Periodic Reporting for period 2 - NUOVOpb (A unique Lead Acid Battery (LAB) recycling technology to reduce CO2 emissions by 89%, reduce waste by 81%, and transform the battery recycling industry)
Reporting period: 2018-05-01 to 2019-01-31
The global LAB market is expected to grow by 59% (2014-22) to €71.6 billion by 2022, with the demand for waste management of toxic battery waste also increasing. This growth will inevitably place great demand for more energy-efficient, eco-friendly recycling methods.
To address this, Aurelius Environmental will commercialise NUOVOpb. NUOVOpb is a low energy, clean, low-cost, scalable method of recycling LABs, based on a unique hydrometallurgical process that transforms spent battery paste into a superior form of battery-ready product reducing the environmental impact of the paste recycling process, consuming far less energy than current recycling technologies. T
The scalability and low-cost of NUOVOpb make it ideally suitable for localised implementation, avoiding hazardous waste transportation. The process will lead to production of superior battery paste, which in addition to the environmental impact can also produce recycled batteries which can potentially outperform batteries made from virgin lead metal.
Our product will be high-quality LAB-ready lead oxide for battery manufacturing and will meet EC priorities by addressing resource efficiency, sustainable supply of raw materials and by driving the circular economy.
During the 2nd Reporting Period, AEL have refined and improved upon the NUOVOpb process to the point that we have successfully manufactured highly refined leady oxides from our process. In addition, the parameters for the successful monitoring of the large-scale reaction have been established, translating the outcomes of the reagent reduction exercise to a scalable, reproducible process reducing further the OPEX cost of the process ; and improving leaching efficiency have also been achieved.
A further key step which has been added to the NUOVOpb process has enabled the complete removal of all paste additives – carbon black, barium sulphate and organic fibres are isolated without destroying their structural integrity. These additives, isolated in their pure form, can potentially be separated and reused in the battery production process or other industries.
As a result not only is our leady oxide purity equivalent to that of the highest quality lead ingot-derived leady oxide, but we now operate (to the best of our knowledge) the only scalable recycling technology which allows isolation and reuse of the battery paste additives.
The significant benefit for end users of NUOVOpb is the 22% improvement in energy capacity and 50% increase in battery life. The higher energy capacity and ability to customise its structure will open new markets for LAB use, by being both LAB ready (a secondary process can add as much as €250/tonne PbO, consuming 350 MWh/10,000 LABs processed) and having a longer life thereby reducing replacement costs. NUOVOpb is also 30% more efficient than producing PbO from virgin lead, and 50% more efficient than producing it through secondary smelting.
NUOVOpb will achieve >60% more gross profit than pyrometallurgical processes by creating value-added products such as LAB-ready PbO and sodium sulphate; eliminate the need to control SOx and NOx emissions with expensive abatement technology; and by producing 5,000 MWh energy that can be captured and used in another part of the system.
Pilot plants in smaller territories and areas where pyrometallurgy is unsustainable, will be successful through processing small quantities (as low as 1,000 tonnes per year) and transport costs will be reduced by being situated close to waste LABs. Operating a 25,000 tonnes/yr plant, which is anticipated as being the average size plant sold, a licensee will see a payback on investments within 10.8 months. On a 10,000 tonnes/yr plant, the payback would be within 1 year and 3 months.
