Seaweed: An Efficient Metal Cleaner

In a project dubbed "Seasurf", an Italian company, Natural Technologies, has developed an innovative metal degreaser using sustainably harvested kelp seaweed. The seaweed provides natural surfactants. Two formulations were developed, each having significant health, safety and environmental benefits over existing solvent and aqueous-based products. Both formulations are effective at ambient temperature (30°C) which gives them an edge over aqueous cleaners. :: Via Pera
