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.
