heavy metals
Heavy Metals are present in many forms of domestic and industrial waste. Heavy Metals include copper, Zinc, Cobalt, Lead, Mercury, Chromium, Cadmium. If Heavy Metals remain in wastes that are incinerated or land-filled, there remains a potential for environmental pollution from the ashes generated or from leaching of the metals.

Hydrometallurgy
Hydrometallurgy is concerned with the process of extraction of metals by dissolving them into and acidic or alkaline solution and by sedimenting metal salts from solution. Pure metals can be produced by the electrolysis of the metallic salts.

Industrial waste
Industrial Wastes are those wastes generated by industry, businesses and transportation.

Used batteries
Used batteries can be primary batteries (non-rechargeable) in which some of the stored energy has been used or secondary batteries (rechargeable) which have experienced a number of charging cycles.

Alkaline battery
Primary (non-rechargeable) cell or battery based on Zinc, Carbon and Manganese compounds with an alkaline electrolyte. Recupyl has developed a patented process for the treatment of Alkaline Batteries.

Zinc carbon battery
Primary (non-rechargeable) cell or battery with zinc and carbon electrodes and a acidic salt electrolyte. Recupyl has developed a patented process for the treatment of Zinc Carbon Batteries.

Lithium ion battery
Secondary batteries with an anode containing lithium and an electrolyte based on an organic solvent. Recupyl has a patented process for the recycling of Lithium Ion batteries which has been in industrial operation since 2007.

Lithium polymer battery
Secondary batteries with an anode containing lithium and an electrolyte based on a solid polymer composite. Recupyl has a patented process for the recycling of Lithium batteries which includes the evolution of the Lithium battery technology, including Lithium Polymer batteries.

Recycling of batteries for electric and hybrid cars
Electric and Hybrid cars will become increasingly popular and will comprise an increasing proportion of the total volume of cars on the roads. Due to the significant size of the batteries for these vehicles (measured in 100s of kg), there will be a significant recycling challenge for these batteries at their end of life. Recupyl has patented processes for the treatment of batteries used in electric and hybrid cars.

Industrial sludge
Industrial sludge typically contains traces of heavy metals which are hazardous wastes. Recupyl has patented processes to extract heavy metals from Industrial sludge, thus rendering the sludge non-hazardous as well as valorising the metals.
