Washing plants for road sweeping waste
and for the recovery of sand and gravel
During street cleaning operations carried out by municipal companies, sweepers daily collect large quantities of polluting waste that require specific treatment.
This process is essential to minimise the amount of material going to landfill and, at the same time, recover all waste fractions that can be valorised as useful resources.
From our streets a resource to be valorised
Our plants for the recovery of sand and gravel from street trash are designed and manufactured to guarantee high quality products.
The extremely reduced environmental impact produced by soil-washing meets compliance and safety standards for most authorities who are responsible for operating concessions.
The innovative technology of our plants, which has been extensively documented and tried and tested, allows for excellent economical operation.
The fully recyclable products obtained after the washing and sorting process, to be considered as a valuable alternative resource to reduce the need for new quarries and landfills, are as follows:
- 60-70% of sand, fine gravel and gravel certificates for building use
- 10-12% of organic fractions convertible into compost
- mixed waste
- iron metals
- dehydrated sludge
- coarse materials 20/10mm

Plant composition
The main sections that make up street sweeping systems are:
- solids treatment (mechanical plant)
- liquid treatment (chemical-physical plant)
- sludge treatment
Economic-environmental advantages
- drastic reduction of disposal costs
- recovery of washed materials such as fine gravel, gravel and sand, resalable materials
