Vision and Mission of Bio-Diversity

At Bio-Diversity, we take what was once thought of as waste products (recycled hardwood, sawdust and shavings) and turn them into viable alternative heating sources (wood blocks and wood pellets) that are environmentally-friendly and give people a clean and convenient way to save on heating costs.

Bio-Diversity is dedicated to our employees, customers and the communities around us. We strive to maintain a healthy work environment where our team members feel welcomed, empowered, and enjoy opportunities to grow professionally. For our customers, we devote our efforts and energy to creating the highest quality alternative heating products – like Envi Blocks and Tru-Wood – and providing exceptional service on every interaction. We have geographically positioned our company along Route 522 in Selinsgrove, Pa. so we can minimize the costs – and carbon footprint – of shipping our products to our customers and transporting the raw materials we need for manufacturing. We would love to find out how we can serve you.

Alternative Home Heating Solutions

We produce wood blocks and wood pellets and give you a clean and convenient way to save money on heating costs. Our company’s management team has decades of experience in manufacturing high-quality products. We bring not only an extensive product background to our operations, but we also share a fresh perspective that facilitates innovation and makes superior customer service to our dealers a top priority.
