Blue Roof – A Roof Made From Sewage Products

November 21st, 2017
BlueCity Dome, Rotterdam

BlueCity Dome

In Rotterdam, BlueCity is a Circular Economy incubator for companies developing technologies that create products from waste. So far they have about 12 companies that are working within their facilities – which are located in a defunct indoor tropical swimming centre called Tropicana. Instead of tearing down the building, this group has gone in to give it a second life. In terms of the kinds of businesses they have been incubating, here is how they explain it:

The entrepreneurs located in BlueCity all connect their waste-streams in different ways.  The coffee-waste that is produced by Aloha Bar-Restaurant serves as nutritious soil for the mushrooms of RotterZwam. The carbon dioxide that is released in the process is used by Spireaux for the creation of Spirulina, and in BlueCity Lab mycelium is used to develop packaging materials. Of course, to complete this perfect circle, you will ultimately find the mushrooms that grew on the coffee waste of Aloha on the menu of the same restaurant. [source]

They recently launched the BlueCity Circular Challenge in which they challenged multi-disciplinary teams of students and young professionals to come up with solutions to some chronic waste problems. Four companies offered up their waste streams to see if the teams could come up with a marketable product from the waste.  The waste streams were:

  • disposable coffee cups,
  • the filtered-out waste from sewage treatment plants (ie., sanitary products and flushable wipes, etc… – stuff that isn’t even supposed to go into the sewage system but ends up there anyway),
  • electric meters made out of Bakelite,
  • the horticultural business left if up to the team to decide which waste stream to address.

The winner was the team that took the filtered-out waste and turned it into a substrate for green roofs. It turns out that all those products (sanitary napkins, tampons, wipes…) are also highly absorbent, meaning they can soak up a lot of liquid. That makes them a great starting product for a green roof base because they can hold enough water to help get the plants going and can absorb rain really well while diverting rain from the sewer system. The idea is to sterilize, dry and compress the waste into tiles, and then use it in green roofs as a substrate. The team won €5,000 and a place at BlueCity to further explore their idea.

Urban Agriculture: New Project at le Palais des Congrès de Montréal

Harvest Bounty from the Montreal Convention Centre's Green Roof

Harvest Bounty from the Montreal Convention Centre’s Green Roof

Like many cities across North America, Montreal has problems with localized heat islands during the summer, raising the temperature significantly compared with its surroundings. This effect is due to the density of buildings and road network, and not enough green space to absorb the sun’s heat.  In addition, with changing and somewhat unpredictable weather conditions due to climate change, an increasing number of cities are beginning to experiment with different forms of urban agriculture. One of the projects in Montreal is a partnership between the Montreal convention centre (le Palais des Congrès de Montréal), the department of urban agricultural research from the university of Quebec at Montreal (AU/LAB at UQAM), Miel Montreal, and La Ligne Verte. This is a true collaborative project to learn what is possible regarding growing food within the confines of a rooftop. The project aims to fulfill several objectives:

  • Reduce heat island effect for the neighbouring area;
  • Absorb stormwater;
  • Produce plants and vegetables for a variety of uses;
  • Preserve heirloom seeds from some rarer varieties of plants;
  • Demonstrate Montreal’s efforts to become a resilient city in the face of changing weather patterns;
  • Provide a “lab” like setting to develop new vertical farming techniques.

Canmore Black Shake

Canmore Black Shake

Euroshield is a rubber roofing product that has been manufactured in Calgary, Alberta for the last 13 years.  It is made from 75% recycled rubber tires and 20% other recycled material for a total of 95% recycled material. Each new roof contains between 250 and 1000 rubber tires, and any scraps produced during installation can be collected and recycled into new product (depending on location).

There are four product lines:

  • EuroSlate, mimics the look of slate. Available in Brownstone, Greystone and Blackstone colours.
  • EuroShake, mimics the look of cedar shakes — available in either the hand split or taper-sawn looks and three colours: weathered brown, grey and black.

Both the EuroSlate and EuroShake are the original products developed by EuroShield. They are about 3/4″ thick at the butt end and interlock using a tongue and groove system. They weigh approximately 3.3lbs/square foot and need no additional truss support.

Waterfront Toronto Aims to Build the Greenest Community in North America

Sherbourne Common at Night

Waterfront Toronto was established in 2001 by the city of Toronto, the province of Ontario and the federal government. Its mandate was not just to revitalize the waterfront area, but also to do it using a framework of sustainability. They have developed incorporated into the design such things as making the roadways more pedestrian and bike friendly, creating parks surrounding housing developments, creating mixed-use spaces for businesses, services, education and housing. Low-income housing was also included in the plan. The building code standards are stricter than the city’s and are continually improving. Finally, riverfront and lakefront rehabilitation was one of the primary mandates. If you haven’t been down to see the wave decks yet, they are unique, award winning structures that have provided connections and continuations of pathways, but have also assisted in revitalizing the lake beneath it. Toronto Conservation Authority counted an increase in fish species below the decks from six to 27 at last count. » Read more: Waterfront Toronto Aims to Build the Greenest Community in North America
