  • Have humans tilted the climate books out of balance?

    In the great book-keeping of climate change, scientists have just discovered a big mistake. They have been wrong, they now think, to count on the mountains, the plains, the forests and the grasslands as an agency that slows climate change by absorbing carbon dioxide. It does absorb carbon dioxide. But the chilling news is that  ...

  • Have Your Steak and Eat It, Too

    In our recent feature, “Has Meat Met Its Match?,” writer Rowan Jacobsen explores ways people can (now and possibly in the future) reduce the environmental and food security impacts of their diets, including entomophagy (bug-eating), synthetic meat and vegetarian substitutes. If none of those fits your needs, there are plenty of other ways ...

  • Process parameters analysis for the vermicomposting of shredded paper using Pheretimoid Spp.

    This study was to assess the effect of new species of earthworms, Pheretimoid Spp., on vermicomposting and compare the quality of vermicompost against compost produced from the same mix ratio of shredded office paper (SOP) together with grass clippings (GC) and cow manure (CM). Two composting experiments were setup in rotary drum composters namely: 1) composting of SOP, GC and CM followed by ...

  • Co-digestion of bovine slaughterhouse wastes, cow manure, various crops and municipal solid waste at thermophilic conditions: a comparison with specific case running at mesophilic conditions

    A co-digestion process was evaluated when mixing different ratios of agro-industrial residues, i.e. bovine slaughterhouse waste (SB); cow manure (M); various crop residues (VC); and municipal solid waste (MSW) by anaerobic batch digestion under thermophilic conditions (55 °C). A selected study case at mesophilic condition (37 °C) was also investigated. The performance of the ...

  • Nutrient transport characteristics of livestock manure in a farmlan

    Background :Livestock excretions containing high concentration of nutrient, pig liquid fertilizer, and cattle manure were applied to agricultural land. The characteristics of nutrient transport were examined in surface runoff and groundwater by an artificial rainfall event at real scale field site. Also, the effects of the artificial rainfall event on the characteristics of residual soil after ...

  • Anaerobic co-digestion of cattle manure with rice straw: economic & energy feasibility

    Rice straw (RS) is one of the most abundant wastes generated in Valencia (Spain). Traditional waste disposal methods are harmful to the environment. The straw burning emits large amounts of toxic air pollutants and the straw burying produces uncontrolled anaerobic fermentation in the soil. The aim of this research was to evaluate the feasibility of cow manure anaerobic co-digestion with RS in a ...

  • New Mexico Business Weekly Passing biogas: R-Qubed project converts cow manure to methane

    Some locals sarcastically joke that the stretch of dairy farms along Interstate 10 south of Las Cruces should be re-named “Buenos Aires” (fresh air). It’s a reference to a less than aromatic sector of I-10 in southern New Mexico, not a reflection on the capital of Argentina. But that soon might change, thanks to a US$72 million plan by R-Qubed Energy Inc. of El Paso to build ...
