Description

CLIC RECYCLE implemented an innovative mulch solution derived from recycled hair in agricultural settings, specifically for lettuce and cauliflower crops. The field trials were conducted at the Centro Experimental Cajamar Paiporta (Valencia) in collaboration with the Universidad de Almería. The trials tested Clic Recycle’s mulches against conventional plastic mulch alternatives, including low-density polyethylene (LDPE) mulch, polylactide (PLA)-based mulch, and starch-based mulch. The results demonstrated that CLIC RECYCLE mulch significantly reduced environmental impact, including lower CO2 emissions and improved soil water retention.

Impact & Result

CLIC RECYCLE’s mulch significantly reduces GHG emissions, with 73% of LDPE’s CO₂eq for cauliflower and 55% for lettuce, saving 519.6 kg CO₂eq/ha for lettuce and 504.45 kg CO₂eq/ha for cauliflower. It prevents 928.8 kg of LDPE waste per hectare over six years, avoiding microplastic pollution. Additionally, it reduces irrigation water use by 30.35%, cutting fossil fuel dependency and promoting sustainable, climate-resilient agriculture.

Solution Spotlight

Soil is essential for food production, biodiversity, and climate resilience, yet 60-70% of EU soils are unhealthy, with over a billion tonnes lost annually due to erosion. The degradation, driven by pollution and unsustainable practices, costs over €50 billion per year. CLIC TERRA, a biodegradable mulch made from recycled human hair and natural fibers, replaces plastic and peat-based mulches. It enhances soil health, retains moisture and nutrients, and prevents chemical and plastic pollution. CLIC TERRA Smart Biodegradable Mulch integrates IoT sensors, optimizing water use and improving crop resilience. By providing a bio-based, circular alternative, CLIC TERRA eliminates plastic waste, reduces environmental harm and enhances biodiversity and circularity. It promotes regenerative cultivation by offering a sustainable alternative to mainstream, resource-intensive products.
