A process for recovering materials from a black mass material obtained from lithium-ion batteries can include: i) conveying a black mass material as a black mass solid stream; ii) leaching the black mass solid stream to form a pregnant leach solution and residual solids; iii) separating the pregnant leach solution from the residual solids; iv) isolating a copper product from the pregnant leach solution; v) isolating an aluminum (Al) and/or iron (Fe) product from the pregnant leach solution; vi) isolating a manganese (Mn) product from the from the pregnant leach solution; vii) isolating a cobalt (Co) product from the from the pregnant leach solution; viii) isolating a nickel (Ni) product from the from the pregnant leach solution; ix) isolating a salt by-product from the pregnant leach solution; and x) isolating a lithium product the pregnant leach solution.

The invention involves an automatic shut-off waste disposer that may be activated with a control module, which utilizes a programmable automatic shut-off routine. This enables a user to turn on the garbage disposer and walk away without having to turn the disposer off. In exemplary embodiments, activation of the disposer includes actuation of a solenoid valve for injecting a stream of water flow into the dispenser chamber in order to facilitate a proper water flow while the disposer is actively disposing of food waste. In some exemplary embodiments, activation of the disposer may be achieved via a user-activated pneumatic actuator, which may be installed in proximity to the sink to which the disposer is coupled. In some exemplary embodiments, the disposer implements a sensor for automatically shutting of a motor of the disposer upon a predetermined event.
