Solution

Aluminium can be recycled multiple times. Unlike other materials, aluminium does not lose its unique properties after recycling. It can be melted down and reformed without losing any quality, and the process can be repeated over and over again. Recycling aluminium saves about 95% of the energy it would take to produce new aluminium from raw materials.

Wood can also be recycled multiple times, but the process is more complex and the quality of the wood can degrade with each cycle. It can be chipped and used in composite materials or as mulch, compost, etc.

Organic materials like food waste and yard waste can be composted and used to enrich soil, but this is a different process than recycling.

Plastic can be recycled, but not infinitely. Each time plastic is recycled, the polymer chain grows shorter, so the plastic loses some of its quality. This is called downcycling. After being recycled 2-3 times, plastic is usually no longer usable.

So, the material that can be recycled multiple times among the options given is Aluminium.
