Water Bioremediation

‘BAGS’ System

One of MBD Energy’s most valuable technologies, its Biological Algal Growth System (‘BAGS’) offers capacity to rapidly synthesise captured smokestack CO2 emissions, on a continuous basis, in a fully enclosed proprietary plastic membrane.

Relatively low-cost to produce, deploy and operate – the BAGS membranes provide the algae with a controlled environment in which they flourish – typically doubling in mass every 24 to 48 hours.

The rapid growth of algae is enhanced by a constant flow of captured CO2 (and other problem greenhouse gases such as NOx and SOx) which are dissolved into nutrient-rich waste water that slowly circulates through the membranes.

The process allows harvesting on a continuous basis. The algae biomass is dewatered and processed in accordance with intended end use i.e. biofuels (including oils and briquettes), nutrition or fertiliser production.

The system is modular and scalable. It is sufficiently compact to utilise a comparatively small land footprint with commercial-scale facilities expected to occupy areas up to 2000 hectares depending on the scale of emissions. Typically, vacant ‘buffer land’ around the perimeter of an emitter’s industrial plant is more than sufficient.

Being low to the ground, and containing no biohazards or organisms that might pose a threat to local ecology and biodiversity – the ‘BAGS’ installations have a very low environmental impact

Transport Fuel The developed economies of the world are heavily dependent upon liquid fuels and gas to meet their transport energy needs. Most of this fuel is derived from the increasingly costly and logistically challenging mining of crude oil, coal and gas.
