Procurement-fit structures
Project and contracting structures suited to the host, procurement pathway, financing requirements and operating model.
Circular infrastructure developer-investor
Turning waste into renewable energy and fertiliser
Proven solutions exist. We make deployment work.
Sustainalutions originates, de-risks and develops the projects that make this happen, turning difficult waste streams into valuable products. Our current focus is wastewater sludge and biosolids across Africa.
We bring proven technologies, local partners, finance and offtake together within one accountable project structure.
What we build
Starting with sludge and biosolids, designed to scale
Sustainalutions is building a broader waste-beneficiation platform, beginning where the need, evidence and project pipeline are strongest.
Depending on the opportunity, we may develop an integrated treatment facility, upgrade existing municipal infrastructure, establish a regional beneficiation centre or structure a downstream biosolids-to-product pathway.
Biosolids and sludge beneficiation
We develop projects that improve sludge treatment, plant capacity, stability and beneficial use. Solutions may combine thermal hydrolysis, anaerobic digestion, dewatering, drying, energy recovery and other technologies selected for the site.
Fertiliser and agricultural products
We develop downstream pathways that convert suitable biosolids into stable agricultural products through drying, granulation, blending, toll processing or structured offtake.
Over time, the platform can expand into imported sludge, industrial organics, co-digestion and regional waste-beneficiation centres.
What each party gets
Value for every side of the project
Municipalities and waste owners
Reduced disposal pressure, improved compliance, additional treatment capacity and long-term operational accountability.
Offtakers
Locally produced energy, agricultural products and other valuable outputs.
Financiers
Ring-fenced projects with defined feedstock, revenue, performance, delivery and operating responsibilities.
What we solve
Proven solutions often stall on local delivery barriers
Municipalities and industries frequently face waste streams that are costly to manage, difficult to permit and poorly served by existing disposal pathways.
Proven solutions exist, but projects stall when procurement, evidence, finance, approvals and offtake are not developed together.
Bankable commercial structures
Realistic treatment fees, clearly allocated risk, defined performance regimes and credible product or energy offtake.
Right-fit finance
Stage-gated capital combining suitable debt, equity, export credit and development-finance support.
Local evidence
Independent, university-linked testing and site-specific evidence, rather than relying only on international reference projects.
Approvals coordination
Early alignment of permitting, environmental approvals, procurement requirements and institutional responsibilities.
Built with, not for
Local engineers, contractors, universities, operators and stakeholders embedded from the start.
How we work
A repeatable engine from origination to operations
Sustainalutions acts as the developer-integrator, coordinating the specialist partners and commercial workstreams required to move a project from concept to operation.
01
Originate
Identify high-friction waste and infrastructure problems where proven solutions can create measurable economic and environmental value.
02
De-risk
Characterise the waste stream, test solution pathways and resolve the critical technical and commercial uncertainties.
03
Structure
Build the commercial and contractual structure, define feedstock and offtake, and align procurement, approvals and financing requirements.
04
Deliver
Contract and coordinate the OEM, engineering, EPC and financing parties under clear performance obligations.
05
Operate & Optimise
Coordinate KPI-backed operations and continuous optimisation to protect asset performance and project cash flows.
Evidence and traction
Evidence-led and moving forward
Sustainalutions is developing its first projects through local evidence, institutional partnerships and proven technology pathways.
First-of-its-kind local evidence programme
Sustainalutions is sponsoring a UKZN-led sludge-characterisation and transformation programme with eThekwini Water & Sanitation. Using a laboratory-scale Cambi thermal hydrolysis unit, the programme is testing local sludge and generating evidence to inform commercial-scale deployment.
Broader South African pipeline
Beyond eThekwini, Sustainalutions is developing opportunities across municipal wastewater, sludge beneficiation, regional infrastructure and industrial resource-recovery contexts in South Africa.
Partnered delivery model
Sustainalutions brings together specialist technology, engineering, research, finance and offtake partners within one coordinated project-development platform.
Partner Technology Track Record
More than 90 installations across 28 countries
Thermal hydrolysis reference base reported by Cambi, a technology partner for selected sludge projects.
Performance and product outcomes depend on feedstock quality, the baseline treatment process and system configuration. Sustainalutions validates project claims using site-specific data.
Research and academic partners
University of NairobiThe University of KwaZulu-Natal leads our current sludge-characterisation programme with eThekwini Water & Sanitation.
Delivery partner ecosystem
Specialist partners on one coordinated platform
Sustainalutions brings specialist partners onto one coordinated delivery platform, allowing each party to contribute its core capability without having to become the project developer.
Technology and OEM partners
Proven technology, equipment supply, commissioning, training and performance guarantees.
Engineering and delivery partners
Local and international engineering, EPC, operations and maintenance capability.
Capital and offtake partners
Development finance, commercial lenders, strategic equity, energy offtake and product-market pathways.
Where we work
A South African foundation with selective regional expansion
South African founded and anchored, with local research, engineering and delivery partnerships. We prove the model where our evidence, relationships and delivery capability are strongest, while selectively developing opportunities in adjacent African and Middle Eastern markets.
