Scientific novelty
A biomat for the reclamation of disturbed lands has been proposed, consisting of a structure with at least two layers: one layer containing seeds, and at least one other layer containing Na-carboxymethyl cellulose, last year's leaf compost, and paper/cardboard waste, with the following component ratio (wt. %): last year's leaf and needle compost 49-50; paper and cardboard waste 50.6-49.5; and Na-carboxymethyl cellulose for the remainder.
Advantages
Studies conducted to identify the most effective composition of a biomat made from Hazard Class 5 biodegradable waste—by determining the percentage of seed germination and the rate of biomat structure degradation—demonstrated that a biomat made from a mixture of plant waste (specifically leaf and needle compost) and paper and cardboard waste from office activities showed high efficiency in soil sodding. The proposed biomat is environmentally friendly and biodegradable compared to known analogues, as it contains no synthetic additives.
Commercial implementation
The primary regions for implementation are anywhere the following waste and components are generated: - paper and cardboard waste from office activities (GOST 18510-87, FKKO code 4 05 122 02 60 5 – Hazard Class 5); - last year's leaf and needle compost (FKKO code 7 31 300 02 20 5 – Hazard Class 5); - Na-carboxymethyl cellulose (produced in accordance with TU 2231-034-07507908). Paper and cardboard waste from office activities belongs to Hazard Class 5 (FKKO code 4 05 122 02 60 5), offering advantages such as universal availability and the absence of negative environmental impact.
