Ecotoxicity Assessment of Biodegradation Residues
topic
Compost and soil ecotoxicity testing after textile biodegradation uses standardised plant seedling emergence and growth tests with radish, barley, and cress seeds in compost containing textile degradation residues at defined loading rates, measuring germination rate and biomass production relative to blank compost controls to detect phytotoxic degradation byproducts.
Role
Ensures that biodegradable textile materials do not release phytotoxic degradation intermediates during composting or soil burial that would compromise compost quality or agricultural soil productivity, a mandatory requirement of industrial compostability certification under EN 13432 and an important ecological safety assessment for biodegradable mulch textile approvals.
