NSF To Manage BPI Compostable Logo

NSF International, a global certification organization based in Ann Arbor, Michigan, began administering the “Compostable Logo” for the Biodegradable Products Institute (BPI) in January 2012. BPI made the move in order to handle a reported fivefold increase in compostable products certifications. Based on ASTM D64000 and ASTM D6868 standards for compostability, NSF will verify manufacturers claims in large-scale composting facilities after companies submit products and testing data to substantiate biodegradation, disintegration and the absence of eco-toxicity in their products. Following certification, manufacturers, authorized distributors and resellers may license BPI’s “Compostable Logo” for marketing claims on products including compostable bags, food service items and packaging materials.

New Trommel On The Block

Screen USA announces the addition of the TROM6090 to its full line of American-manufactured portable screening equipment. The TROM6090 will screen approximately 60 to 90 cubic yards/hour; for dry material, it has exceeded 120 cy/hour. Screen USA, based in Smyrna, Georgia, manufactures its portable shaker screens, trommels, starscreens, wood grinders and conveyors in the U.S. These diverse technologies enable the company to match the most appropriate products for customers’ particular applications. The TROM6090 was developed to fill a gap in the company’s trommel screen line.

Integrated Ad Project Breaks Ground

Quasar Energy Group and Ohio State University (OSU) have broken ground on a pilot-scale “integrated anaerobic digestion system” (iADs) in Zanesville, Ohio. The patent-pending technology was developed by OSU’s Dr. Yebo Li and couples Quasar’s liquid AD technology with solid-state AD to increase energy outputs, expand the feedstock base and broaden potential market application. A primary feature of the system is the ability to accept high solids material such as corn silage and yard and food waste. “iADs will allow Quasar to accept and process a wider range of high solids feedstocks including off spec and major market recall material, expanding our business to offer customers a full-service solution to their waste management challenges,” said Quasar President Mel Kurtz.

Hybrid Trommel

Komptech hybrids feature all-electric drive with an auxiliary onboard diesel generator and the capacity to run directly off the electrical power grid. The all-electric drive is more efficient, cleaner and quieter — with the dual-power feature enabling equipment to operate at sites with or without ground power — and the generator is more fuel-efficient than conventional diesel and hydraulic units, says the company. Komptech offers hybrid drives in its windsifters, star screens and trommels. A diesel generator burning about 1.5 gallons/hour of fuel is capable of processing around 200 yards of finished product within the same timeframe. In addition to fuel savings, operators can cut back significantly on maintenance costs, notes Komptech.

Composting Disposable Nappies

OCS Ltd., an international services company, signed a global sponsorship agreement with Kimberly-Clark Corporation that gives the U.S. headquartered manufacturer of Huggies brand disposable diapers the right of first refusal to sponsor OCS’s Envirocomp composting facilities as they are installed around the world. OCS uses the HotRot Organic Solutions (NZ) Ltd. composting technology, an enclosed U-shaped vessel with a central tine bearing shaft. OCS plans to establish Envirocomp facilities in the United Kingdom, the Republic of Ireland, Australia and mainland Europe, while expanding operations of its New Zealand facilities over the next 18 months. Envirocomp’s program entails collection of used disposable diapers from households and commercial facilities (preschools, care facilities) and delivering them to one of its composting sites. In 2009, Huggies brand diapers sponsored the first commercial nappy composting facility in Christchurch, New Zealand. Within the first year of operation, more than 15,000 diapers a day were mixed with green waste supplied by the local councils and composted.

Mini Skid Steer

Vermeer Corporation completes its family of mini skid steers with addition of the S450TX. With both diesel and gasoline engine options, the new unit is well suited for rental customers as well as landscapers and general contractors who need a compact machine that can perform various tasks, notes the company. The S450TX can accommodate a wide range of attachments. It has a 500-pound SAE-rated operating capacity with a 1,430-pound tipping capacity. Vermeer has incorporated a four-pump hydraulic system, which provides performance and efficiency when powering attachments. A single pilot-operated joystick is now integrated into the S450TX platform, making it easy to maneuver and operate.
