Development of a Mobile Recycling Kit (MRK)

In this subtask two kits will be developed:

  • Clearing kit (CK): to clear and collect debris construction material after a disaster.
  • Debris recuperation kit (DRK): this kit will be optimized for the use of the crushed material resulted from the breaking of demolition debris.

By combining these two kits, the aim it to be able to reuse 100% the debris, so that nothing is lost, and the demolished material becomes part of the new infrastructure. Requirements for the two kits are based on pre-studies and the guide lines are the following:

  • Output of the Clearing Kit should be at least 20 tons/day of crushed concrete,
  • The DRK should be able to deal with around 10 ton/day, the rest of the output; can be used as road base material or other alternate applications, or stored for further use.
  • The production line should be as simple as possible , in terms of operability, maintenance and construction
  • The components of the kits will be based on existing commercial available products as much as possible.
  • The end product should be widely applicable, meeting needs of different of disaster areas
  • The product should be substantially constructed with locally available raw materials
  • The product will be optimized for the reuse of the crushed debris
  • The CK and MRK should be able to be operated by local work force as much as possible.
  • The MRK kits have an electric drive, to create simplicity in the energy and to keep maintenance to a minimum even though this requires providing a sufficiently large energy source.
  • The other requirements set up by WP1 will be leading for the solutions sought, especially in relation to the standard requirements for transportation.

Additionally, the newly developed components of the kits need to be optimized and tested, preferably by building a test set up, using real concrete debris. Sorting and sieving has to be tested to optimize the use of crushed materials, and of course the production of materials such as concrete blocks and prefab elements has to be tested as well. (this will happen under WP6)

The actual production of concrete is divided into two broad types of modules:

  • The preparatory modules: these are the ingredients together and dosed into the mixer for concrete
  • The manufacturing modules: developing formworks or molds to pour the concrete or press it into bricks. Obtained building materials will be tested for mechanic properties.

Each equipment piece will be provided with a manual for the operation, giving detailed instructions, to ensure the simple and efficient use of the kits.
