Recycled rye straws are a promising alternative to single use plastics.

An Adelaide start-up Mister Rye is developing rye-cycling drinking straws made from the hollow stalks left from harvesting rye.
 
These straws are able to be put through the dishwasher and reused in the home setting.
 
Co-founder Marion Vigot says "A single-use plastic ban is coming in South Australia next year, so [they] are hoping to offer these straws as a suitable alterative for SA first, but then Australia as a second step."
