BioJejak: Trust Infrastructure for the Biomass Economy

Overview

BioJejak is a B2B traceability and marketplace platform for biomass, organic waste and the bio-based products made from them. It is built for Europe, where biogas plants take manure, crop residues, and food and agro-industrial waste, and it still serves the biomass supply chains of Asia-Pacific. It records every movement of material in a verified chain of custody, then uses that record to let businesses trade with confidence, to return digestate as biofertiliser, and to keep the methane avoided and the carbon saved on the record.

The name says it: jejak means trace or track in Malay and Indonesian. The core belief behind the platform is simple. Europe does not lack biomass. It lacks trust in where that biomass came from, how much of it there is, and whether it arrived at the digester it was meant for. That is the same gap the platform was first built to close in Southeast Asia and Australasia, which remain a second market.

The problem

Europe produces large volumes of organic residue: manure, crop residues, food and agro-industrial waste, and sludges from food processing and wastewater treatment. Much of it is stored, spread, or sent for disposal without a record a plant, a certifier, or a buyer can rely on. Five gaps keep it that way.

• Loads that cannot be reconciled. Contracted and on-farm feedstock leaves a farm and arrives short at the digester, or arrives with no record of where it was loaded. The plant cannot tell where the loss happened, so it cannot stop it.
• Costly and closing disposal routes. Food processors and wastewater operators pay to get rid of sludges and high-strength wastes, and some outlets now refuse them outright.
• No trusted record of feedstock. A biogas, composting or biofertiliser operator buying residue has no reliable way to prove its origin, quantity or quality to auditors, lenders or organic certifiers.
• Fragmented trading and logistics. Buyers and sellers find each other through personal networks, phone calls and spreadsheets. Transport is arranged ad hoc, so supply is unreliable and prices are opaque.
• Carbon and certification value left on the table. Diverting waste from landfill, lagoons or open storage avoids methane, and digestate spread as biofertiliser is the record an organic certifier reads. Without auditable data on what happened to each tonne, neither the emission reduction nor the organic claim can be stood behind.

In Southeast Asia the same gaps appear as fresh fruit bunches missing between the estate and the mill, and as empty fruit bunches, mesocarp fibre, palm kernel shell and palm oil mill effluent with no record of where they went. In Australia and New Zealand they appear as dairy, meat, food-manufacturing and municipal organics trucked to landfill at a rising cost.

The common thread is trust. Each gap is really a missing, verifiable record of who handled what, when and where.

How it works

BioJejak creates a digital twin of each physical batch and follows it from source to final use. Every handover is scanned, timestamped, located and written to an append-only custody ledger, so records can be added to but never quietly changed.

1. Tag at source. When material is harvested or produced, a QR code is attached to the batch and the field user logs block, quantity and weight in the mobile app.
2. Seal and dispatch. The load is weighed at the dispatch point and the truck is linked to the batch with a QR seal.
3. Track in transit. GPS traces the truck's route against an expected corridor. Unplanned stops or detours are flagged in real time.
4. Receive and verify. At the digester, composting plant or mill, the gate scans the seal and records the received weight.
5. Reconcile. The platform compares harvested, dispatched and received quantities for every trip. Matches close automatically; variances are flagged with the route data that explains them.

The same chain continues downstream. When the material becomes biomethane, biofertiliser, compost or fuel, the output inherits the custody record of its inputs. Digestate going back to a farm carries the record organic certification relies on. Buyers get a traceable product, and carbon auditors get the evidence they need.

What it can do

On top of the custody ledger, BioJejak offers five connected services.

• Feedstock assurance. Plants reconcile every load from farm to digester, including their own contracted and on-farm feedstock, and see losses by route, contractor and day. In Southeast Asia, estates and mills use the same reconciliation from block to weighbridge, which cuts fruit theft.
• Feedstock marketplace. Farmers and waste operators list manure, crop residues, and food and agro-industrial waste. In Southeast Asia the listings are empty fruit bunches, palm kernel shell, mesocarp fibre, palm oil mill effluent and rice husk. In Australia and New Zealand they are dairy, abattoir and food-processing sludges, crop residues and food organics. Processors search by type, volume and location and buy with confidence in what they will receive. Where a waste costs money to dispose of, the platform also supports gate-fee deals in which the processor is paid to take it.
• Bio-product marketplace. Processors sell what they make: biofertiliser and compost from digestate, biomethane, bio-CNG, bio-LNG, green methanol, renewable diesel and sustainable aviation fuel, each carrying its upstream custody record.
• Logistics coordination. Transport is booked, tracked and confirmed inside the app, so delivery data and custody data are the same record.
• Carbon MRV. Each batch records its baseline disposal route (landfill, anaerobic lagoon, field dumping, open burning and others) and its actual treatment. These categories align with UNFCCC CDM methodologies AMS-III.F, AMS-III.E and ACM0022, so avoided emissions can be quantified and verified for European biomethane, biofuel and carbon claims, and for the organic record that travels with the digestate. In Southeast Asia the same batch data can be brought to Bursa Carbon Exchange and IDXCarbon. In Australia and New Zealand it can be mapped to Australian Carbon Credit Unit (ACCU) Scheme methods and corporate emissions reporting.

Who it is for

BioJejak is built for businesses, not consumers. Each participant gets something different from the same shared record.

In Europe the typical early customer is a biogas or composting plant that needs feedstock it can stand behind in an audit, and a digestate record the farm and the certifier can both read. Farmers and waste operators are the supply side. In Southeast Asia, estates and mills are the entry point, because fruit reconciliation pays for itself before any residue is sold. In Australia and New Zealand, the entry point is food processors and wastewater operators facing high disposal costs.

Why now

In Europe, demand for renewable gas and fuels, organic certification, and traceability rules for biomass and biofuels are turning residues that were a disposal cost into a feedstock with a price, and turning digestate into a product that has to carry a record. In Southeast Asia, carbon exchanges in Malaysia and Indonesia are creating markets for verified credits, and buyers of palm products face the same traceability requirements. In Australia and New Zealand, landfill levies, organics diversion targets and the ACCU Scheme are putting a price on what happens to organic waste.

All of them reward the same thing: proof. BioJejak's bet is that whoever holds the trusted record of where biomass comes from and where it goes will sit at the centre of the European bioeconomy, and will serve Asia-Pacific with the same record. It starts by knowing what left the farm and what arrived at the digester, and builds from there to a marketplace and a carbon asset.
