Midwest Bio Systems (MBS) provides high quality composting equipment, supplies, and expert guidance world-wide to create new income streams from your waste issues -- crop residues, manures, sawdust, food wastes, ground wood chips, metropolitan lawn waste (grass, leaves, shrub and tree trimmings), and the like. Our comprehensive approach, together with our sturdy, dependable, and long-lasting Aeromaster Compost Turners, water trailers, and compost tea extractors, puts waste management science and technology together into an unbeatable package for you.

Our Aeromaster compost turners feature advanced drum and tine design for superior material blending into peaked windrows, thorough aeration, and CO2 release. Peaked windrows form higher quality compost with a shorter production cycle. They also maintain internal windrow temperature and shed water better than windrows flattened on top.

The retractable drum assembly lifts out of the windrow hydraulically for windrow profile inspection and easy exit from the windrow. The hydraulically adjustable rear axle adjusts on the go six inches up or six inches down for optimum drum height when moving through the windrow. This also prevents an anaerobic layer from forming under the windrow.

Our mechanical watering system inoculates the decomposing materials with sufficient moisture for maximum biological activity and material breakdown into that all-important crumb structure inherent in highest-quality compost.

We bring manufacturing expertise, and state-of-the-art composting, consulting, and training experience to bear on waste issues world-wide! Visit our website at www.midwestbiosystems.com today. And yes, we do make high-quality compost ourselves!

Aeromaster turners offer efficiency options for composters

Aeromaster compost turners from Midwest Bio-Systems are designed for cost-efficiency and reliability, and now come with optional tool boxes attached. The company says these new tool boxes will keep windrow monitoring instruments handy for the operator and house the tools needed throughout the workday to make critical turner adjustments and ensure consistency in the production of compost.

New tine design

New tine design

Clean-Sweep tines use a near-concentric edge, so that windrows are rotated more completely, resulting in more thorough gas exchange and rotation of material between “hot” and “dormant” areas of the pile. An additional benefit is lower maintenance and longer life of the tine due to reduced, more even wear. The improved material handling provided results in higher, more consistent fertility content and lower toxicity in the resulting compost.

Tea extractor

Tea extractor

The TE500 Tea Extractor features a 1,500 gph capacity (starting with 500 gallons of water and a small amount of high quality compost). These units extract soluble minerals, humus, and microbes from high quality compost, allowing for an easy liquid delivery of probiotic soil microbes and nutrients to crops. No microbe activators are added in the extraction process of the tea, which gives end product a useful life of two to three months. Only a small amount of Aeromaster Tea Activator is added just prior to the application of the compost tea to activate soil microbes. The delay in microbe activation preserves the microbial diversity of compost by stimulating microbial growth only when the compost tea is applied to soil.

New tine design enhances compost results

New tine design enhances compost results

Midwest Bio-Systems (MBS) has introduced the Clean-Sweep tine, designed to further enhance the results generated by the company’s composting systems. Due to a near-concentric edge, these tines rotate windrows more completely, resulting in more thorough gas exchange and rotation of material between “hot” and “dormant” areas of the pile. An additional benefit is lower maintenance and longer life of the tine due to reduced, more even wear. The improved material handling provided results in higher, more consistent fertility content and lower toxicity in the resulting compost.

Tea extractor added to Aeromaster line

Tea extractor added to Aeromaster line

Midwest Bio-Systems recently added the TE500 Tea Extractor to their line of Aero-master equipment. Units include a 1,500 gph capacity (starting with 500 gallons of water and a small amount of high quality compost.) Like most compost tea brewers, these units extract soluble minerals, humus, and microbes from high quality compost, allowing for an easy liquid delivery of probiotic soil microbes and nutrients to crops. No microbe activators are added in the extraction process of the tea when using the TE500, which gives the tea a useful life of two to three months. Only a small amount of Aeromaster Tea Activator is added just prior to the application of the compost tea produced by the TE500, to activate soil microbes. The delay in microbe activation preserves the microbial diversity of compost by stimulating microbial growth only when the compost tea is applied to the soil, rather than pre-stimulating microbial growth during either the extraction or brewing process.

Compost turners provide high production with one person operation

Compost turners provide high production with one person operation

SP series compost turners include the SP-170 (shown) and the SP-155, and are designed for self-propelled applications. The SP 170 is designed for large volume facilities handling up to 2,670 cubic yards-per-hour, and is offered in two-or four-wheel-drive, with both a work speed and a road speed for easy site manoeuvra-bility. Units have an onboard computer system to monitor critical functions and two cameras to give operators a great view of the turning drum and tail boom. A short turn radius makes this machine easy to manoeuvre at the end of rows. The SP-170 is powered by a 305-hp, Tier 3 engine and features total hydraulic control for propel and drum motion. The SP-170 uses a 14-foot drum and can be configured with either an on-board water tank or a hose reel water system. Units are cab controlled with numerous computer features, and are the ultimate in operator ease and convenience. The award-winning model SP-155 self-propelled straddle turner is designed for operations exceeding 30,000 tons per year witha drum of 13 feet which, with side scoops, will turn windrows up to 15 feet wide and six feet high. These units will turn over 3,800 cubic yards-per-hour when operating at a speed of 1/2 mph, weighs 30,000 pounds and are approximately 22 feet by 20 feet, with a speed of 15 mph for travelling when not in the windrow.
