Styrofoam lunch trays recycled into paving bricks

Two bricks are made from every 1,200 lunch trays.

May 28—Instead of sitting in a landfill for centuries, used Styrofoam school lunch trays are now being converted to paving bricks in Michigan City, Ind., home to one of just a few of the newly invented StyroGenies.

The 700-pound stainless steel StyroGenie is loaded every day or two with 600 Styrofoam lunch trays straight out of the trash at Lake Hills Elementary School. Ten hours later, after undergoing a process called densification, the trays are converted into a single square brick that feels like glass or tile but is solid as a rock.

In a time of growing health consciousness, it might not be enough anymore for food to be merely filling. According to Technomic’s 2016 Healthy Eating Consumer Trend Report , diners are looking for food with a function, such as those with high protein content, immunity-boosting properties, antioxidants, probiotics and more. The data suggests 63% of consumers see these foods as healthier than those without any specific nutritional function—and would be more likely to buy them.

But are those stated preferences translating on an operational level? There, the answer is less clear. Baby...
