The policy draft describes plans for the development of infrastructure in the Agri-Park including sewerage, power supply and an In-Vessel composting treatment facility for food and biomass recycling. This is not explained in much detail. If the new policy wants to establish synergies and optimize ecological performance at the heart of the Agro-Park (its utilities), then I suggest to consider the production of clean, high-temperature charcoal dust (biochar). The durability and super-porous microstructure make biochar a long-term storage medium for the soil's microbe life, plant nutrients and moisture. Soils amended with biochar have proven to be very resilient to weather extremes and nutrients fluctuation. The extraordinary vitality of biochar-enhanced soils provides outstanding fertility and climate change mitigation.
