Environmental Challenge

The recent increase of greenhouse gas concentrations in the atmosphere is mainly due to the human activities and is almost certainly responsible for the global warming phenomenon that we have observed over the last years. This ďanthropogenic" greenhouse effect is mainly caused by the emission of CO2: more than 50% of the anthropogenic greenhouse gas emissions are carbonic gas contributing to 75% of the anthropogenic greenhouse effect. This value is rising up to 90%, only considering the industrial emissions; industries have thus interest in making the reduction of CO2 emissions a priority. Industrial processes (excluding energy industries and manufacturing industries and construction) represent one of the most important business sectors responsible for CO2 emissions, being responsible for 7% of European emissions.

Fossil fuels (gas, petroleum and coal) currently represent around 80% of the energy consumed in Europe. Unfortunately, these are finite resources and without modifying the manner we use them, our reserves will be completely exhausted in less than one century. In order to avoid this and to ensure our future, it is necessary to continuously ration our fossil energy consumption. One of the alternatives, strongly supported by the European Union, is the increase of the use of renewable energies, such as wind energy, solar energy, or biomass. Nowadays these energies represent around 10.8% of the total energy consumed in Europe. By far the biggest source of the currently used renewable energy is biomass, with a 62% contribution. The lime and glass industries consume fossil fuels and produce significant quantities of CO2.

The AGICAL+ Project

The objectives of this project were two-fold: reducing the emissions of greenhouse gases and the consumption of fossil fuel linked to glass and lime production. The project thus aimed to contribute to limiting the impact of industrial activities on climate change. This would be achieved by capturing CO2 in the flue gasses using microalgae cultures, and then processing these microalgae to extract biofuel, to be used again in the product process to reduce the consumption of fossil fuels. The final goal was to demonstrate that it is possible to capture 360 tones of CO2 per year and per hectare of microalgae, thus producing 200 tones of biomass, and extracting up to 2460 GJ of biofuel.

Moreover, this innovative technology would be demonstrated in two representative industries:
  • Glass production: characterised by flue gasses with moderate CO2 concentrations and high gas temperatures,
  • Lime production: characterized by flue gasses with CO2 concentrations and low temperatures.

CO2 is directly used by the algae in the photosynthesis process, and the heat contained in the gasses is used for thermal control of the culture and to power surrounding process, thus maximizing the environmental benefit of the pilots. Hence, demonstration on both production processes would show the versatility of the technology.

The final aim of this project was to demonstrate with 2 pilots on a scale of 1ha each the positive impact of biofuel production and CO2 capture with algae culture. Pilots will be feeding by fume from glass furnace or lime kiln.
