Island manufacturers face unique challenges. Limited resources demand maximum efficiency, yet achieving this often costs more. Puerto Rico exemplifies this challenge. The island imports approximately 85% of its energy from fossil fuels, pays electricity rates nearly double the U.S. mainland average, and operates with limited waste management infrastructure. For manufacturers, these constraints translate to operational costs that can exceed mainland facilities by 20-40%, making sustainability not just an environmental imperative but an economic necessity.
While the facility is one of the most recent to join ABB’s Mission to Zero™ program, it’s certainly not the least innovative. The site, which manufactures Ty-Rap® cable ties, Sta-Kon® wire terminals, and Deltec® cable ties and accessories, has transformed these challenges into catalysts for innovation on its journey to net zero – resulting in reduced emissions, lower costs, and measurable community impact across Puerto Rico.
Engineering Resilience for Island Reality
When Edwin Delgado, General Manager at the site, and his team invested in solar panels to cover 75% of the Deltec building’s energy usage, they didn't just install a standard photovoltaic system. They engineered it for Puerto Rico's reality, including modular and removable panels designed to be quickly collected and stored when hurricanes are imminent.
This hurricane-ready design exemplifies how Vega Baja’s sustainability initiatives address both environmental and operational resilience. The facility now generates 316 MWh annually from solar power while maintaining the flexibility to protect critical infrastructure during tropical storms that regularly impact the island.
The broader transformation accelerated in 2021 with investments in high-efficiency molding machines and continued through systematic upgrades, including HVAC improvements and chiller insulation in 2024, followed by the installation of EV chargers and LED lighting, replacement of outdated air compressors, and ABB energy management deployment in 2025.
These efforts have reduced annual CO₂e emissions by more than 1,400 tons and, combined with the facility’s 316 MWh solar installation, equate to taking more than 325 gasoline-fueled cars off the road annually. Together, these initiatives help address Puerto Rico's energy reliability challenges through reduced grid dependence while delivering measurable impact.
Circular Solutions address Environmental Constraints
Operating on an island with limited recycling infrastructure demanded a creative, more circular approach to managing material waste. The site now sends EDM machine resin cylinders previously disposed of as hazardous waste to a local supplier who cleans and returns the resin for reuse, diverting 100% of potential waste.
To conserve water, the site captures condensation from its adiabatic cooling system and reuses it in a fully closed loop. Rather than requiring new water to be added weekly to compensate for condensation loss, the new system significantly reduces overall consumption.
The site incorporates up to 25% of manufacturing scrap back into production. Remaining material is sold to a local recycling facility that processes and regrinds plastic waste for molding companies worldwide. Some recycled material goes to an island manufacturer, creating everyday products like brooms and planters, keeping materials in the local circular economy while supporting Puerto Rican businesses. These efforts to reduce, redirect and repurpose waste have helped the site achieve a Zero Waste to Landfill UL2799 Silver Certification.
Community Impact Beyond the Factory Walls
Vega Baja's sustainability initiatives have an economic and environmental ripple effect throughout the region. Recycling partnerships support local companies, while energy efficiency improvements reduce demand and directly address Puerto Rico's limited generation capacity.
The facility's location in tourist-oriented Vega Baja, which continues developing sustainability programs to protect its beaches and the Tortuguero Lagoon, makes the site's environmental leadership particularly visible. The team also actively shares learnings through the Puerto Rico Manufacturers Association's Sustainability Summit, where they recently received the Eco Label and Special Projects/Community Awards.
A Model for Resilient Manufacturing
The journey has fundamentally changed how the team approaches operations. Delgado emphasizes, “Sustainability and manufacturing go hand in hand. We never viewed them as separate activities.” Proper planning makes processes both safer and more efficient – a lesson learned through necessity in Puerto Rico's challenging operating environment.
Looking ahead, Vega Baja plans to expand building management systems to include all pneumatic equipment, transition to electric transportation, and continue compressor replacements. The facility aims to achieve 100% metered and controlled operations through the ABB energy management platform while exploring additional renewable energy opportunities.
ABB’s Vega Baja team has proactively addressed challenges to reach a level of achievement that few companies on the island have attained and contribute meaningfully to environmental protection – all while maintaining competitiveness despite higher operational costs.
