Working together is better

WRAP (Waste and Resource Action Plan) state their mission is to accelerate the move to a sustainable, resource-efficient economy through:

  • Re-inventing how we design, produce and sell products
  • Re-thinking how we use and consume products
  • Re-defining what is possible through re-use and recycling

At BlockWalls we too want to support the circular economy. We manufacture interlocking concrete blocks using recycled materials and other waste streams which supports the circular economy and significantly reduces Co2 emissions.

Concrete is the second largest commodity in the world, second only to water and it produces over 7% of the worlds man made Co2 emissions, the main culprit being the manufacture of cement.

The first question is – What waste streams and material can we use to manufacture concrete?

Conventional concrete is made from aggregates and a binder which holds it together.

In place of quarried aggregates and commercially produced cement we can use a number of recycled aggregates and novel low carbon cement types, for example:

Aggregates

  • Crushed concrete and brick rubble demolition – This material can be crushed down to 40 and 20mm aggregate.
  • Recycled glass from recycling plants – we have process that breaks the glass down into 10mm aggregate and fine glass sands.
  • Washed road sweepings.
  • Residues from thermal processes such as bottom ash or slags

Cement Binders

  • Incinerated paper pulp sludge
  • Air pollution control residues
  • Incinerated sewage sludge ash
  • Alumina
  • Alternative alkali binders
  • Pulverised Fuel Ash

We are working closely with university material scientists and waste industry partners to develop concretes that are:

  • Stronger
  • More heat resistant
  • More chemical resistant
