Description
An algae bioreactor is a machine that utilises carbon dioxide, wastewater, and algae to produce biomass and oxygen. Thereby it helps trap air, water, and solid waste pollution. Just two algae bioreactors, installed in Pulchowk and Jawalakhel in Kathmandu, have so far produced more than 12,000 litres of oxygen. Currently, efforts at scaling up are ongoing, both via laboratory tests and in conversation with the relevant municipal authorities.
Over the last two decades, the growing number of motor vehicles, rising population due to migration, and greater waste generation have given rise to a range of environmental challenges in Nepal’s capital, Kathmandu. The air is more polluted, the water table more toxic, and solid waste is piling up at dumpsite
An algae bioreactor is a machine that utilises photosynthesis, carbon dioxide (CO2), wastewater, and algae to produce biomass and oxygen. It uses the flue gas emissions from industries, factories, boilers, hospitals, waste incinerators, and any chimney to trap the CO2 in the algal biomass. The nutrients required for the algae to grow come from wastewater. Thus, it helps trapping air, water, and solid waste pollution within the system, and in the process helps in the mitigation of climate change.
