What's up everybody - We're coming at you here live from our Viv offices and today we're giving y'all 4 quick tips to make sure that your corn cups are indeed composted. Before we do that though, we want to give you a quick run down on how corn... becomes a cup.

So, field corn is harvested, the sugar from the corn (the dextrose) is then extracted, that dextrose is turned into lactic acid, lactic acid become polylactic acid, and then those polylactic acid pellets are molded into your corn cup.

Tip #3 - You want to make sure that you're getting the cups to a commercial composting facility. Why this is really important. These cups need a high heat to break down. Typically commercial facilities reach up to 55-60 degrees C. Those high heat levels are whats needed to break down the cups.
