Landfill & Biogas


Let us help you destroy waste gas including methane and NMOC’s, reduce emissions (up to 98% destruction efficiencies), and optimize the production of valuable renewable energy.

Landfill And Biogas Solutions.

Biogas Conditioning

JZHC offers comprehensive biogas conditioning systems including expert landfill gas compressor capabilities for both the dehydration of and sulfur removal of landfill gas. If you need to use landfill gas as fuel in a gas-to-energy system, we can help.

Our systems are capable of handling up to 10,000 scfm and include a dual-pump skid with a 1,600-gallon, carbon-steel storage tank. Each system is fully automated through a master control panel for ease-of-use.

Leachate Evaporators

JZHC leachate evaporators drastically reduce operation man-hours, simplify maintenance, and streamline installation. Designed to work continuously without a dedicated operator, the system also features extended cleaning intervals and continuous, hands-free operation with automatic filling of the leachate and draining of the solids. Performance is never sacrificed, however, as the system effectively reduces leachate volume by as much as 98%.

Blower Skid Packages

JZHC blower skid packages help you operate cleaner and more economically, with minimized installation costs and start-up time. Our blower systems maximize waste gas collection by pulling waste gas from the landfill through a series of wells, then safely transporting it to the Zink biogas flare, a gas facility or other end-use location. Our pre-packaged blower skids offer skid capacities up to 12,000 SCFM for multiple flare systems and come pre-piped, pre-wired and pre-tested.

ZULE® Ultra Low Emissions Flares

The ZULE (Zink Ultra Low Emissions) Biogas Flare achieves a destruction efficiency rate greater than 99.5%—meeting the most stringent NOx, CO and destruction efficiency requirements. No other solution has more units in operation or a longer history of proven performance. ZULE offers the lowest achievable NOx in the industry, tested as low as 3–4 ppm, and near-zero CO emissions for temperatures as low as 1200°F. Using exclusive, patented JZHC technology, ZULE delivers a 60% NOx reduction and a 70% CO reduction over traditional biogas flares.

  • 0.025 lb / MMBtu NOx guaranteed
  • 0.06 lb / MMBtu CO guaranteed

ZTOF® Enclosed Flares

ZTOF enclosed flares completely conceal the combustion of waste gas while delivering high destruction efficiencies, smokeless operation, and eliminating radiation. You can acheive capacities up to 6000 SCFM with a single flare and 10:1 or greater turndown without any external or internal adjustments.

  • Suitable for any biogas application including landfill, carbon credit projects and industrial or agriculture digester gas
  • Available for specialized designs including low BTU gas streams, purge air gas from siloxane removal systems, coal-mine gas, and more

ZEF™ Elevated Flare System

This system processes a wide range of landfill waste gas compositions and flow rates, and is suitable for any biogas application, including landfill, carbon credit projects, and industrial or agriculture digester gas. The flare’s candlestick design is a cost-effective way to eliminate odorous methane during landfill decomposition.

ZEF meets EPA 40 CFR 60. 18 criteria for open flare emissions and design standards and provides 10:1 or greater turndown without any external or internal adjustments.

ZBRID Hybrid Thermal Oxidizer

ZBRID is a field-proven design that achieves a 98% or greater destruction efficiency. This hybrid technology oxidizes low BTU off-gasses (typically less than 15% CH4) from CO2 stripping processes and landfill perimeter wells, providing a cost-effective alternative to traditional thermal oxidizers for destroying low methane waste gas streams.
