Batteria Domestica Riciclaggio: What Happens After the Lifespan?

The end of the lifespan: a growing issue

The first generation of batterie domestiche that were installed on a large scale around 2015-2018 is approaching the end of its lifespan. At the same time, the number of new installations is growing explosively. The demand for sostenibile riciclaggio of lithium-ion batterie — including LiFePO4 (LFP) batterie domestiche — is becoming increasingly urgent.

The good news: batterie domestiche are highly recyclable, and the industry is investing heavily in better riciclaggio technologies. Inoltre, a decommissioned batteria domestica is rarely truly 'spent': with 70-80% capacità residua, a meaningful second life is often possible.

What materials are in a batteria domestica?

To understand why riciclaggio is so important, you need to know what is inside an batteria LFP cell. The main components are:

• Lithium iron phosphate (LFP): cathode material — the most stable and less scarce cathode choice
• Graphite: anode material — mostly mined in China, mining has environmental impact
• Copper: current collectors and wiring — high recyclability
• Aluminium: housing and current collectors — valuable and highly recyclable
• Electrolyte (lithium salt in organic solvent): the most challenging component for riciclaggio — requires specialised processing

Riciclaggio processes: how are batterie processed?

There are three main processes for riciclaggio delle batterie, each with its own advantages and disadvantages:

Pyrometallurgy (smelting)

In pyrometallurgy, batterie are melted at high temperatures. This is a robust process that is widely applied, but it is energy-intensive and does not efficiently recover all materials. For batterie LFP, pyrometallurgy is less optimal than for batterie NMC due to the lower cobalt and nickel concentrations.

Hydrometallurgy (wet chemical processing)

Hydrometallurgy dissolves the batteria materials in acid and then separates the valuable metals. This process achieves higher material recovery than smelting and is the most suitable for batterie LFP. Companies such as Umicore, Fortum and the European BASF are investing heavily in hydrometallurgical riciclaggio of batterie domestiche.

Second life: an intermediate step before riciclaggio

Many batterie domestiche are not recycled immediately at the end of their primary lifespan. With 70-80% capacità residua, they are perfectly suited for applications with less demanding requirements:

• Stationary accumulo di energia at industrial level: decommissioned EV batterie and batterie domestiche are combined into large accumulo di energia parks
• Alimentazione di riserva systems for telecom towers: lower capacità is sufficient for backup applications
• Community storage: batterie are grouped for neighbourhood storage or homeowners' association projects
• Off-grid applications: caravans, boats and small off-grid dwellings are less critical about capacità

Manufacturer responsibility: the Batteria Regulation

The European Batteria Regulation (EU 2023/1542) imposes strict obligations on produttori of industrial batterie and EV batterie. Batterie domestiche partially fall under these rules. Key obligations:

Manufacturers must provide a batteria passport with material information. Minimum riciclaggio percentages apply (by 2027: 65% for lithium batterie, by 2031: 70%). Manufacturers are responsible for collection through producer responsibility (WEEE Directive). In pratica, this means: anyone who buys a batteria domestica from a reputable produttore (Anker, Dyness, BYD, Huawei) can expect a collection and riciclaggio system to be available.

How do you correctly dispose of your batteria domestica?

Nei Paesi Bassi, batterie domestiche are classified as hazardous waste and must not be disposed of with general waste. The correct disposal routes are:

1. Return to produttore or dealer: most produttori have a take-back programme. At HES, we collect old batterie upon delivery of a new system. 2. Municipal waste collection point (riciclaggio centre): large batterie are accepted as small hazardous waste. 3. Specialist batteria processor: for larger systems (>10 kWh), a specialised company handles the collection.
