Barbecue

Material A
Cast Iron. An iron-carbon alloy with a low melting temperature, but also with a strong resistance to wear and deformities.

Cast iron in itself can be recycled, as it is reusable and can be melted down into reusable steel as well.

Disposal: Curbside disposal, or a Drop-Off Depot which will accept barbecues.

Material B
Sheet Steel. Thin, malleable metal that can be moulded and cut.

Sheet steel can and should be recycled as the steel can be reused or melted down for further production.

Disposal: Curbside or a Drop-Off Depot which will accept barbecues.

Material C
Stainless Steel. A type of steel with a strong resistance to corrosion, which makes it rather valuable in creating an assortment of appliances and machines. Stainless Steel can also be recycled as it is reusable and can be melted down into reusable steel as well.

Disposal: Curbside or a Drop-Off Depot which will accept barbecues.

Best Alternative
A barbecue itself does not have a significant impact on the environment based on its composite materials alone. When selecting a barbecue, it is important to pick one that will have a longer life to prevent having to dispose of it sooner.
