Hertz and Liberty Tire Recycling have launched what they call the first nationwide tire recycling program in the U.S. car rental industry.

Hertz says the program also makes it the first to commit to zero landfill waste for tires.

Under the program, Hertz will use Liberty’s nationwide service to collect its used tires, more than 160,000 annually, which will be transformed into a range of products for playgrounds, public parks, highways and other applications.

The companies say that volume of tires could produce enough rubber mulch for 366 playgrounds, or could pave 20 miles of a four-lane highway with rubber-modified asphalt, which reduces urban heat island effects when compared to conventional asphalt. Rubberized asphalt also rides quieter, lasts longer, and uses significantly less paving material than traditional asphalt, Liberty says.

Liberty Tire Recycling describes itself as the largest tire recycling company in North America. Its recycled rubber feedstock produces a range of products including mat flooring and crumb rubber for composite railroad crossties.

Hertz’s sustainability efforts include offering a collection of alternative fuel and high-MPG vehicles, from electric vehicles to clean diesel, in its Green Traveler Collection lineup. The company’s car sharing service, Hertz On Demand, offers EV and hybrid options including the Nissan LEAF, Chevy Volt and Mitsubishi iMiev. Recently, Hertz also expanded its electric car rental program through a pilot initiative with Plugless Power, which allows EVs to charge without being plugged into an outlet.

In July Hertz completed a 229 kW solar system at its global headquarters building in Park Ridge, NJ, and announced plans to build 11 additional solar installations totaling 2.2 MW.

A new study conducted by UC Berkeley researchers states that diesel exhaust is responsible for fifteen times more secondary organic aerosol (SOA), a major component of smog, than gas emissions per liter of fuel burned.

The study performed by UC Berkeley researchers, which has been published in the Proceedings of the National Academy of Sciences, states that the contributions to air pollution are derived from two types of fuel emissions. The authors estimate that diesel exhaust is responsible for 65-90 percent of a region’s vehicular-derived SOA, depending upon the relative amounts of gasoline and diesel used in the area.

An English company has made gasoline with only air and electricity, causing experts to call the new technology a “game changer” against climate change and a solution to the global energy crisis.

Air Fuel Synthesis, which developed the technology, uses sodium hydroxide as a filter to capture carbon dioxide from air, according to The Telegraph. Hydrogen, which is harvested from water, is mixed with the carbon dioxide to produce methanol.

Solid waste specialist Republic Services is investing $25 million to expand and improve its fleet of compressed natural gas-powered trucks for use around the St. Louis area, reports the St. Louis Business Journal.

Of the $25 million, $22 million will be spent on 72 new CNG-powered collection vehicles, the web site reports. The remaining $3 million will be used to improve infrastructure, such as fueling stations and other operational needs.

The new trucks will replace the company’s existing diesel-powered fleet. The CNG trucks will be 90 percent quieter and produce 23 percent fewer carbon emissions than the trucks they are replacing. Republic Services’ area president Tim Trost said that the long-term environmental and economic benefits will justify the company’s up-front investment in CNG.

This announcement takes the company’s investment in the St. Louis area to around $45 million this year, according to the St. Louis Business Journal. In May, the company announced plans to pump $19 million into two recycling centers in the area, effectively tripling its waste-handling capacity in the area.

Republic Services recently pledged to make nearly 70 percent of its 2012 vehicle purchases natural gas vehicles, according to NGT News. By the end of 2015 the company should have over 3,000 trucks nationwide running on alternative fuels.

In May, Waste Management announced plans to add 35 CNG vehicles to its Houston fleet by the end of 2012, and said it would open its CNG fueling station in Conroe, Texas to consumers. In August, WM launched a Louisville fleet of 25 CNG trucks — the first of its kind in Kentucky — and unveiled Louisville’s first public-access, 24-hour CNG fueling station.

Earlier this month the company opened a CNG fueling station at its Canal Winchester operations, part of a $13.5 million investment in its Central Ohio fleet. Waste Management spent $3.8 million on the fueling station, and $9.75 million on 30 CNG trucks, half of which are in operation. The rest will be operating by the end of 2012.

Arizona State University researchers have developed a new software system capable of estimating greenhouse gasemissions across entire urban landscapes, all the way down to roads and individual buildings. Until now, scientists quantified carbon dioxide CO2 emissions at a much broader level.

Dubbed Hestia after the Greek goddess of the hearth and home, researchers presented the new system in an article published October 9 in Environmental Science and Technology. Hestia combines extensive public database data mining with traffic simulation and building by building energy consumption modeling. Its high resolution maps clearly identify CO2 emission sources in a way that policy makers can utilize and the public can understand.

As part of an ongoing campaign to reduce harmful diesel exhaust that can lead to premature deaths and asthma attacks, the EPA has awarded $30 million for clean diesel projects.

Diesel engines are known as durable and fuel efficient, but older diesel engines that were manufactured before the cleaner standards emit large amounts of air pollution. Nitrogen oxide (NOx) and particulate matter (PM) are examples of this air pollution that have been linked to various health problems, such as asthma, premature death, and lung and heart disease.

Ferries running on natural gas have saved money and run for five years in Norway, nearly without incident, an executive told hundreds of diesel users today in Houston.

The talk was aimed at users of some of the largest, heaviest and most power-intensive equipment that have been tied to diesel for decades.

On the second day of the three-day High Horsepower Summit 2012 in Houston, representatives from companies that haul massive loads from mines, run trains, operate oil field drilling equipment or have fleets of heavy-duty trucks, heard the case for using natural gas over diesel.

Oscar Bergheim, operations manager for Norwegian ferry operator the Fjord1 Group, said that switching five vessels to natural gas has made sense.

“In the beginning, we thought the maintenance costs would be somewhat higher than on the Diesel engine,” Bergheim said. “The history has shown that the cost from having a gas engine is about the same as for a Diesel engine and it is very popular for our staff to work on these engines. Everything is clean, it’s high-tech.”

Users of some of the world’s bulkiest, most powerful vehicles got an earful Wednesday about the cost benefits of natural gas over diesel fuel.

“This really has turned the world upside down as far as fuel and economics,” said Erik Neandross, CEO of Gladstein, Neandross & Associates, which organized the High Horsepower Summit at the Royal Sonesta Hotel.

For example, Neandross said a single mining truck could save about $500,000 annually by using natural gas instead of diesel.

With natural gas prices running close to $2 cheaper for the energy-equivalent of one diesel gallon of fuel – and with gas producers pronouncing a steady supply of the resource for decades to come – the hundreds of attendees were eager to hear about the possibilities for everything from oil field machinery to trains to massive trucks used for hauling loads of mined material.

The company said these new leased vehicles replace its oldest diesel trucks and give it one of the largest private natural gas fleets in Southern California.

99 Cents Only Stores® recently announced it has leased 40 new compressed natural gas-powered tractors from Ryder to replace its oldest diesel-burning units. These CNG rigs make its fleet one of the largest private Class-8 CNG fleets in Southern California, according to the company.

“We are pleased to announce that we not only plan to continue offering our valued customers the best selection of products at the lowest possible prices, but have also made a commitment to our community and global environment by converting a significant portion of our delivery trucks to compressed natural gas,” said CEO Eric Schiffer. “We expect to reduce the carbon footprint of the fleet and its CO2 emissions by up to 25 percent. This will positively impact both our customers and the communities our stores serve.”

The new trucks will be used to make deliveries to the 165 stores in Southern California and to pick up goods from vendors. Ryder also will provide maintenance for the vehicles.

“We are confident that this new equipment is well suited to service our 165 Southern California stores, many of which are in densely populated areas,” said Jim Parros, senior vice president of Logistics for the company. “We chose to work with Ryder for a number of key reasons, none more important than our confidence in their capabilities to provide maintenance for the new CNG engine platform and their commitment to service, which is particularly critical when dealing with new technology.”

The company was founded in 1982 and has expanded to 302 stores: 221 in California, 37 in Texas, 29 in Arizona, and 15 in Nevada
