Spray-applied surface stabilisation delivers immediate particle binding and erosion protection on exposed mineral substrates. Biopolymer Solutions GmbH develops mineral-fibre based alternatives that are biodegradable, free of synthetic film-forming agents, and designed for regulatory conditions progressively restricting synthetic polymer use.
Conventional spray-applied surface stabilisers use synthetic film-forming binders — typically styrene-acrylate copolymers. These are effective but carry microplastics liability and face EU REACH restrictions. Lignin-based dispersions are an improvement but are imported liquids with supply chain constraints.
BPS develops mineral-fibre systems using recycled industrial fibres, mineral fractions, and natural binders. Applied hydraulically through standard hydroseeding equipment. Fully biodegradable, no synthetic residues, compatible with subsequent vegetation establishment.
Two functional variants: surface crust system (dust suppression, slope fixation on non-trafficked surfaces) and structural surface consolidation (trafficked surfaces, construction access roads requiring load-bearing capacity).
BPS uses recycled construction industry material streams as the carrier matrix base — converting waste streams into functional engineering materials. Systems are applicable through standard hydroseeding equipment and can be reapplied after degradation without synthetic residue accumulation.
Synthetic film-forming binders will face progressively tighter approval conditions. Mineral-fibre systems are positioned for the regulatory environment that is replacing synthetic polymer use in soil contact applications.
Surface stabilisation system selection depends on substrate type, exposure conditions, traffic loading, and regulatory context. SRBT and Biopolymer Solutions GmbH specify the system as part of the overall site protection concept.
