    Renewable energy & fish production

Advanced fish farming to secure the responsible use of thermal heat generated from Organic Biogas Platform (Anaerobic Digestion)

Renewable energy is energy which comes from natural resources such as sunlight, wind, rain, tides, geothermal heat, and agricultural commodity wastes and municipal wastes, which are renewable (naturally or sustainably replenished). Climate change concerns, coupled with high oil prices, peak oil, and increasing government support, are driving increasing renewable energy legislation, incentives and commercialization.

All forms of energy are expensive, but as time progresses, renewable energy generally gets cheaper, while fossil fuels generally get more expensive. Al Gore has explained that renewable energy technologies are declining in price for three main reasons:
  • First, once the renewable infrastructure is built, the fuel is free forever. This includes agricultural and municipality wastes to energy sources. Unlike carbon-based fuels, the wind and the sun and the earth itself provide fuel that is free, in amounts that are effectively limitless. Human municipal wastes is 'endless' too, with sustainable availability everywhere.
  • Second, while fossil fuel technologies are more mature, renewable energy technologies are being rapidly improved. So innovation and ingenuity give us the ability to constantly increase the efficiency of renewable energy and continually reduce its cost.
  • Third, once the world makes a clear commitment to shifting toward renewable energy, the volume of production will itself sharply reduce the cost of each windmill and each solar panel, while adding yet more incentives for additional research and development to further speed up the innovation process.
While most renewable energy projects and production are large-scale, renewable energy technologies are also suited to small off-grid applications, sometimes in rural and remote areas, where energy is often crucial in human development.

Concomitantly with the energy crisis, it is becoming clear that the World faces other, additional crises, occurring simultaneously. Those are the crises of:
  • Diminishing fresh water resources, worldwide
  • Collapse of ocean capture fisheries, worldwide
  • Agricultural commodities production
Fish production integrated with renewable energy derived from waste-to-energy plant: including integration with intensive irrigation (in greenhouses, in cold climates), and based on:
  • The Energy center providing electricity and waste heat to enable year-round production of fish under any climatic conditions (in closed systems).
  • The Fish production system discharges sludge, and the Fish Processing Plant provides scrap, both converted to Liquid Fertilizer by the bio-digester, to be used by the greenhouse to improve vegetable production, or to produce biodiesel.
  • CO2 emitted in the process of fish respiration can optionally be diverted, as CO2-rich warm air, into the vegetable greenhouse atmosphere to facilitate photosynthesis at optimal temperatures.
Fish production integrated with irrigation of biofuel plantations: Using APT's Fish Farming and Irrigation (IFFI) technology, dual use of water is practiced, first for fish production, then for biofuel crops such as sugarcane. Fish sludge and fish processing scarp are used to produce biodiesel or Fish Fluidized Fertilizer in order to increase Sugar Plantation efficiency. Bioethanol is an alcohol made by fermenting the sugar components of plant materials and it is made mostly from sugar and starch crops.

Fish production integrated with irrigation of fish feed ingredients and biofuel production. Fish Farming and Irrigation (IFFI) entailing dual use of same water first for fish production then for irrigation, pumping one time for the two crop systems, as is being used in Israel for decades in open areas agriculture by private sector and Public Private Participation schemes. Protein-rich grain meals (soy, safflower seed; corn; etc) are used for pelletized fish feeds and oil extraction for human consumption and biodiesel production. APT project in El Salvador:

Fish production in conjunction with hydroelectric power generation: Fish production in cages in the water reservoirs and dams, and in the water discharged from the hydroelectric turbines to increase income generation, employment and sustained fish output - APT project in Peru:

Fish production and Biodiesel: Biodiesel is made from irrigated vegetable oils, fish scrap recycled greases, obtained after processing the fresh fish fillets for the high-end seafood consumers. Biodiesel can be used as a fuel for vehicles in its pure form, but it is usually used as a diesel additive to reduce levels of particulates, carbon monoxide, and hydrocarbons from diesel-powered vehicles. Biodiesel is produced from oils or fats using transesterification and is the most common biofuel in Europe.

In such complexes, APT provides the aquaculture technology & services.
