ALCEDO CIRCULAR ENERGY
We aim to build lasting local resource cycles by combining feedstock-specific equipment with quality checks and operational support.
From collection and recovery to use and ongoing operation.
01 / CIRCULAR
We assess the volume and properties of used cooking oil and residues, then select suitable equipment and end users. Each site is planned from collection through ongoing operation.
Check feedstock volume and properties,
and supply reliability.
Select suitable equipment
and operating methods.
Check quality, acceptance criteria
and intended uses.
Assess maintenance, records, contracts
and financial viability.
ALCEDO_CORTEX: a concept linking feedstock, operation, quality and shipment records to support human review and decisions.
02 / PRODUCTS & TECHNOLOGY
Equipment and configurations are assessed against required throughput, recovered-product quality and installation conditions.
Feedstock oil undergoes reaction, separation and vacuum distillation to recover a biodiesel fraction. Refining the separated crude glycerin in a standalone GLY unit is considered separately.
Reaction → Separation → Vacuum distillation → Quality checks
Fuel use is determined after checking batch quality and the receiving equipment's acceptance requirements.
A standalone unit for pretreating, separating and refining crude glycerin from the BIOD process. Potential uses as feedstock or fuel are assessed against composition and end-user requirements.
Pretreatment → Separation → Refining and recovery → Composition checks
Purity, recovery rate and throughput must be verified for each feedstock.
Suitable residues are treated with superheated steam to recover char and other materials. Batch or continuous operation, and stationary or vehicle-mounted configurations, are selected according to feedstock properties, volumes and site conditions.
Feedstock is loaded on trays and treated with the doors closed. After cooling, trays are removed and char or other recovered materials are collected.
Tray loading → Treatment → Cooling → Unloading and recovery
Plan trays, handling equipment, door clearance, loading and recovery routes, and maintenance space together.
A continuous process is arranged within the factory, from feedstock supply through superheated-steam treatment to cooling and recovery.
Feedstock supply → Treatment → Cooling and recovery
Check feedstock handling, steam, power, cooling and exhaust connections, recovery equipment and maintenance access.
Operation at the feedstock source is considered by moving the unit to the site. Mounted equipment and external supply and recovery facilities are designed separately.
Site setup and connections → Feedstock supply → Treatment, cooling and recovery
Check vehicle dimensions and weight, parking and working areas, external steam and power supplies, and feedstock supply and recovery arrangements.
BPR stands for Batch Pyrolysis Reactor; CPR stands for Continuous Pyrolysis Reactor. Throughput, temperature and dimensions are defined for each model and feedstock. Images are concepts and do not guarantee physical equipment specifications or performance. Recovered-material uses depend on composition and acceptance criteria.
03 / ALCEDO_CORTEX
An AI and data platform concept bringing together procedures, operating records, quality results and past responses. Staff review the evidence, make decisions, take action and record outcomes.
Present relevant procedures and response histories together with their sources.
Link feedstock, operations and quality, identifying checks to make and missing information.
Draft daily reports for staff to check figures and supporting evidence before approval.
Start with one selected line.
Compare time, errors and review workload using the same tasks as existing procedures. Results inform whether to move gradually to on-site edge infrastructure.
People decide. PLCs and other control systems handle equipment and safety.
Benefits and performance will be assessed in a proof of concept. PLC command integration, optimization and predictive maintenance are later-stage considerations.
04 / APPLICATIONS
Explore fuels, biochar and materials from agricultural and food-processing oils and residues. Recovery potential is assessed against feedstock properties and end-use requirements.
Recovering resources from pulp and skins
Potential uses: agricultural biochar / solid fuel
Check feedstock volumes and seasonality, pretreatment requirements, char composition and safety, and field application conditions. Colombia is a candidate setting for a trial.
Recovering resources from milling residues
Potential uses: solid fuel / soil amendments
Check fiber handling, ash and residual oil, product quality, heat balance, emissions and competition with existing uses.
Separate routes for rice bran oil and residues
Potential uses: biodiesel / solid fuel / char-based materials
Check oil acid value and impurities, fuel quality and suitability, and each residue's ash content, handling and heat balance.
Recovering resources from processing residues
Potential uses: agricultural biochar / solid fuel / adsorbents
Check collection, storage, pretreatment requirements, and char composition and safety. Adsorbent applications require additional processing and application-specific testing.
We aim to reduce residue-handling burdens, recover fuels and materials, and connect with local users. Evaluation covers soil effects and safety for agricultural uses, quality and energy balance for fuels, and application-specific performance for materials.
These are application concepts. General research findings are not evidence of ALCEDO equipment performance. Performance, economics and environmental benefits require feedstock-specific verification; uses depend on test results and acceptance criteria.
PROJECT / CAMBODIA
ALCEDO will participate in Asian Gateway's decarbonization project as a partner evaluating superheated-steam pyrolysis technology.
ALCEDO will evaluate the pyrolysis characteristics of Cambodian rice husks, equipment specifications and suitability for local operation. The wider project explores combining agricultural biochar use with methane reduction through paddy water management.
Rice husks from milling
Evaluate pyrolysis characteristics, specifications and local suitability
Assess agricultural use, carbon storage and commercial feasibility
The project is at the feasibility-study stage. Commercial operation, agronomic benefits, emission reductions and credit issuance are not confirmed.
Asian Gateway's proposed project was selected under Japan's Ministry of Economy, Trade and Industry FY2025 Supplementary Budget Global South Future-Oriented Co-Creation Project Subsidy (Small-Scale Demonstration / Feasibility Study Program). Grant approval was received on September 18, 2026.
An integrated model is being explored alongside Asian Gateway's separate AWD study supported by Japan's Ministry of Agriculture, Forestry and Fisheries. Alternate Wetting and Drying (AWD) manages paddy water intermittently rather than maintaining continuous flooding. Measurement, reporting and verification requirements are also assessed toward potential use under the Joint Crediting Mechanism (JCM).
