Reduce GHG emissions

Reduce GHG emissions

  • Improvement of Agri-food processes

    Type: 
    Technology
    Sectors:
    Objective:

    The agri-food industry comprises an integrated complex production chain which ranges from the primary agriculture to the mature food and beverage sector. It is considered as one of the largest sectors  worldwide with significant contribution to the economic advancement of nations and major social impact.

  • 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.

  • Straw ammoniation and silage

    Type: 
    Technology
    Sectors:
    Objective:

    Straw ammoniation is a process by which low-value forage such as corn stalks, rice straw, wheat straw, and straw of other crops is ammoniated. Adding liquid ammonia, urea, or ammonium bicarbonate as ammonia sources result in the straw lignin being completely degraded, while the nutrients are enhanced. It is made more easily digestible by rumen microorganisms, which increases the digestibility of forage.

  • Mid-season drainage (rice)

    Type: 
    Technology
    Sectors:
    Objective:

    Mid-season drainage involves the removal of surface flood water from the rice crop for about seven days towards the end of tillering. The duration of the dry period must be long enough for rice plant to experience visible moisture stress. 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.

  • Iron Nutrient Particles to Seed Algae (Phytoplankton) Growth

    Type: 
    Product
    Objective:

    Background: Algae are responsible for converting carbon dioxide into oxygen. However more than 20% of the world\\\'s oceans lack algae growth. The essential nutrient that is lacking in the algae-deficient surface waters is iron. However this iron must be (i) on the surface so that the algae can convert carbon dioxide to oxygen via photosynthesis and (ii) biologically available so that algae can use it. Technology Description: This technology describes the composition of and the method of production for water-buoyant particles that contain bioavailable iron.

  • Carbon-negative nanoparticle production

    Type: 
    Product
    Objective:

    Carbon Upcycling Technologies is at an early stage of developing a process that sequesters carbon from CO2 in the form of a modified graphene product. The process itself requires a concentrated CO2 stream(such as the waste gas from coal fired power generation facilities refineries and other processing plants)as well as another solid carbon feedstock such as graphite or coal. Active carbon sites are generated on the solid carbon feedstock by repeatedly breaking molecular bonds on the solid. The active carbon reacts with the gaseous CO2 molecule.

  • Reduced tillage (rice)

    Type: 
    Technology
    Sectors:
    Objective:

    For upland crops, reduced tillage technology for paddy rice involves planting or transplanting directly into the soil with minimal prior tillage in the residues of the preceding crop. 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.

  • Chemical fertiliser amendment (rice)

    Type: 
    Technology
    Sectors:
    Objective:

    Emissions of GHGs are affected by the amounts and types of fertilisers applied, so judicious choice of fertiliser application rates and fertiliser types can reduce emissions. 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.
