A method and a device for preparing graphene and hydrogen gas by converting waste plastics with Joule heat are provided according to the present application. The method uses the Joule heat generated when a strong current passes through the mixed plastic material mixed with conductive additive, as the reaction driving energy. By Joule heating, carbon-carbon bonds and carbon-hydrogen bonds are broken, amorphous carbon is converted into sp.sup.2 hybridized high-purity graphene, and hydrogen atoms are converted into hydrogen gas. The reaction device used by the method is mainly composed of three parts: an airtight reaction chamber, a gas collecting system and a power control system.

Lead is recovered from lead paste of a lead acid battery in a continuous and electrochemical lead recovery process. In especially preferred aspects, lead paste is processed to remove residual sulfates, and the so treated lead paste is subjected to a thermal treatment step that removes residual moisture and reduces lead dioxide to lead oxide. Advantageously, such pretreatment will avoid lead dioxide accumulation and electrolyte dilution.
