The plastic containers are recycled in New Zealand, he says.
"It's made into underground cable cover that is used in trenches to protect power lines. The silage plastic is exported offshore because there are no processing facilities for it in this country."
Federated Farmers Bay of Plenty provisional president, Rick Powdrell, says there has definitely been an upsurge in farmers recycling.
"I can only go on my own personal observations but when you get around properties you see more and more farmers with recycling bags for silage bags and so on."
Recycling depots have also made a difference, he says. "There is a depot at Te Puke and when they opened I had a tidy-up and dropped off 144 containers.
"I suppose I had been storing them in anticipation it was going to happen. I think it's just the fact that the service is available and if it is relatively handy people will use it."
In the past, many containers would have been buried, burned or used for other purposes before being thrown in the rubbish, he says.
Agrecovery Foundation chairman Graeme Peters says there has been a 30 per cent jump in the number of people using Agrecovery.
"What is particularly pleasing is the increase in participation from sheep, beef and dairy farmers who have historically had lower participation rates than horticulturists."
Agrecovery also collect chemicals, but that campaign is not scheduled for in the Bay of Plenty until August next year.
