Evaluating Financial Support Mechanisms for Robust Recycling Enterprises Managing Construction and Demolition Waste

Abstract

Construction waste recycling enterprises (CWRE) play a pivotal role in construction and demolition waste management. However, their potential in emerging economies remains largely untapped due to widespread absence and substandard operational conditions, largely attributable to financial barriers. This underscores the imperative of well-designed economic instruments (e.g., targeted subsidies, tax relief, concessional loans, etc.) to strengthen their financial viability within a dynamic environment. Despite their importance, existing research offers limited insights into the financial performance of CWRE under scenarios involving multiple economic instruments amid uncertain operational conditions. Addressing this gap is crucial for designing effective instruments that ensure long-term financial sustainability of CWRE. In response, this study develops a probabilistic financial model to evaluate the investment viability and financial sustainability of CWRE across diverse policy scenarios involving multiple economic instruments, explicitly incorporating uncertainties and variabilities in key operational parameters. The model integrates detailed cost structure, revenue streams, financing mechanisms, and policy-linked variables for scenario-based simulations that assess performance across modeled scenarios. These include a baseline case without external support, interventions based on CAPEX or OPEX subsidies, and hybrid approaches combining both, thereby providing a structured evaluation of synergies, policy effectiveness, financial risks, and the critical factors determining project success or failure. For the case under consideration, CWRE remained financially unviable in purely market-driven contexts without external support and scenarios relying solely on CAPEX support. In contrast, OPEX and hybrid interventions proved particularly effective in stabilizing revenues, improving debt serviceability, and enhancing equity attractiveness, thereby enabling project success. These outcomes underscore the critical role of well-designed economic instruments over isolated fiscal measures in ensuring long-term financial sustainability. The analysis further identifies key failure drivers and outlines corrective measures, offering actionable insights to foster financially viable, scalable recycling enterprises.
