Fort Dodge city workers found lots of fully loaded recycling containers when they made the initial run of a trial collection system Friday, according to Public Works Director Greg Koch.
They also observed that the number of people participating in curbside recycling in the northern neighborhood where the collection was done more than doubled, he added.
''To see that drastic of a jump, I think, is very encouraging,'' Koch said.
He attributed the increase in participation to the ease of the new single stream recycling method now being tested in two areas. People taking part in the test don't have to sort out their recycling materials as Fort Dodge residents have done for years.
They merely put all the materials together into a large container, called a toter, provided by the city.
Single stream recycling is being tested for six months in 100 homes on the city's north side and another 100 on the south side.
Friday's collection was the first one for the homes on the north side.
In the past, an average of 30 of those 100 households participated in curbside recycling, according to Koch.
He said on Friday 76 of those households participated.
He added that most of the containers were filled to the top. About 30 cubic yards of material was collected.
That material was taken to the regional recycling center on Gypsum Hollow Road. Crews from Greenstar, a materials recovery facility in Des Moines, will pick it up there.
The initial collection from the 100 households on the city's south side will be on Wednesday. Future collections on the north side will also be on Wednesdays.
The entire city will be converted to single stream recycling, perhaps in 2014.
