Digester Effluent As Inoculant

A new process — q-bio adsorption technology — binds nutrient-rich anaerobic digester effluent with woody waste materials such as yard trimmings to create a high value compost product. Introduced by quasar, q-bio reduces composting time by up to 33 percent while achieving an optimal carbon to nitrogen ratio, according to Bruce Bailey, quasar vice president, Technical Affairs. The “Class A” equivalent product will be made at quasar’s digesters in Ohio. www.quasareg.com

Weltec Biopower's MULTIMix unit pulverizes fibrous and sticky input materials such as grass silage, solid manure and cosubstrates, increasing their surface area for more rapid decomposition in the digester.

Rugged Mixer For AD Systems

A “rugged liquid input system” from Weltec Biopower pulverizes fibrous and sticky input materials such as grass silage, solid manure and cosubstrates, increasing their surface area for more rapid decomposition in the digester. The MULTIMix unit also separates contaminants such as rocks and metals prior to input, decreasing risk of damage to the pumps and agitators. The pulverizing process is supported by a screw system that size-reduces the fibers. The MULTIMix can be installed at existing anaerobic digesters by placing it between the feedstock hopper and the tanks or fermenters. www.weltec-biopower.de

Komptech increased its manufacturing capacity by opening a new plant in Germany and expanding its existing facility in Ljutomer, Austria, to meet growing demand for its machines.

Expanding Manufacturing Capacity

To meet growing demand for its machines, Komptech increased its manufacturing capacity by opening a new plant in Germany and expanding its existing facility in Ljutomer, Austria. The Austrian plant can build six large composter turners, shredders or other machines at the same time, according to Komptech, as well as provide better economies of scale. The company adds that the expansion is helping meet demand for its Topturn compost turner, mainly in the North American market, which Komptech notes is its largest single market for that machine. It is focusing on servicing the market in terms of product design, production capacity, parts and service. www.komptechusa.com

Compost Containment System

Filtrexx domestically manufactures a patented tubular mesh containment system for composted mulch or humus used in a variety of applications, including sediment and erosion control, pollutant removal, Low Impact Development and agricultural applications. Compost-based filter media is locally sourced from a nationwide network of over 130 Filtrexx® Certified™ Manufacturers and Installers. In the past year, the company invested in 15 new manufacturing facilities across the U.S. to increase availability while decreasing delivery time and freight costs for customers in the field. www.filtrexx.com

The DustBoss® DB-R Ring™ from Dust Control Technology is designed for dust suppression at material discharge points, such as conveyors.

Dust Control Ring

The DustBoss® DB-R Ring™ from Dust Control Technology, designed for dust suppression at material discharge points, is now available in four new sizes (30-inch, 48-inch, 54-inch and 72-inch models). The stainless steel rings are mounted at the end of conveyor belts. They are tested to withstand pressures of up to 900 PSI, with brass atomizing nozzles that deliver millions of 50 to 200 micron droplets per minute. An optimal booster pump can be added to increase water flow and pressure, and units can be equipped with a two-way valve to provide manual control over water flow. www.dustboss.com

Herbicide Bioassay

Woods End Lab upgraded its herbicide bioassay to add risk evaluation for plant subcategories: sensitive, affected and insensitive. The new protocol is based on the lab’s Compost Matrix, a quality certification system developed for composters “that enables skillful placement into best use categories, or in the case of herbicide residues, helps avoid exposing a market segment to undue risk,” explains Will Brinton of Woods End. Application rate thresholds are provided. The lab also developed a method to screen raw source ingredients before they are added to compost mixes. www.woodsend.org.
