Integrated Platform

One continuous operating platform — not a stack of vendors.

Fragmented biomass and carbon projects fail at the seams. Tongao controls and coordinates every physical, agricultural and accounting layer required to convert biomass waste into measurable environmental and commercial value.

Why integration matters

Fragmented vs. integrated.

Fragmented model

Uncertain feedstock supply
Inconsistent production quality
Limited application channels
Weak traceability
Incomplete monitoring
Dependence on external operators
Difficulty scaling carbon projects

Tongao integrated model

Owned feedstock collection network
Regional preprocessing plants
Proprietary carbonisation equipment
In-house biochar & fertiliser production
Direct agricultural application
Circular agriculture & food distribution
Digital MRV & traceability across all layers
International carbon certification & offtake

Value flow

Value and data circulate — not one-way, but a closed loop.

Biomass sourcing

Agricultural, forestry, bamboo and landscaping residues aggregated across regional collection networks.

Collection & preprocessing

Seven regional preprocessing plants in Zhejiang handle sorting, drying, sizing and quality control.

Carbonisation

Centralised and distributed carbonisation systems produce biochar and pyrolysis gas with self-sustaining thermal loops.

Clean-energy recovery

Recovered heat and combustible gas feed steam, hot water, hot-air drying and on-site power.

Biochar & product formulation

Biochar-based fertilisers, growing substrates, feed additives, construction and battery-grade materials.

Soil & agricultural application

Crop-specific programmes for rice, grapes, tea and vegetables with soil restoration and low-carbon farming.

Digital MRV & traceability

Data pipelines from feedstock, production and field application feed independent verification.

Carbon certification

Project development, certification and issuance with Puro.earth and Carbon Standards International.

Carbon-credit commercialisation

Offtake agreements with corporate buyers and low-carbon products routed to global markets.

Integrated project development for governments, industrial parks and investors.

AOD (Agricultural Origination & Development) delivers the full Tongao value chain as an EPC + O engagement — from feedstock, production and equipment through carbon certification, low-carbon products and supply-chain finance.
