Setting the tone for the conference, he called on national newspapers and broadcasters to reflect the hard work of local authorities to boost recycling rates.
He said: "There is a sustained campaign against what we [recycling officers] are trying to achieve. It is not a job shop. We are not bin boffins or waste rotweillers.
"I would like to offer a challenge to the national media. Use your position to engage the public and educate them on sensitive waste issues."
But he called on local authorities to help themselves by offering waste collection services that give as good a service as possible to the public.
He added: "The people we need to work most closely with are households. But I believe we need to offer a good basic service. We need to provide quality services and in that way counter the negative messages in the national media."
However, Marshall insisted that the Government should support local authorities and their recycling officers more.
"We need clear support from the Government and for it to say that alternate week collections are a reasonable way of collecting waste and bin chips are there to aid the process."
The LARAC conference is taking place today and tomorrow at the Bournemouth International Centre.
