Biofertilizer from biowaste
Problem
The recovery of biological waste is an attractive approach within the framework of waste management policies and the development of a circular economy.
Organic waste from different sources is being underutilised as a potential resource of valuable compounds.
Solution
Thanks to IKERA RD8 technology, the production of fertilisers and biochar is possible from a variety of organic waste such pig purine, chicken manure, fish remains, animal blood, and used coffee grounds, among many others.
Process
Thermal energy is the main source of renewable energy used which can come from CSP, MINI-CSP, FVT, residual heat, geothermal and local biomass or a combination of several. The process can also can be achieved by using a mix of renewable and non-renewable energies.
The organic waste first goes into a tank from which we ensure the homogenisation of the waste.
It then continues through the IKERA RD8 physical reactor, in which we evaporate and condensate up to 99.8% of the water.
Leaving the solid part free of pathogens which can then be reused as a fertiliser base, fertiliser or biochar depending on the characterisation of the final product.
VOCS can also be recovered in a third stream and reintroduced according to needs.
The recovered water is pure and free of pathogens and solids having almost the same quality as distilled water.
Situation
We have successfully carried out viability studies into pig slurry and purine, chicken manure, animal blood, fish remains, used coffee grounds, among many others.
Thanks to the low level of humidity we have also achieved the removal of many heavy metals originally present in the wastes.
