has the expertise to evaluate your organic waste to determine its compatibility with current, state-of-the-art fuel blending processes and requirements. For qualifying organic liquids, sludge, and solids with BTUs greater than 10,000 per pound, we can arrange pick-up in bulk or drums, and transport your waste to our fuel blending facility. Our experienced technicians blend all incoming waste streams to the meet the most stringent specifications of our cement kiln partners. Fuel blending reduces your waste management costs and maintains regulatory compliance while protecting the environment.

Universal Waste

In an effort to promote recycling and ensure proper disposal, The EPA adopted the Universal Waste Rule (UWR) in 1995, which subjects certain hazardous materials to streamlined collection requirements. This rule applies to widely generated waste materials including batteries, light bulbs, computer electronics, and other items containing mercury. TIER can consolidate, package, document and haul your universal waste on a one-time basis or at predetermined intervals—saving time and money, and reducing your risk of contamination or non-compliance.

Oil & Petroleum Products

TIER can manage the collection, transportation and pretreatment of your used oil and petroleum products, which once treated, can ultimately be sold to refineries and energy recovery sites. Not only does this convert waste into a valuable resource, it also reduces your company’s environmental impact and costs. TIER performs extensive pretreatment sampling of all incoming used oil and petroleum waste streams at our onsite laboratory to ensure that oil products are not contaminated.

Semi-Precious and Precious Metals

Many industries utilize semi-precious and precious metals in their production, generating waste that carries these metals. TIER can arrange for the collection, transportation and recycling of these wastes through metal smelters where the metals can be reclaimed and recycled. In addition, your company likely has a range of computer electronics components such as motherboards, CPUs, RAM memory, and hard drives, that may contain precious metals. Let TIER evaluate your precious metal scrap to determine its value, and develop a plan that most effectively maximizes the return on your processing investment.


Waste Water Treatment

As an option for managing your aqueous waste materials, TIER provides treatment of organic and inorganic liquid waste in drum and bulk forms. We work with treatment facilities, including our own TSDF, to safely neutralize industrial and commercial wastewater through chemical oxidation, precipitation, neutralization, stabilization and oil/water separation. Ultimately, we can customize a cost-effective, compliant solution without disruption to your company’s operations.


Hazardous Waste Incineration

High temperature incineration is one of the most efficient and effective methods for waste reduction and disposal. Used to thermally treat and destroy a wide variety of hazardous waste, it can often achieve volume reductions that exceed 90%. The resulting ash can be further treated and finally hauled to secure land disposal sites, strictly adhering to all regulations and guidelines. TIER offers a range of incineration options including rotary kiln, fluidized bed, and direct incineration technologies. We can also evaluate your specific needs and then tailor a plan that best meets them.

Non-Hazardous Waste to Energy Incineration

Commonly known as trash to steam plants, because the primary fuel is household garbage, waste to energy is an environmentally sound process using the heat generated during incineration for the benefit of energy recovery—typically in the form of steam. This steam can then be used to drive turbogenerators, and ultimately, produce electricity. By diverting waste from the landfill to the incinerator, TIER contributes to the valuable process of creating renewable energy and promoting sustainable environmental stewardship.



For permanent disposal of hazardous waste materials, TIER uses a network of preferred third-party facilities, which we regularly audit to ensure they meet all Federal and State regulations, as well as internal guidelines for safe and efficient disposition of hazardous waste streams. In addition to selecting the most appropriate site for disposal of your materials, TIER will ensure that proper stabilization of all hazardous waste to immobilize leachable metals and/or organics, will be performed at the ultimate disposal facility. Microencapsulation and macroencapsulation are commonly employed treatment methods used to achieve stabilization of contaminated debris. Typical hazardous wastes include: heavy metal and/or organic laden wastes, specific and non-specific source wastes, and characteristic wastes.


Whether your liquid or sludge materials are transported in bulk or drums, we choose the end-use site that will most efficiently and safely handle your non-hazardous waste materials—and provide greater economies of scale than you could achieve independently. TIER only partners with state-of-the-art facilities with closely regulated methods to protect you from any future liability. Typical non-hazardous materials include: non-hazardous industrial sludges, liquids or solids, asbestos-containing materials, petroleum-contaminated materials, and more.
