Magazines shouldn’t be composted – it’s better to recycle them instead.
Glossy paper, such as that used in magazines or take-away menus, is often coated in plastic or otherwise uses synthetic materials to achieve shinyness.
The inks used on brightly coloured magazines can sometimes be toxic too.
(Newspaper-like magazines or zines – black and white print on low quality paper – can be composted as if they are newspapers though.)
If you’d prefer to reuse them or can’t recycle them in your area, they can be used as the raw material in various crafts.
Also don’t forget to reduce if you can – some magazines let you switch to the greener (and often cheaper) option of reading them online or through phones/e-readers. Or if they’re popular, your local library might hold them. Finally, if you must buy them, pass them on to others before recycling them.
