50 Investible Opportunities for a New Nature Economy Supplementary Appendix 2026

64 Sewage nutrient recovery technologies capture phosphorus and nitrogen from municipal or industrial wastewater (e.g., struvite crystallization, ammonia capture) and turn them into usable fertilizer inputs. – Reduces nutrient pollution: Captures phosphorus and nitrogen from wastewater before discharge, cutting eutrophication in water bodies – Reduces mining, synthetic fertiliser dependence: Turns recovered nutrients into fertilizers, reducing dependence on mined phosphates and synthetic nitrogen, mitigating resource depletion, GHGs, and land Archetype Scalable Nature impact Transformative impact Suitability of financing and de - risking instruments Technological / process maturity Capital intensity Scalability Bonds Loans Equity Other De - risking Commercial bonds Thematic bonds Sustainability - linked bonds Impact bonds Commercial loans Thematic loans / project finance Sustainability - linked loans Impact loans Commercial equity Private equity Venture capital Impact equity Blended finance Insurance Advanced market commitments Legend: Low High Low suitability High suitability Payments for ecosystem services Land ecosystem Ocean ecosystem Freshwater use Resource use Pollution Co - benefits Climate Social ✓ ✓ – Proven and scalable retrofit solution: Commercial struvite and brushite recovery systems offer modular, low - risk integration into existing wastewater plants. However, capital intensity varies with technology choice, plant scale, and feedwater characteristics. – Financing suitability characteristics: Wastewater treatment operators face moderate to substantial capital expenditure for retrofitting or installing nutrient capture and processing systems. Commercial loans and project finance provide foundational financing vehicles. Sustainability - linked loans offer additional value by tying financial terms to achievement of metrics such as phosphorus and nitrogen recovery rates or reductions in effluent nutrient loads. Insurance products addressing operational risks and liability exposures may be required.– Additional revenue streams : Sustainable fertilizer alternatives can be sold by wastewater treatment operators . – Lower operating costs: Use of nutrient recovery technologies can reduce wastewater discharge, chemical and sludge handling costs.
