While delivering oyster mushrooms to restaurants in the heart of Montreal, Lysiane Roy Maheu stops to get a bucket filled with coffee grounds from a barista friend. She needs it for her next crop.

Mixed with residues from local micro-breweries, the grounds will provide rich nutrients for cultivating the sumptuous fungi.

They are grown in pierced plastic buckets stacked two metres high in a warehouse located in a former working-class, but now quickly gentrifying, Montreal neighbourhood.

Three times a week, Roy Maheu and her friend Dominique Lynch-Gauthier, both 35, harvest about 200 kilograms of mushrooms, which are delivered to area restaurants the same day.

This is the so-called circular economy — one that looks to boost productivity by recycling and recovering resources, all while reducing waste and avoiding pollution — at work.

By cultivating mushrooms from recycled resources, “we’ve eliminated waste,” explains Lynch-Gauthier, co-founder of the urban farm specialising in high-quality oyster mushrooms, Blanc de Gris.

“Waste is simply a resource that has been put in the wrong place,” she says, citing a founding principle of circular economies.

The pair started the company three years ago, and they sing the praises of recycling as a way to significantly reduce costs, as well as being environmentally sustainable.

To make their product, a mushroom culture is mixed with the coffee grounds and brewery dregs recovered from neighbourhood watering holes in buckets, rather than in disposable plastic bags used by most other mushroom houses.

There is no delivery waste either. Plastic bins used to deliver the mushrooms are returned to the vendor and used over and over.

“Any residue from the crop could be used as compost in vegetable gardens,” notes Lynch-Gauthier.

Roy Maheu has long worked in the restaurant industry and knows how important it is to personally approach chefs at Montreal’s best restaurants, to put the mushrooms in front of them to examine and taste.

“We aim to partner with high-end restaurants that share our values,” she told AFP.

One kilo of mushrooms is sold to restaurant owners for 25 Canadian dollars, including delivery. Walk-in orders are also sometimes accepted, for 15 Canadian dollars per half-kilo.

Despite these arguably steep prices, business is booming.

“More and more people are willing to pay a little more for local food” that is associated with ecology or organic farming, explained Rene Audet, a sociologist at the University of Quebec in Montreal.

As soon as the mushrooms are harvested, they are delivered to the four corners of the city, to retain their freshness and flavour.

“They are more beautiful, fresher and firmer,” said Julien Hebert Bouchard, chef at Les Fillettes restaurant, which put Blanc de Gris mushrooms on the menu in mid-2016.

Roy Maheu and Lynch-Gauthier have invested “hundreds of thousands of dollars” in their company, including monies from friends and family.

Despite their success at creating demand for their product, the company itself is struggling to reach profitability.

“We haven’t been paid in two years,” laments Roy Maheu, who was at one time juggling a night-time waitressing gig in order to get by. Still she and her business partner are undeterred.

Balancing demands on her time sometimes means picking up her eight-year-old daughter after school and bringing her along for deliveries.

“I take her on my restaurant tour,” she says with a smile.

In the future, the pair of entrepreneurs may diversify and add more types of mushrooms to their repertoire.

But for now, they are focused on a single variety as they seek to improve production and ensure that their customers remain happy.

The year they launched their mushroom business, Montreal saw the opening of its first rooftop greenhouses in a warehouse district of the city, selling local organic produce.

Although these greenhouses charge nearly double for fruits and vegetables compared to those shipped to grocery stores from abroad, demand for local produce is growing, fuelled by eating trends such as the 100-mile diet, in which everything you eat must come from within a 100-mile radius.

“I think there is a real motivation to transform our food system today,” said Audet, predicting that clusters of new artisanal producers will eventually reach a critical mass.

Initiatives that support “an alternative food system are rolling out more and more, are being recognised and are succeeding,” he said
