Enteric fermentation

Enteric fermentation is a digestive process by which carbohydrates are broken down by microorganisms into simple molecules for absorption into the bloodstream of an animal.

  • High Rate of Microbial Production of N2O for Energy Generation

    Type: 
    Product
    Technology:

    Stanford researchers have developed a method for converting ammonia in wastewater into nitrogen gas while simultaneously generating power in a bioreactor system. This method produces energy from carbon and nitrogen waste and provides significant cost and energy savings over current options.

  • Fertiliser, manure and straw management (rice)

    Type: 
    Technology
    Sectors:
    Objective:

    Fertiliser and manure management in rice fields are important methane mitigation technologies. The fertiliser management mitigation option includes changes in: fertiliser types; fertiliser nutrient ratios; the rates and timing of applications; and use of nitrification inhibitors to reduce methane emissions by affecting methanogenesis in rice fields. Rice cultivation is responsible for 10% of GHG emissions from agriculture. In developing countries, the share of rice in GHG emissions from agriculture is even higher, e.g., it was 16% in 1994.

  • Livestock management

    Type: 
    Technology
    Sectors:
    Objective:

    Livestock are important sources of methane. The United States Environmental Protection Agency calculated that livestock, especially ruminants such as cattle and sheep, account for approximately one-third of global anthropogenic emissions of methane (US-EPA, 2006). The methane is produced primarily through the process of enteric fermentation and released through the process of eructation (Crutzen, 1995). In addition, N2O emissions are generated by livestock through secretion of nitrogen through the urine and faeces.

  • Efficient Lower Cost Chemical Transformation of Lignocellulosic Biomass into Fuels and Chemicals

    Type: 
    Product
    Technology:

    Cellulosic biomass has tremendous potential as a renewable resource for the production of fuels and chemicals. It is especially promising because it is inexpensive and readily available from crop residues and forests. However it is difficult to transform into usable small molecules such as 5-hydroxymethyl-2-furfural (HMF). HMF is acknowledged widely as a key building block for renewable materials and has been highlight by the U.S. Dept. of Energy as a crucial renewable chemical.

  • Solar Cells Turn HMF to Valuable Platform Molecules

    Type: 
    Product

    Background: Photoelectrochemical cells (PECs) use solar energy to produce fuels much as nature does through photosynthesis. In a typical PEC fuels are formed by reduction reactions at the cathode. For example water can be reduced to hydrogen gas (H2) or CO2 can be reduced to methanol and methane. To complete the circuit a reaction has to take place at the anode typically water oxidation. Technology Description: However water oxidation is slow and its product O2 is not very valuable. Identifying a more useful anode reaction would improve the overall efficiency and utility of PECs.

  • Fiber Optic Gas Monitoring System

    Type: 
    Product

    VT has developed a sensor system that determines the concentration of methane in the ambient atmosphere and displays the value in real-time.

  • Methane Generator from Waste Materials

    Type: 
    Product

    A new anaerobic digestion system that naturally converts biomass waste material into methane gas is proposed by the referenced technology. Manure is used as the main input which can also be used in combination with other forms of organic waste material. Managing manure has been a persisting challenge for dairy farmers. According to the U.S. Department of Agriculture a dairy cow produces approximately 80 lbs. of manure per day. Considering that an average dairy farm can have 150 cows farmers have to manage 6 tons of manure on a daily basis.

  • Better Biomass Conversion with Recyclable GVL Solvent

    Type: 
    Product

    Background: To recover useful carbohydrates locked in biomass molecular bonds must be broken while avoiding further reaction of the resulting glucose and xylose sugars. This is a challenge because glucose can degrade quicker than it is produced. Fast hot reactions try to minimize such degradation but are impractical. Expensive catalysts and cellulose-converting enzymes (which require feedstock pretreatment) also can be used at high cost. A new milder strategy is sought to efficiently produce and preserve desired sugars.
