´EnviroMan´ Environmentally adapted metal manufacturing processes; chemical and waste material recyc
Purpose and goal
The project EnviroMan, Environmentally adapted metal manufacturing processes, is part of the FFI Strategic Vehicle Research and Innovation collaboration program Sustainable Production, handled by VINNOVA. The R&D work had a wide scope, covering innovative and sustainable process fluid cleaning methods, environmentally adapted heat treatment processes, minimized waste products from foundries, and a specific focus on methods for energy and environmental analyses. The R&D work has mainly reached the goals, and presented methods and techniques possible to adapt or use.
Results and expected effects
Innovative and sustainable cleaning of process fluids: Both ozon and UV-light gives effect, but needs optimized process control, system design and handling routines. Environmentally adapted heat treatment processes: It seems to be possible to extend the service-life of those washing/cleaning baths. The study according to polymer quenchants resulted in a guide, on how to handle quenchants in workshops. Material recycling of residuals from foundry processes: Will signigicantly contribute to reduce waste to landfill and increase internal reuse of sand and fine-grained particles
Approach and implementation
In each of the R&D-areas, specific methods and advanced instruments are used to evaluate the analyses performed. Four main methods are used for energy and environmental analyses: Life cycle analyses, LCA Energy mapping Chemical mapping System Dynamics Those methods are applied in the research work and in the case studies. LCA are e.g. made for alternative methods to clean process fluids, different pre-cleaning methods before heat treatment and for the handling of foundry sand. Combinations of the methods are also used to model and describe more complex relationships.
