Procurement, waste generation and water management are three major categories where dental practices could potentially become more sustainable. This is in line with a new study that assessed the effectiveness of changes suggested by the Royal College of General Practitioners’ Green Impact for Health Toolkit, which aims to help dental practices become more eco-friendly and reduce their carbon footprint. Dental Tribune International discussed the topic further with lead author Peter Suresh, an undergraduate student in dental science at Dublin Dental University Hospital in Ireland.
