People living close to the site have said there are still "regular problems" with smells coming from it, but the company insists it is working with residents to tackle any problems.
A TEG spokesman said: "The site is a former agricultural building and has open slats around it which we cannot seal up due to planning restrictions.
"We have had these odour sprays at the entrance and exits of the building for many years and now we are looking at increasing these to the rest of the building.
"We are very keen to be good neighbours and are trying to be innovative about the problem as we look to bring odours down to a minimum."
She added that the company had met with people living on Ratten Lane in recent weeks to discuss any issues they had with the facility.
A spokesman for the Environment Agency confirmed its officials had met with TEG to talk about how it could create the "odour curtain" around its facility.
But, she confirmed that no enforcement orders had been served on the company in relation to the smells.
Bill Whittle, the clerk of Hutton Parish Council, said it regularly received complaints about odours coming from the former cattle barns.
He said: "We do support residents' concerns but we are not the authority responsible for it, so always advise people to speak with the Environment Agency."
People living on Ratten Lane waged a long-running battle in a bid to stop TEG converting the former farm buildings in 1997 and then campaigned against plans to widen the range of waste it composts.
