Scope of standard
I.S. 441 specifies quality requirements for compost produced from source segregated, separately collected, biodegradable materials including biodegradable municipal waste.
During 2009, NSAI received a request from the rx3, formerly the Market Development Programme implementation Team (a Department of the Environment. Community & Local Government initiative) to develop a national standard for compost quality to enable compost producers market and sell their products throughout Europe.
The development of a national compost quality standard is seen as necessary to help create and stimulate markets for compost-based products and will contribute to the reduction of biodegradable wastes going to landfill. Additionally, such a standard is seen as supporting the long-term growth of the industry and ensuring product satisfaction to maintain consumer confidence.
