I don't usually like to stereotype (kidding), but this is as "Portland" a thing I have ever seen: Deweywood is a two-man (Trent Waneka and Evan Parker) small, local company making environmentally conscious plywood wall displays for your vinyl records. I'm counting at least three types of nerding going in that concept.
Plywood from the mighty Moso is 10 times stronger then most hardwoods. It can grow to heights of 50 to 60 feet in less then two years. It reaches maturity and can be harvested after 4 to 6 years of growth, comparable wood species typically take about 30 to 60 years to reach maturity. The day after a stalk of Moso is harvested, there will be 4 to 7 new plants beginning to regrow. No planting is necessary, because Moso bamboo is regenerated after a harvest through its rhizomes. Rhizomes are found in Moso bamboo’s underground stem system. Think of a chunk of ginger, which is a rhizome, ginger can be sliced into many pieces and any one of those pieces can be planted to grow a new ginger plant. This rhizome biology is the key element to bamboo’s sustainability.
