A new type of compost made from human excrement is available for residents of Moncton, N.B., for use in their gardens.

The compost, being offered free for the time being, is made from human waste recovered from the city's sewage plant.

The plant is able to extract about 10,000 tonnes of human solid waste annually, said Ron LeBlanc, president of the Greater Moncton Sewage Commission.

The current batch of compost took about two years to process, LeBlanc said.

The solid waste has lime added to it and is combined with bark, hay and wood chips. The substance is then heated to 75 C to kill bacteria, LeBlanc said.

LeBlanc said the city recognizes people may have concerns about the compost, but it is safe to use and also a high-quality compost product.

"The thing you've got to remember is what went into your waste at the end of the day is what you felt was safe enough to eat," he said.

The city's sewage commission will host an open house on the weekend to showcase its composting facility and the product, which is being marketed under the name Gardener's Gold and will be offered for sale down the road.
