What’s That Smell?

What’s That Smell?

In many ways, material recovery facilities (MRFs) are harsher work environments than landfill working faces. During both operations, the protection of human health and the environment are primary concerns. While not exposed to the elements, the management of waste in a confined building has its own hazards. Enclosed facilities that

New Converts to Compost and Kilowatts

In 1915, a tragic farm accident reported in The Fruit Grower and Farmer was a mere footnote of local news. Patients from the State Hospital in Athens, OH, whose job was “to tramp down the silage comprised of corn stalks and leaves” were found asphyxiated in a tower silo. The report says

POWERING UP WASTE DISPOSAL

POWERING UP WASTE DISPOSAL

With the help of Volvo excavators, a waste-to-energy facility in Pennsylvania is undertaking significant site improvement efforts to lay the foundation for enhanced site safety and efficiency as well as establishing the infrastructure needed to manage increased waste capacity in the future.

On average, the United States generates 230 million tonnes

Energy management is an increasingly important topic across all business types, as buildings are one of their biggest energy consumers and producers. Buildings consume 40% of the energy and produce 21% of carbon dioxide emissions worldwide. Even more startling, one-third of the energy used in a typical facility is unnecessary,

The Costs and Benefits of Anaerobic Digesters

The Costs and Benefits of Anaerobic Digesters

Anaerobic digesters are a mature, proven technology. They take sludge, manure, and other organic waste materials and produce methane (natural gas) fuel. Nobody questions their technological capabilities. However, the question remains as to their economic benefits. In terms of dollars and cents, how much economic sense do anaerobic digesters make?

The common denominator among those employing energy management approaches is rising energy costs, points out Damian Smith, president/chief engineer for Total Energy Concepts. “It’s a hot topic as far as financials go, because it’s a direct expense that affects the bottom line,” he says. “When your costs go up on

Pittsburgh’s Commitment to Sustainability Driving Development of Innovative Solutions to Stormwater, Energy Use, and Shale Development Challenges

Pittsburgh’s commitment to a sustainable future is driving the development of innovative solutions and new, green technologies that address the challenges of reducing energy usage, addressing stormwater issues caused by aging and inadequate infrastructure, and reducing the environmental impacts of shale gas development.

These efforts and more are captured in detail

A Technology’s Transformation

A Technology’s Transformation

Fuel cell technology is elegant in its simplicity. An anode, a cathode, and an electrolyte allow positively charged hydrogen ions to move between the two sides of the cell, converting chemical energy into electricity. And the only bi-product is water.

Why, then, has this form of energy storage not been widely

We Want a Shrubbery

We Want a Shrubbery

We know trees are good for the urban environment, despite the occasional complaint that they shed too many leaves or eventually break up sidewalks. Now researchers in Europe are promoting what they say is an even better idea: hedges.

Prashant Kumar of Surrey University and others have just published research showing
