<![CDATA[Marble quarrying and processing are resource-intensive industry that contributes significantly to local economies while generating substantial environmental and social challenges. This study assessed the level of eco-process innovation implementation among marble quarrying and processing firms in Romblon Province, the Philippines’ primary marble-producing area. Using a descriptive research design, data were collected from 18 registered enterprises through a sector-specific, expert-validated instrument grounded in established environmental innovation frameworks. Descriptive statistics, including mean and standard deviation, were employed to establish a baseline profile of eco-process innovation practices. The results reveal a moderate overall level of eco-process innovation implementation. Firms exhibited high adoption of low-cost, compliance-driven practices related to energy efficiency, dust suppression, wastewater treatment, logistics optimization, and occupational health and safety. In contrast, capital-intensive, technology-dependent, and socially transformative innovations, including renewable energy use, advanced waste valorization, modern deposit evaluation technologies, comprehensive noise and vibration mitigation, and post-extraction land rehabilitation, showed low to very low levels of implementation. These patterns reflect the financial, technical, and institutional constraints commonly faced by small and medium enterprises in the marble sector. The findings highlight the need for integrated policy support, capacity-building initiatives, and collaborative mechanisms that advance both environmental performance and social sustainability. The study provides a validated baseline framework to support future longitudinal, comparative, and impact-oriented research on sustainability-oriented innovation in resource-intensive industries.]]>
