The event was held at David Kean's Farmers Dipping Co site, Limehills, on September 4 and was one of six pilots to be held throughout the country.
The other South Island sites were at Selwyn and Geraldine.
Farmers and growers dropped off chemical containers, silage and bale wrap, fertiliser and feed bags, waste oil and unwanted or unidentified chemicals for safe disposal and in some cases recycling.
Agrecovery rural waste one stop shop project manager Brian Vass was pleased with the success of the Limehills event.
''We had 50 people who came and processed over 1200kg of chemical containers,'' Mr Vass said.
As farmers dropped off the chemical containers, Agrecovery contractor Rodger Gregge, of Ashburton, put them on to a conveyor belt to be ''chomped'' by a machine on board the AgRecovery truck.
The shredded plastic 'bits' are then sent to Auckland and turned into plastic pellets, then could be sold overseas or turned into underground cable covers.
Mr Vass said there was a demand for the service with about 600 tonnes collected from Southland annually.
Plasback collected silage and baleage wrap, as well as polypropylene bags as part of the drop off shop.
Fulton Hogan's Rose (Recovering Oil Saves the Environment) truck collected waste oil for disposal at the same time.
Environment Southland also provided support for the day.
Site owner and contractor David Kean said the collection event encouraged farmers to get rid of both chemical containers and unidentified or unused chemicals.
''It is magic,'' he said.
''It has been a cracker day for the environment and it has given farmers the ultimate opportunity to tidy up the back of that shed they have been leaving for a rainy day.''
Mr Vass said the Government was calling for submissions on a consultation document, which discussed introducing more stringent or mandatory participation regulations, under the Waste Minimisation Act.
Submissions close on October 4.
