The present disclosure relates generally to systems and methods for recycling lead-acid batteries, and more specifically, relates to purifying and recycling the lead content from lead-acid batteries. A system includes a reactor that receives and mixes a lead-beating material waste, a carboxylate source, and a recycled liquid component to form a leaching mixture yielding a lead carboxylate precipitate. The system also includes a phase separation device coupled to the reactor, wherein the phase separation device isolates the lead carboxylate precipitate from a liquid component of the leaching mixture. The system further includes a closed-loop liquid recycling system coupled to the phase separation device and to the reactor, wherein the closed-loop liquid recycling, system receives the liquid component isolated by the phase separation device and recycles a substantial portion of the received liquid component back to the reactor as the recycled liquid component.

The invention relates to a process for the production of a recyclable product () made from a first material, wherein before or during the production of the product () a first marking material is added to the first material and the product () is produced from the first material with the admixed marking material, wherein the first marking material can be automatically detected in a recycling plant in the first material of the product () after the production thereof. The invention also relates to a process for the recycling of a product (), wherein the product () is manufactured from a first material, to which a first marking material is added, wherein the product () or pieces () of the product () are separated from one another and/or from other objects in a recycling plant, in that the first marking material is detected in the first material of the product () or the pieces () of the product (), and the product () or the pieces () of the product () are separated from one another and/or other objects, in which no marking material or a different, second marking material is detected. The invention also relates to a recyclable product and a recycling plant.
