Household-scale tofu industries can be integrated into Surabaya^s coastal resilience
strategy by adopting cleaner production methods that mitigate environmental
degradation while creating new economic opportunities. Rather than discharging
untreated liquid waste which drives high freshwater ecotoxicity and threatens aquatic
ecosystems producers can convert this waste into liquid organic fertilizer and
repurpose solid by-products into marketable food items like tempe gembus.
Additionally, implementing fuel substitution and water recycling can drastically
reduce the industry^s high Global Warming Potential of 529.5 kg CO₂--eq/day ,
ensuring these enterprises remain economically viable and sustainable without
burdening the city^s coastal resources
