  • Physicochemical, spectroscopic and thermal properties of microcrystalline cellulose derived from corn cobs

    Background:Low-cost and suitable microcrystalline cellulose powders for use in the pharmaceutical industry can be derived from agricultural residues. Most commercial microcrystalline cellulose powders are produced from dissolving pulp obtained from expensive hard woods using concentrated acids. α-Cellulose was extracted from an agricultural residue (corn cob) using a non-dissolving method. ...

  • Corn cob characteristics in irrigated central great plains studies

    Escalating fossil fuel cost and concern over global climate change have accelerated interest in cellulosic feedstocks, such as corn (Zea mays L.) cobs, for liquid fuel production. Little information is available about this plant organ. We compiled and summarized available cob data from several recent field studies in the Central Great Plains. Data were collected from two locations in Colorado and ...

  • Recycling of raw corn cob residues as an agricultural waste material for ammonium removal: kinetics, isotherms, and mechanisms

    Corn cob is an agricultural by-product worldwide available in large amounts. In this study, the potential of raw corn cob as a natural lignocellulosic waste material of no economic value was investigated for the removal of ammonium ions from aqueous solution. Sorption capacities of raw granular corn cob (GCC) for ammonium ions were evaluated in simulated and actual wastewater samples. The FT-IR ...

  • Corn Production in the Bowen Food Basin - Case Study

    In Bowen, Queensland, in 2010, Hibrix was compared with a high NPK mineral fertiliser program for the production of maize cv. Hycorn 675IT on an alluvial sandy loam soil irrigated via sub-surface drip tape. At commercial harvest, cobs from 20 randomly selected plants per plot from were harvested, weighed and the length, girth at the cob base and length of tip not filled with kernels was measured. ...

  • Turning field residue into ethanol feedstock

    Darrin Ihnen is looking at corncobs in a new light. Once left on the fields to rot, Ihnen is now harvesting the cobs along with the corn from 4,000-acres on his farm in Hurley, South Dakota - hoping to turn the field waste into income producing feedstock for making ethanol. Typically corn is harvested by a combine that strips the ears from the corn stalks, separates the grain from the ears and ...

  • Redefining ag-wastes as coproducts

    Alan Doering doesn’t have the word “waste” in his vocabulary. As the scientist heading up the Agricultural Utilization Research Institute’s (AURI) coproduct utilization program, Doering sees crop residue, agricultural processing leftovers and biomass as products with value worth exploring. “Every leftover or coproduct has a value,” Doering says. “Our goal is to find the best use with the highest ...

  • Pesticides manufacturer meets blend regulations using rotary batch mixers

    When Bonide Products, Inc., moved into new and larger facilities, an important consideration was the selection of mixing equipment for its granular and powdered pesticides, insecticides and herbicides. "Our business is pretty heavily regulated by the (U.S.) Environmental Protection Agency and by the states," says Jim Wurz, president, "and we have to meet a guaranteed analysis for our products. If ...

  • Worming the way to finished compost

    SCREENING AND GRINDING When materials from CR&R and other generators are unloaded, a preliminary screening separates out nonorganic contaminants.    Even though there are source separated programs in places like Temecula and Lake Elsinore, there is the occasional appearance of plastic and glass that needs to be sorted out. Next, Bodlak’s crews put materials through a Vermeer tub ...

  • APL in the Field: Powertainer install at UNM Morris - University of Minnesota, Morris, Minnesota - Case Study

    In a partnership with Cummins Inc., APL worked with University of Minnesota in Morris to develop a prototype shipping-container-based 100 kW genset running on Minnesota's plentiful agricultural waste corn cobs. With the help of a grant from the California Energy Commission, APL is currently partnered with University of ...
