Tree branches provide the mate

Tree branches provide the materials for safe and natural water filters

Xylem is a thin material that makes up the interiors of non-flowering trees. This straw-like conduit material draws water up from the ground to nourish trees and is interconnected with membranes that filter out sap and bubbles from the water. Researchers from the Massachusetts Institute of Read More...

Earth-friendly material filter

Earth-friendly material filters pollutants out of stormwater

While it’s often overlooked, stormwater has great potential to solve the problem of strained water supplies in urban areas. One of the main reasons why this resource has gone mostly untapped is because stormwater picks up toxic chemicals as it runs through streets and gutters. Now that may no Read More...
