Solar energy generates revenue from closed landfills

Let’s face it – there are only so many revenue-generating uses for a closed landfill. Unless you generate enough landfill gas (LFG) to make power generation or other LFG use feasible, the closed landfill sits not generating any revenue for at least 30 years. That’s why siting a solar array on a closed landfill can…

Coal combustion residuals – what should you consider before accepting them?

Unless you live under a rock, you know about the new CCR Rule, a RCRA Subtitle D Non-Hazardous Waste Rule that covers coal combustion residuals (CCRs). These include fly ash, bottom ash, boiler slag, and flue gas desulfurization (FGD) waste. I thought it would be interesting to share my thoughts on how the rules are…

Biogas energy recovery at a California wastewater treatment plant – Lessons learned

I recently worked on a very interesting project in California to design a biogas energy recovery system for a wastewater treatment plant (WWTP). The system recovers nearly 100 percent of the methane produced from anaerobic digestion of wastewater sludge and conditions it for heat and power generation and transportation fuel. The design integrates a BioCNG™…

Going mobile – satellite CNG fueling outpost is a win-win for Louisiana solid waste district and waste hauler

I’ve spent the past few years in the brave new world of alternative vehicle fuel. I thought readers might be interested in a recent project I worked on where a solid waste district negotiated a contract with its waste collection contractor to purchase BioCNG fuel. The win-win agreement meant the contractor could purchase a new…

Proposed NSPS and EG rules – the good, the bad, the ugly for small landfills

CornerPost bloggers have previously reported on proposed revisions to Municipal Solid Waste Landfill New Source Performance Standards (NSPS) and Emission Guidelines (EG) changes we saw back in 2014. Now it’s my turn to share information on what was actually included in the proposed rules, which were officially published in the Federal Register on August 27,…

Reevaluating hydrogen sulfide control equipment helps landfill owners realize substantial long term cost savings

Not long ago I was involved in a project at a landfill in New Jersey where a client was looking for ways to reduce the cost of treating landfill gas (LFG). The team conducted an evaluation of the changing parameters associated with the LFG and was able to generate substantial cost savings. I thought readers…

What’s trending in landfill gas utilization?

In November 2014, I had the honor of sharing the podium with 140 of the country’s leading experts on LFG and leachate at the Environmental Research & Education Foundation (EREF) summit, called Leachate & Gas Management – Regulatory & Operational Perspectives. It was easily the best technical exchange combining LFG and leachate information I have…

Tips on obtaining clean air permits for anaerobic digestion facilities

I’ve recently been deeply involved in permitting efforts for several dry anaerobic digestion (AD) facilities for Zero Waste Energy, LLC (ZWE). I would say that after preparing four permits in California (and successfully obtaining all four) and going after one more permit in Alabama, I have gotten a real window into what regulators are looking…

Safety tips for working with high-pressure gas systems

In the past few years I have been working with many more high-pressure gas systems, rather than the low-pressure systems typically found in the landfill and biogas industries. High pressure systems present different and additional hazards, so I thought I’d offer information on these hazards, and a few tips on how to deal with these…

Keeping up with changes to Renewable Fuel Standard program

The “snowpocalypse” that greeted Landfill Methane Opportunities Program (LMOP) attendees did not deter (most) attendees from the annual USEPA-sponsored event in Baltimore. About 750 professionals registered for the event; the extreme cold snow prevented about 150 from making the conference. Those who slogged through the snow were treated to a host of excellent presentations. One…
