Introduction
A major public dental hospital in Stockholm committed to aligning its operations with Sweden’s ambitious environmental goals, particularly the target for the Swedish healthcare sector to become carbon neutral by 2045. While providing excellent clinical care, the facility’s environmental performance lagged behind national benchmarks, with excessive energy consumption, significant medical waste generation, and water usage patterns that failed to reflect Sweden’s sustainability values. A comprehensive green transformation was needed to modernize the facility’s environmental performance while maintaining clinical excellence.
Challenges
The hospital faced multiple environmental challenges that required systematic addressing. Energy consumption was inefficient, with outdated HVAC systems operating continuously regardless of occupancy and medical equipment left powered on overnight, contributing to excessive electricity use. Water usage patterns were unsustainable, with traditional dental units consuming approximately 500 liters per hour per chair and no water recycling systems in place. Waste management practices fell short of potential, with limited segregation of medical waste leading to unnecessary incineration of recyclable materials and single-use device culture dominating clinical practice. Additionally, supply chain impacts were significant, with procurement decisions based primarily on clinical and cost considerations without systematic environmental criteria, and substantial carbon footprint from transportation of supplies and instruments for reprocessing.
Solution: Comprehensive Green Dentistry Program
The transformation implemented a multi-faceted program addressing all aspects of environmental impact. Energy efficiency measures included installation of smart HVAC systems with occupancy-based zoning and scheduling, replacement of conventional lighting with LED fixtures with motion sensors, and power management systems that automatically placed equipment in low-power mode during non-clinical hours. Water conservation solutions involved retrofitting dental units with vacuum suction systems reducing water consumption by 90%, installing water-efficient sterilizers and washer-disinfectors, and implementing rainwater harvesting for non-clinical uses like irrigation and toilet flushing. Sustainable materials management introduced comprehensive waste segregation with dedicated streams for recycling, composting, and specialized treatment of dental materials like amalgam, transition to reusable clinic gowns and sterilization wraps, and instrument reprocessing protocols that maximized reusable items while ensuring infection control. The green procurement policy established environmental criteria for all new equipment and supply purchases, preference for suppliers with verified environmental management systems, and inventory management that minimized stock levels and associated storage energy while maintaining essential availability.

Implementation Process
The transformation followed a structured approach with strong staff engagement. Baseline assessment and target setting began with comprehensive environmental auditing to establish performance benchmarks and setting specific reduction targets for energy (40%), water (50%), and waste (30%) over three years. The initial implementation phase focused on “quick wins” including lighting replacement, waste segregation rollout, and behavioral change campaigns, generating early momentum and staff buy-in. Major infrastructure upgrades required careful phasing to minimize clinical disruption, with dental unit retrofits scheduled during holiday periods and HVAC replacement conducted section by section over six months. Staff engagement and training involved establishing “green champions” in each department, incorporating sustainability education into mandatory training programs, and regular communication of progress toward environmental targets. Continuous monitoring and improvement were enabled through installation of smart meters for real-time tracking of energy and water use, quarterly sustainability reports reviewed at board level, and annual reassessment of targets based on performance and new technological opportunities.
Results and Impact
The environmental transformation achieved impressive results across all targeted areas. Carbon footprint reduction saw a 35% decrease in overall carbon emissions, exceeding the initial target, with energy consumption reduced by 42% through equipment and behavioral changes, and water usage cut by 58% primarily through dental unit retrofits. Waste management improvements included 75% diversion of clinical waste from incineration to recycling or alternative treatment, 30% reduction in total waste volume through process changes and reusable items, and complete elimination of mercury-containing waste through material substitution. Operational benefits emerged with 15% reduction in utility costs despite rising energy prices, improved staff satisfaction with 85% of employees reporting pride in the hospital’s environmental leadership, and enhanced public reputation with positive media coverage and patient comments about the hospital’s environmental commitment. The hospital received the Swedish Healthcare Environmental Award in its second year of transformation, recognizing its leadership in sustainable healthcare delivery.
Conclusion
The Swedish hospital’s green transformation demonstrates that environmental sustainability and clinical excellence are not just compatible but mutually reinforcing in healthcare settings. The project has become a reference case for the Nordic healthcare sector, with numerous hospitals adopting similar approaches based on its demonstrated success. The systematic methodology—combining infrastructure investment, process redesign, staff engagement, and continuous measurement—provides a transferable framework for other healthcare facilities seeking to improve their environmental performance. Perhaps most importantly, the project challenges the assumption that high-quality dental care must come with significant environmental cost, showing instead that through thoughtful design and operation, dental facilities can dramatically reduce their ecological footprint while maintaining—and in some cases enhancing—clinical care quality. The hospital continues its sustainability journey, with plans to achieve carbon neutrality by 2035, a full decade ahead of the Swedish healthcare sector’s national target.
