Octo for the port environment

Environmental performance is measured. Octo helps organize the evidence.

ANTAQ's Environmental Performance Index (IDA) is currently established by ANTAQ Resolution 123 of December 17, 2024, which revoked Resolution 2.650/2012; ANTAQ describes the indicators weighted by the AHP method. Law 12.305/2010 subjects those responsible for terminals to the solid waste management plan, and the IMO publishes consolidated guidance for providers and users of ship waste reception facilities. Octo can help your team gather and keep current the evidence each requirement calls for.

What Octo does for the environment.

Four possible deliverables. Technical responsibility remains with the environmental team.

Evidence per indicator

Can build the list of IDA indicators with the evidence your team keeps for each one, where it is and when it was updated.

Deliverable: evidence table per indicator

PGRS with the minimum content

Can organize the waste assessment, with origin, volume and characterization, and check whether the plan covers the minimum content of art. 21 of Law 12.305/2010.

Deliverable: minimum content checklist with what is missing

Reception of ship waste

Can organize ship waste reception records in light of the IMO's consolidated guidance for providers and users.

Deliverable: organized record for review

Changes tracked

Can follow the IDA structure and indicators page and alert the team when it changes.

Deliverable: notice of what changed

Eight arms, one evidence table.

The same Octo cycle, applied to this topic. Each arm has a narrow role; the people who approve and sign are on your team.

Discovery
Lists the requirements

Which IDA indicators, which PGRS items and which waste records apply to your facility.
Data
Links requirement and evidence

Each requirement linked to the document that proves it, with location and date.
Security
Respects the document

Licenses and technical reports belong to the company. Octo works only in the approved environment.
Architecture
Picks the format

Spreadsheet, database or organized folder, matching how the team already works.
Development
Builds the table

Requirements, evidence, dates and outstanding items.
Review
Checks with the person in charge

The professional of record reviews the table before it counts.
Release
Delivers with your OK

The table goes wherever the team says.
Documentation
Records the version

Which version of the IDA structure and the IMO guidance was used.

Octo does not sign environmental plans or answer for the index. The professional of record and the environmental team remain in charge.

Each requirement, its basis.

Environmental requirements with a published source. The official text remains the reference.

Requirement	Basis	What it requires
Environmental Performance Index	ANTAQ Resolution 123/2024, of December 17, 2024	Establishes the IDA; Resolution 2.650/2012 is revoked
IDA structure	ANTAQ, structure and indicators	38 indicators, 4 categories and 14 global indicators (accessed October 28, 2026)
Terminal PGRS	Law 12.305/2010, art. 20, IV	Those responsible for terminals are subject to the plan
Minimum PGRS content	Law 12.305/2010, art. 21	Assessment with origin, volume and characterization of the waste
Reception of ship waste	IMO, MEPC.1/Circ.834/Rev.1	Consolidated guidance for providers and users

From request to routine.

Three steps. Each one only makes sense once the previous one has shown results on your team.

A proposal, not a promise

What Octo does and what stays with you.

Octo prepares everything, but does not sign. The document of record stays with whoever is accountable for it.

Octo prepares

Gathers, calculates, organizes and produces the documents: spreadsheets, reports, dashboards and drafts.

Deliverable: material ready for review

Your team reviews

The licensed professional reviews what Octo delivered before signing. If something doesn't add up, it goes back to Octo with the correction.

Step: review by whoever signs

Who signs

Octo does not sign. Designs, technical reports, ART/RRT, accountability reports and any official document are still signed by the licensed professional at the company or agency: here, the professional of record and the port authority.

Signature: professional of record and port authority

The right evidence in the right place.

The assessment starts with the environmental documents your team already has, without changing anything. You get a proposal for what can be organized and decide with it in hand.
