The company is the only growing media company to have achieved this, reaching full compliance to all the elements of the scheme.
BOPP growing media accreditation encompasses health and safety, the environment, quality, product safety and ethical standards.
Westland Horticulture joint managing director Edward Conroy said: "We strive to deliver quality products to our customers and the BOPP standard just shows how dedicated we are to this. As the only manufacturer to have the BOPP accreditation we know that our customers are selling product of the highest standard".
Westland has also achieved other accreditations recently including Forest Stewardship Council Certificate, Growing Manufacturers Association Baseline Audit, Growing Media Initiative, ISO 9001 & 14001 and Soil Association Producers licence.
