RegulationsQuickly developing and changing
Confusing, uncertain and sometimes conflicting
Laws related to using ash and ash production:Law on Environmental protection ja –decrees, National law of waste, waste
directive and End of Waste-criterias, Decision dumping sites, Waste taxation, Sideproducts, Direction on using ash (as waste) to soil construction, Safety
Products are regulated by:Law of fertilizers and directions,
- different products to silvi- and agriculture- REACH, (Mixed ashes)- CE-, - Law on radiation
Recommendations for sideproducts (Trafic administratives, Concrete industry, Asphalt industry)
Forward and upward…
-> Regulations has affected recently positively -> General opinion favours
Aim From waste to product
