A process to produce and valorise new aggregates from demolition materials

Gallery SAVE SAND 1


So far, quarry waste rock, as well as construction and demolition waste are mostly considered as Waste. However, spoils have a major asset: the sand. This natural resource, contained in concrete, is becoming increasingly depleted and scarce. But we still need it for new construction! Generated waste can become a valuable asset! There are indeed solutions for recycling. Our customers can make the most of their recycling and create a new source of income. Save Sand is a new generation of complete treatment plants, for the highest valorisation of recycled materials (quarry waste rock, as well as construction and demolition waste). It also represents a single, global offer covering the entire valorisation process of the products to be recycled! Our installations, therefore, make it possible to produce aggregates from demolition materials!

Implementation Stories

SAVE SAND by MS, le sable, l'eau, pour mieux construire demain.
Implemented by Vaills in Baho (France) in 2022

In 2022, the VAILLS company has decided to add a recycled materials recovery plant at its site in BAHO (66). This is a hydraulic sorting plant able to extract the aggregates contained in building and civil engineering rubble. In 2023, this plant is now able to produce recycled materials from various demolition and earthmoving sites, to recycle washing water and to dehydrate the sludge resulting from settling process.


Input rate: 150t/h of 0/4 sand, production target: 100 t/h of recomposed sand 0/1, 1/2 and 2/4


The environmental benefits

  • The various aggregate fractions are fully reusable and can be used in all types of applications, including the production of high value-added concrete sand - Our plant recycles about 100T/h of sand every day
  • Clarify the wastewater from the washing of materials, to be able to supply all the equipment involved in the process (washing trommel, screens, washers, dewaterers) with quality, recycled water = 85% water saved
  • Keeping water losses in the sludge to a minimum and therefore reduce the need for an external top-up - Additionnal filter presses increase the rate of water savings to 95%
  • Reduced use of non-renewable resources : The proportion of recycled aggregates is estimated only 10% of total national production - Our solution, installed as widely as possible, could increase this figure to 30-40%
  • Reduced carbon impact on the environment. All MS installations are remanufactured and rebuilt using recycled materials from ephemeral installations

The Financial benefits

  • Resale of sand and associated income, choosing your granulometry. Sold at the same price, recycled sand has met the challenge of being environmentally friendly without being more expensive
  • Reduction of sludge transport costs : Dewatering the residual sludge enables it to be transported. It is then transported and sold, to be used in most cases as backfill
  • Reuse of washwater : Based on the principle of a wastewater treatment plant, the water treatment unit designed by MS integrates the functions needed to treat and then recycle water, saving up to savings of up to 98%!
