    Representatives of 16 countries attended the 11-13 July Regional Forum for National Designated Entities in Asia organized by the Climate Technology Centre and Network (CTCN) of the United Nations Framework Convention on Climate Change (UNFCCC) to promote information exchange and capacity building on climate technologies and finance.

  • Background: Mass cultivation of algae for biofuel production has focused on the use of open ponds or closed bioreactors. Both approaches depend upon routine liquid culturing of the algae and require the removal of large quantities of water at the time of cell harvesting and subsequent extraction of desired products. This invention proposes the use of porous inert membranes to support the growth and subsequent harvesting of the algae.

  • Seambiotic is the first in the world with proprietary technology for growing marine microalgae in open ponds using flue gas and recycled seawater from power plant. Seambiotic is also the first in the world to successfully connect directly to a power plant’s smokestack for direct consumption of CO2. The Company currently holds patent applications on the technology. Seambiotic was initially established to produce and sell Omega 3 fatty acid products from marine microalgae.

    What is Micro-algae

    Micro-algae are a group of unicellular or simple multicellular fast growing photosynthetic microorganisms that can conserve CO2 efficiently from different sources, including the atmosphere, industrial exhaust gases, and soluble carbonate salts. Micro-algae act as a major system for converting atmospheric CO2 into lipids under sunlight and increase the output of algal oil. The enzyme acetyl Co-A carboxylase (ACCase) from micro-algae catalyzes the key metabolic step in the synthesis of oil in algae.

  • Sectors

    The use of Liquefied Natural Gas (LNG) in transport is a suitable option to power large long-distance trucks in areas where gas is transported as liquefied natural gas because there are indigenous gas supplies and no gas network. The use of LNG in passenger cars is far less viable because on average passenger cars stand idle more often, which would give rise to high evaporative losses.

  • Objective

    The need to reduce the impacts of deteriorating quality of public waters (particularly enclosed water bodies, etc.) as a result of climate change, in areas that may face declining sanitation conditions. Particularly applicable in response to the need to mitigate impacts in regions where water pollution is occurring due to urban population growth associated with economic growth, or due to rapid industrial development.

  • Objective

    Solar thermal technology can be used to provide heating for domestic or industrial uses. A solar heating system can capture the sun's radiation and use it for both hot water heating and supplement home heating by piping hot water through traditional or modern radiators, furnaces, or use it in hydronic system for in floor radiant heat. In most cases solar should be used with conventional power as a supplement, this way you never have to rely completely on the sun shinning. An important part of a home solar system is the controller. The controller senses input and output temperatures.

  • Sectors

    Rainfall can provide some of the cleanest naturally occurring water that is available. There is considerable scope for the collection of rainwater when it falls, before huge losses occur due to evaporation, transpiration, and runoff and drainage - before it becomes contaminated by natural means or man-made activities. Rainwater harvesting is a particularly suitable technology for areas where there is no surface water, or where groundwater is deep or inaccessible due to hard ground conditions, or where it is too salty or acidic.

    In Bangladesh improved sanitation consists largely of latrines and septic tanks. Human waste from these facilities is dumped untreated in waterways or down drains, causing alarming health risks to all. In the Faridpur district of Dhaka, Practical Action is working with the government, pit emptiers the private sector, local development partners and other organisations to install a faecal sludge management system.
