DIVE LEAD-FREE,
A NEW RANGE OF LEAD-FREE WEIGHTS
FOR RECREATIONAL DIVING
 Sublest Company

Our small company located in West of France has sustainable development approach. Because we are very committed to sustainable development, we implemented series of solutions to reach our objectives. Indeed, we are changing completely our production of lead weights in aid of substitutes like coated cast iron. We did our best to make sustainable and good quality products. Two years of development and investment were necessary to end at the expected result.

The process of production of these new diving and spear fishing weights does not have negative impact for the environment. We replaced lead metal by cast iron (combination of iron and carbon), which has a negligible impact on the environment. Then, we chose to eliminate PVC for plastic material used for this production.

The plastic does contain neither toxic plasticizer nor bad metal. Besides, this plastic does not need strong demand of energy during its manipulation.

Moreover, quality of our products aims to extend their lives, which leads to raw materials consumption reduction like energy. In case of shock and break of the plastic watertightness, in order not to create any deterioration of cast iron, we added an anti-corrosive treatment.

RECYCLING

From conception, we anticipated every recycling constraint of our products. In order to easily separate plastic from cast iron when the weight is unusable (for divers who respect the environment), we decided to cover it with a plastic coat which does not stick to cast iron. Both materials must not be in the same recycling circuit in order to avoid burning of the plastic during cast iron melting. Then plastic will be thrown in non-recycling waste.
