Rationale 2.11

Waste is generated through human activities such as agriculture, construction and demolition, industrial or commercial operations, the healthcare sector and domestic refuse. Improper material use and disposal can cause long-term pollution of terrestrial and aquatic environments, and have a direct effect on biodiversity loss, pollution and climate change.5353UN Environment Programme (2024).

From construction, to operation and decommissioning, aquaculture farms use materials and generate waste that can be hazardous. Copper-based antifoulants can leach into the water and cause harm to marine life in the water column and to the sediments below the farm. Therapeutants and chemicals used to treat farmed animals can also create unintended impacts on the animals themselves, the ecosystem and their handling staff.

Aquaculture gear or infrastructure can contribute to plastic pollution in aquatic environments, particularly where materials are lost, damaged or degraded. Plastic pollution can persist in the environment, affect habitats and wildlife, and create long-term risks for aquatic ecosystems. Responsible material use and management practices can reduce the likelihood of plastic loss, leakage and pollution from aquaculture operations.

This Criterion focuses on ASC-certified farms using, and re-using, resources responsibly, minimising generated waste, and preventing pollution and harm to communities and the environment.

Intent – The aquaculture industry prevents pollution by responsibly managing and disposing of waste and chemicals.
