using installa- tions for separating and recycling bdkmaterials, the goalsaimed forwereachieved. In compa- rison with the status at the beginning of the & project, the following were achieved: - reduction of the burden of heavy metals, carbon and phosphorus on the process circuits by separating these pollutants from the electrolysis exhaust gas and from the waste from various filtering separators of auxiliary operations, thus - reducing the burden on the workplaces, - substantially improving the quality of the metal, - slightly improving the current efficiency, and - limiting the generation of waste to 5 kg/day. , Fig. 1 : Flow chart of secondary oxide disposal 2 3 Duration: 0 . 1.8 - 3.0.8 0VQ2 Subject: Development work on reutilisation of the waste plastic of secondary lead works based on battery scrap Research centre: Metall-Laboratorium der Metallgesellschaft GmbH Reuterweg 1,6 Frankfurt Government sponsorship: DM 8,2.0 Sponsorship ratio: 4% 1. Purpose of the project The underlying principle of the Braubach recycling concept for old batteries is the extensive reprocessin of the secondary materials, in order to put them either back to their original use (grid metal,%attery pastes) or to some other adequate use (sulphuric acid, sulphate sulphur) The polypropylene scrap is predominantly case of hi quality copolymers, whose recycling in demanding applications, such as engineering mouIc?ng compounds,appears to be sensible from the point of view of the national economy Hard rubber and chlorine-free plastics can be used as auxiliary fuels, insofar as they can be separated from the PVC Some of the technolo ies to be used for recycling waste plastics are onlyfamiliar on labora- toryor pilot scale, andaave not yet been adequately tested on an industrial scale, others have not yet been examined as combination of individual stages and, in the special case of reutili- sation of waste plastics from old batteries, not yet developed ~
