    When was the last time you used plastic plates? Next time, why not try some edible ones? You’ll help the environment and your guests won’t go hungry.

“I used to work in school catering and saw a lot of money being thrown away. I thought that was criminal, so I decided to do something about it,” said Italian school chef Tiziano Vicentini.

Now, Vicentini has an amazing range of edible plates for schools. The plates are made out of bread dough, so you can eat them afterwards. “These dishes cost a few pennies each and are either eaten by the kids, or go into recycling bins for animal food,” explained Vicentini, 50, of Milan.

But now other companies are developing edible plates, too. The Edible Plate Company offers edible plates, bowls, trays and cups. Their products are environmentally-friendly, 100% biodegradable and can be used for all types of catering and home use. And they’re made from a natural plant. After use, they can be fed to animals or left to degrade naturally. They also have a range of cutlery (餐具）made from corn and potato starch (淀粉).

These plates will also help reduce the amount of plastic we create. Waste from plastic causes damage to the environment, costing governments millions in waste management. Plastic bags often end up in landfill sites. And the burning of plastic waste causes toxic gases that pollute the air.

In response to this, governments around the world are introducing tough recycling regulations. And many shops are offering biodegradable plastic bags and eco-safe packaging on their products. To help matters, the International Organization for Standardization (the ISO) has also developed a system to evaluate the biodegradability of products, with a certification and logo scheme. Meanwhile, how about a nice plate for lunch?
