Irish Standard 441:2011 National Standard for Compost Quality Published

I.S. 441 specifies quality requirements for compost produced from source segregated, separately collected, biodegradable materials including biodegradable municipal waste.

An Overview

During 2009, NSAI received a request from the Market Development Group (DOE 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.
