Cortec Partners With Mirel
Cortec Corporation, a plastic film manufacturer in St. Paul, Minnesota, has selected Mirel bioplastic for a new line of film products. Mirel’s biobased and biodegradable alternatives to petroleum-based plastics are products of Telles, a joint venture of Metabolix and Archer Daniels Midland. Through a mutual development and commercialization collaboration, Cortec and Telles have advanced proprietary processing and extrusion methods resulting in the first commercially viable finished flexible film products made from the new Mirel P5001 film-grade resin. Cortec is launching two new products based on Mirel P5001 – EcoOcean and Eco Works AD. EcoOcean is for marine biodegradable markets and Eco Works AD is designed to meet the demands of anaerobic digestion systems. Cortec’s biodegradable films are available in more than 70 countries worldwide. EcoOcean and Eco Works AD will be available through these sales channels upon launch. “Eco Works AD is the result of more than 13 years of development work and finally achieves the high renewable content that was previously unattainable in a flexible film that has a range of disposal options after use,” says Boris Miksic, Cortec’s president and CEO. and

Eco-Safe Digester
The new Eco-Safe Digester from Marathon Equipment Company is a food waste decomposition system that uses a highly refined formula of microorganisms to break down organic waste into a liquid that can be safely flushed down the drain, enabling the effluent to return to the ecosystem as water, according to the company. The equipment is designed to process all food waste streams, including meat, poultry, fish, grains, dairy products, fruits and vegetables. “The Eco-Safe Digester is an ideal solution for high-volume food waste generators like supermarkets, hospitals, schools, prisons, restaurants and hotels,” says Geoff Apthorp, Vice President of Engineering and Business Development at Environmental Solutions Group, Marathon’s parent company.

Biomass Super Shredder
The new Biomass Super Shredders from West Salem Machinery (WSM) combine the efficiency of a high-speed mill with the durability of a heavy-duty grinder. Available with rotor widths from 60 inches to 88 inches, these machines deliver higher tip speed for smaller, consistent fiber sizing, increased screen area for more throughput and flexible, interchangeable tooling, says WSM. The largest model, the 4888S, features a 48-inch in diameter by 88-inch-long rotor and operates with 400 to 800 HP to convert high volumes of preprocessed biomass materials. The Super Shredder has production rates of up to 100 tons/hour, eliminating the need for multiple machines. WSM Biomass Super Shredders include modular sizing screens, dual pivoting hydraulic housing and reversible/replaceable hammer tips for reduced maintenance and operating costs.

Backhus Introduces New Machinery
With more than 25 years serving the composting industry, Backhus EcoEngineers recently announced the Series 21, a completely newly designed windrow turner, and the Backhus DC 50, a totally self-contained, automatic and dynamic composting system designed for an average annual throughput of 500 tons. Both products were rolled out at a three-day event in July to introduce the newest additions of the company’s product line to international clients, dealers and agents. The 21.50 is the company’s 800th machine and the first Backhus turner since 1988 to be mounted on wheels, which can also be replaced by a track drive in about three hours. The machine is designed to turn compost efficiently while minimizing dust.

The “DC” in the Backhus DC 50 stands for “dynamic container” – dynamic because it doesn’t only aerate the input material, it also utilizes agitators to ensure complete homogenization. A striking feature of the BACKHUS DC 50 is its compactness, notes the company. To start the composting process, a power outlet is the only requirement. Everything else is integrated, and additional steps other than filling the container with organic material are not necessary. “We aimed at a solution that could provide the two most essential features composters need: thorough homogenization and proper aeration,” says Backhus founder and CEO Friedrich Backhus. “An increased demand for small-scale composting systems that can effectively control emissions in order to operate even in densely populated areas were other key requirements that led to the development of the Backhus DC 50.”
