The East Yorkshire company, which is a contract manufacturer and packager to the agriculture and horticulture industries, will now be able to use the Soil Association mark and promote its organic credentials.
The Goole based company was given the rubber stamp by the Soil Association after proving it had robust systems and processes in place to track and maintain its, purchasing, storage, production, packaging and staff training procedures to ensure they are organic and sustainable.
The company which also manufactures and packages for non food sectors including auto, household and industrial chemicals, applied for the standard as part of its growth strategy to develop existing markets and increase its customer base.
Grotech Production has also recently started supplying a range of garden fertilisers for a high street discounter.
Customer relationship manager Stephen Moore said: "Grotech Production Ltd was keen to achieve Soil Association accreditation as part of our commitment to organic production and to add value to existing and new customers in the agriculture and horticulture sectors.
"By demonstrating that we have Soil Association approved systems and processes in place we can prove that our manufacturing is free from the risk of cross contamination, which could be a major worry for them.
"The Soil Association conducted a very thorough inspection of all our controls, cleaning and storage and we had to have very robust processes for batch documentation.
"Companies who currently have a Soil Association accredited product and need a manufacturer will now be able to commission Grotech Production Ltd with confidence."
Managing Director Martin Usher said: "I am delighted that we are the first contract manufacturer in the agricultural and horticultural sectors to achieve this prestigious certification. We have robust protocols in place to ensure that organic approved materials are dealt with correctly to avoid any risk of cross contamination. Also, being the first is very special".
