By-products to enrich compost and biochar mix to biofertilisers
organic fertiliser and solid waste department at Agrienergia
About
our ideas is to produce biofertilisers, we need by-products or waste with possibility to extract NPKs or other to produce the following: the following: 1. quality.
2. Compost + Biochar + Nutrients (e.g. natural ammonium sulfate, struvite)
o Synergy between biochar and compost improves structure, water retention, and nutrient
availability.
o Biochar will be added at the beginning of the process to enhance biogas yield and compost
Compost enriched with Effective Microorganisms (EM)
o Compost matured with microbial inoculants, nettle extract, and rock powder.
o Later enriched with zeolite, basalt, activated biochar, and mycorrhizal fungi to reproduce peat-
like properties.3. Biostimulant + Biochar + Compost (peat substitute)
o Blends with physical and agronomic characteristics similar to peat, anticipating its possible ban
by 2030.
4. Biostimulants from agricultural residues
o Compost-based solid and liquid biostimulants, including compost tea.
