The primary aim of the work is to reduce the zinc content of rubber articles (currently in the EU about 100,000 tonnes of zinc in about 5M tonnes of rubber products per annum) by 50-100% through improved rubber compounding.
There is a need to reduce the zinc oxide used in rubber compounding because of increasing concern for the environment. As examples, zinc may be released to the environment in the effluent from latex processing plants, through wear of tyre treads, or during the disposal of rubber products. It had proposed that zinc oxide be classified as “very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment”. Zinc and zinc chemicals are also included in a priority list of rubber chemicals, compiled by the Swedish Environment Protection Board, that they propose should be replaced or used restrictively.
