In State College, Pennsylvania, I had the opportunity to tour the 2,400 square feet Matson &
Associates Eco-Building, home to three ecopreneurial enterprises: Matson &
Associates, an environmental assessment
services company, often engaged to provide «expert witness» testimonials on some of the most timely waste processes issues; Envinity, a green building and home energy audit consultancy; and Matson Biofuels, a company developing a more
ecological and non-toxic approach to making biodiesel called Green Biodiesel.
