  1. Small scale tests casts will be made in Finland and Poland to measure the emissions of the casting processes. The measurements will made for ferrous castings using both organic and inorganic binder moulds. Chamber test methods and tests in laboratory foundry will be applied.

  2. Total emissions of five pilot foundries in Europe will be measured and compared representing both organic and inorganic binder system sand moulding systems.

  3. Indoor air quality will be measured and compared in same pilot foundries.

  4. Full production scale test series with inorganic binder system moulds and cores will be made in two ferrous foundries. Inorganic binder suppliers will be contacted in early stage of the project to receive the newest information about the state-of-art and to choose the best inorganic binder options for the tests. Karhula Foundry in Finland is demonstrating stainless steel castings using different inorganic binders and sand types. Binder-sand combinations based on the recommendations from the binder suppliers will be pretested using test sample moulds. FOM Tacconi in Italy is demonstrating alloyed iron casting using different inorganic binder cores and moulds. The properties of the cores and moulds as well as the quality of the castings will be widely tested.

  5. Foundry sand recycling options will be tested and compared for inorganic and organic binder sands. Thermal reclamation and ultrasonic + hydromechanical methods will be tested for using recycled sand in coremaking.

  6. Purification methods for surplus foundry will be demonstrated. Waste sands from organic and inorganic binder systems will be tested using composting and washing methods. The goal is to find ways to reuse surplus foundry sand e.g. in geo-construction or soil mixture instead of land filling. The cleaning of surplus foundry sand by composting method was developed and tested with organic binder system sand in previous LIFE project called “Foundry Sand” (LIFE13 ENV/FI/000285) in 2014-2018, coordinated by Meehanite Technology. The test results were encouraging and Meehanite Technology has the patent for composting method.
