What Are PCBs?
Polychlorinated biphenyls (PCBs) are a group of synthetic organic chemicals that were widely used in electrical and industrial applications for decades. Commonly found in transformers, capacitors, heat transfer systems, rail cars, and certain coatings, PCBs were valued for their stability, low flammability, and ability to effectively insulate and maintain electrical currents. While these properties made… Read more
Demolition vs. Deconstruction: Understanding the Key Differences
While both demolition and deconstruction can achieve high material recovery rates, often reclaiming up to 90% of materials, the primary difference lies in the methods used to remove those materials. Deconstruction is a labor-intensive process that focuses on carefully dismantling a structure by hand. Building components are removed piece by piece to preserve materials for… Read more
