21.40 kg CO₂
per tonne.

Per tonne of food waste, digested on-site. Measured automatically at the machine — not estimated. Outperforms dehydrators by a factor of 16 and landfill by a factor of 138.

Most desirable on-site
treatment after donation.

A 2022 study by the Faculty of Geotechnical Engineering ranked ten food-waste management methods by carbon footprint. Griffon’s aerobic digestion is identified as the most desirable on-site treatment after donation, with the lowest processing footprint of the devices tested. The research was not commissioned by Griffon; the device was selected by the academic team as a representative of the aerobic-digestion category.

What 21.40 kg per tonne means

A real-world example.

Croatian restaurants and catering establishments generated 15,072 tonnes of food waste in 2021. Sent to landfill without gas capture, that waste would have emitted between 28,637 and 43,709 tonnes of CO₂ equivalent — depending on the study used for the carbon factor.

Processed entirely by Griffon, the same volume would have emitted 318 tonnes of CO₂. That is the equivalent of taking between 6,170 and 9,418 passenger cars off the road for a year — or planting 473,000 to 723,000 tree seedlings growing for ten years.

Measured at the source

Every kilogram.
Logged automatically.

01
Built-in scales

Every kilogram is weighed automatically at the point of input. No manual data entry. No hauler estimates. The scale is the data source — primary data per the CSRD definition.

02
Automatic logging

Daily, monthly and annual food-waste mass logs, exported on demand (CSV, PDF, JSON). This measured mass is the primary data your ESG figures are calculated from — the machine does not estimate or self-certify.

03
CO₂ tracking from primary data

Transport trips eliminated, tonnes diverted from landfill, CO₂ avoided — all derived from primary data using the carbon factors validated by the 2022 University of Zagreb research.

04
Reporting-ready data

Structured mass data your ESG team converts into Scope 1 and Scope 3 disclosures and food-waste reduction reporting — primary-data evidence, not estimates.

CSRD context

Why primary data matters now.

For organisations that report under the EU Corporate Sustainability Reporting Directive, estimates and industry averages no longer satisfy auditors. They require primary data — weighed, time-stamped and traceable to the source.

Griffon is positioned as an audit-grade primary data source for Scope 1 and Scope 3 emissions tied to food-waste handling. Each kilogram contributes a documented data point to your sustainability statement. Following the 2025 Omnibus simplification, mandatory CSRD reporting now applies to larger groups (over 1,000 employees and €450M turnover); for every other operator, the same primary data supports voluntary ESG reporting and the EU’s binding 2030 food-waste reduction targets.

This is what
your audit team gets.

Built from the machine’s measured mass data: an anonymisable, audit-grade report covering food-waste mass diverted at source and the avoided CO₂ calculated from it. Aligned with ESRS E1 (Climate) and ESRS E5 (Circular economy) under CSRD Directive (EU) 2022/2464. ISO 14064-1 and GHG Protocol Scope 1/2/3 calculation framework.

What’s inside the report

Five sections.
One source of truth.

01
Executive summary

Three primary numbers: tonnes processed, net CO₂e avoided, pickups eliminated. Plus operating uptime and labour-handling hours saved.

02
Methodology & scope

Load-cell calibration trail, PLC continuous logging, emission factor sources (JRC, EEA). Inside-scope vs outside-scope clearly delineated to prevent double-counting against the property’s own utility disclosure.

03
Period data · ESRS E1

Monthly mass breakdown with calculated CO₂e impact. Net carbon balance: emissions avoided minus unit’s operational electricity footprint.

04
Circular economy · ESRS E5

Material circularity rate, waste-to-landfill ratio, mass diverted at source. Resource flow accounting per ESRS E5-5 reporting line.

05
Verification & statement

Load cell calibration verification, PLC data integrity check, continuity of operation log, emission factor source review. Formal statement of preparation per ISO 14064-1.

06
Independent assurance

Third-party assurance available upon request. Strategic ESG narrative, materiality assessment, and water/electricity disclosure remain the client reporting team’s responsibility.

Every gram, logged.

No spreadsheets. No estimates. Primary data, captured at the machine, ready for audit. Full sample ESG report and the University of Zagreb research available on request.
