Using coffee grounds for clean, green spaces

Australia produces 75,000 tonnes of ground coffee waste per year. One company has used them in greenwalls and greenroofs, with refreshing results.

The Greenwall Company recently tested the effects of using spent coffee grounds in its greenwalls and greenroofs.

“Over the past six months,” founder Mark Paul recalls, “we have sourced coffee ground waste from Harvest Store & Kitchen in Newport, our local coffee shop, and included it in our patented media formula. Our trials on various walls and in our gabions used for greenroofs are proving to be a more sustainable and cost-effective solution with the plant species continuing to flourish.”

The Greenwall Company makes up its greenwalls and greenroofs from 94 percent recyclable materials that would otherwise end up in landfill. Ground coffee is just one component of the soilless, inorganic ‘media’ created by Paul to mimic the natural growing conditions of plants. The benefits of going soilless include a reduction in the overall weight of the wall or gabion, along with eliminating the need to replace the soil on a regular basis.

Greenwalls and greenroofs in your facility can have the benefit of improved air quality, noise level reduction, energy cost reduction and health benefits.

“Our aim has always been to reduce our carbon footprint by using everyday recyclable items. By diverting coffee waste from landfill, we are helping to reduce greenhouse gases gong into our atmosphere while creating a sustainable habitat for small animals and insects and also protecting the lifespan of our plants,” says Paul.
