Mineralised aggregates
Commercially demonstrated components · local validation required
Conditioned mineral residues assessed as aggregate replacement. Local ash chemistry, leaching and construction specifications determine suitability.
Products & outputs
The material becomes the product.
Waste can become a potential local resource. CIAP prioritises mineral and construction-material recovery, with energy and water as secondary value streams—not guaranteed outputs.
Primary materials
Local resources instead of imported materials.
Construction blocks
Established production methods · CIAP products require validation
Potential local block manufacture using compliant recovered mineral material, subject to mix design, durability and strength testing.
Cementitious materials / SCM
TRL 4 research · requires validation
Biomass-derived supplementary cementitious materials investigated for partial substitution in construction mixes. Performance is feedstock-specific.
Foamed concrete
TRL 4 research · requires validation
A potential lightweight construction pathway for suitable MSW-derived mineral fractions. Product safety and performance must be demonstrated.
Mineralised and potentially vitrified aggregate routes require process selection and product testing. Vitrification is not represented as a validated CIAP installation. No ash fraction is automatically suitable for construction.
Distinct ash resources
Different residues. Different validation routes.
Established route · APCR
Air-pollution-control residue.
APCR is the primary material in the established accelerated-carbonation aggregate route. This provides a technology precedent—not evidence that the integrated CIAP platform is already demonstrated.
RPU development objective · IBA
Incinerator bottom ash.
Adapt the process and plant so IBA can potentially achieve comparable aggregate performance and applicable leaching requirements. The opportunity is to extend the usable mineral resource beyond APCR—not to claim that IBA compliance has been achieved.
APCR and IBA are distinct residues, not interchangeable feedstocks or an automatic combined mix. Each route requires characterisation, suitable treatment, physical-property and leaching tests, and approval for the intended end use. Remaining unsuitable residues need compliant management.
Biomass
Recover value before residual treatment.
- 01Feedstock assessment
- 02Potential chemical extraction
- 03Residual thermal conversion
- 04Cementitious material testing
Chemical extraction and biomass-derived SCM are feedstock-specific research pathways. Suitable organics also have a parallel composting route; they are not required to pass through thermal treatment.
Secondary outputs
More useful value, where feasible.
Secondary value streams · subject to feasibility and demand
- Recovered metals and other materials
- Feedstock-specific chemical products
- Useful heat
- Electricity · PV / BESS support
- Potential desalinated water
- Compost / soil amendment
No water output or zero-residual-waste outcome is guaranteed. Mineralisation may generate carbon benefits, subject to verification.
Local employment
Potential jobs across the whole resource pathway.
Local materials production can support employment beyond the processing plant: skilled operations, maintenance, deliveries and shared services. Training and local workforce development would form part of deployment planning.
Block and aggregate manufacturing
Potential roles in block manufacture, aggregate production, material testing, quality control and product dispatch—keeping more construction-material value locally.
Metals extraction and recovery
Sorting, metals separation and recovery, equipment operation and preparation of recovered metals for local use or onward sale.
Thermal treatment and waste-to-energy
General thermal-treatment (incineration) operation, emissions monitoring, maintenance and site safety, with waste-to-energy operating roles where energy recovery is viable.
Sand batteries and heat delivery
Where feasible, sand-battery thermal-storage operation and maintenance, alongside logistics and deliveries for useful heat services.
Desalination and water delivery
Potential desalination plant operation, water-quality monitoring, maintenance, storage and water deliveries where a viable, approved water system is included.
Marine work and disaster response
Potential barge crews, marine engineering, mooring and transport roles where barge deployment is feasible; post-disaster response planning, logistics and safe debris-processing operations where authorised.
These are potential employment pathways, not confirmed jobs, recruitment offers or job-count forecasts. Roles depend on feasibility, local demand, funding, approvals, safety requirements and training. Energy, sand-battery, desalination, marine and disaster-response activities are conditional options, not committed services.
Product assurance
A product is only useful if it is safe and specified.
Validation must cover chemistry, contaminants, leaching, strength, durability, quality control, applicable standards and local offtake. Historic landfill restoration needs separate assessment, remediation and approval. Carbon benefits remain subject to verification.
