Recycling Insights1

What are the most important KPIs for a Recycler

Recycling InsightsTop 5 KPIs* for a sustainable development and business oriented return on investment:

● Recycled products must be Perfectly separated: to prevent any contamination and optimize plant production

● Recycled products must have High output Quality: to maximize the economic P&L topline and bottomline

● Keep the Production Cost low: Energy, Gas and Oxygen consumption affects for ~66% of the Smelting and Refinery total costs*

● Keep the Environment safe: to drastically reduce the Lead fumes and Air-pollution, Toxic particles are still very common especially in developing countries (WHO 2017)*

● Competitive commercial Price of the Plant: to optimize the investment of the engineering/innovation gained

*A review of published literature on exposures from formal-sector lead-acid battery manufacturing and recycling plants in developing countries found that seriously elevated blood and airborne lead concentrations were common (Gottesfeld & Pokhrel, 2011) - Recycling used lead-acid batteries: health considerations - World Health Organization 2017 (ISBN 978-92-4-151285-5)*Questionnaire Analysis based on recycler’s feedback and information collected internally in 2021*Calculation based on ROI 60 tdp ULAB Recycling example, internal analysis 2021

Gravity Breaker2

Used Lead-Acid Battery Breaking new process

The technology is leveraging on natural forces such as Gravity and Inertial Mass in every key separation process, perfectly balanced over the entire chain with an innovative GME process to obtain the separation of all the 5 elements composing a ULAB (PP, PE, Pb paste, Grids, Poles) keeping our highest quality while reducing*:

● Waste formation● Sulphur presence in the DS Pb paste● Smelting and Refinery time and cost

giving a new ecological turn to the Recycling path

*to be intended “down to maximum” based on internal calculation considering 1 hour cycle compared to a standard full cycle of 4/4.5 hours to obtain the Hard Lead Bullion

Benefit in Smelting phase

● Total cycle time: 1 hour (with automatic vibrating channel loader)

● Natural gas consumption (100% oxy-combustion): <15 Nm3/ton of charge

● Low melting temperature: max 650 ° C● Longer Refractory life: ~2 years ● No S02 pollution● Minimal waste formation● Minimal Pb waste presence

● Total cycle time: 4 / 4.5 hours (with automatic vibrating channel loader); 3 / 3.5 hours (for DS Pb paste)

● Natural gas consumption (100% oxy-combustion): <25 Nm3/ton of charge (20% less for DS Pb paste)

● Low melting temperature: max 1000 ° C ; max 850 ° C (for DS Pb paste)

● Minimal waste formation (for DS Pb paste)● Minimal Pb waste presence
