✦ In brief

In a waste department, a Blue Lemon Agent agent absorbs the repetitive work — replies to residents, billing of the waste charge, tracking bin requests and reports — and passes on what needs to go to the operations team. It runs on local inference or is hosted in France on a resource dedicated to and isolated for each authority: addresses, household composition and billing data are never exposed to a foreign service, architecture designed to reduce exposure to extraterritorial legislation, location alone not being enough to guarantee immunity. The public officer approves every invoice and every letter; the time won back goes to the service given to residents. Live within a few weeks. Your public-sector staff write to it from Microsoft Teams, Slack or their email, and your users reach it on WhatsApp Business, the website chat or email — with no account to create and nothing to install. Reaching the administration from the tool people already have means less non-take-up of rights and equal access to the service. These connections are included in every plan, at no extra cost, within the number of connections your level includes.

The context

Why AI matters to waste departments — and why they hesitate

Between collection, recycling centres, the pay-as-you-throw charge and complaints, the waste department is one of the busiest in the authority. Requests arrive on every channel, and the billing demands flawless rigour on personal data: addresses, household composition, bin lifts.

! The issue

The teams are caught between residents who expect quick answers — a bin not collected, a bin size, the calendar, the rate — and a pay-as-you-throw charge whose billing is ever finer (lifts, drop-offs, anomalies). Yet most consumer AI tools amount to entrusting addresses, household composition and billing data to a third party, often hosted outside Europe and subject to the Cloud Act.

Our answer

For public data, AI is only of interest if it is sovereign and confidential by design. Local inference or an isolated resource hosted in France, systematic human oversight, decisions reserved to the public officer: the pricing parameters stay set by the authority, and every invoice and every letter is approved before issue. The aim is not to replace the teams, but to give them back time for operations and for residents.

The decisive point

Protecting the public's data: sovereignty & compliance

A waste department handles personal data on a large scale: addresses, households, billing. Here is how the architecture of our agents protects it, authority by authority.

Local inference

The agent can run on a machine belonging to the authority: no data leaves the network, nothing passes through a cloud.

Hosting in France

Otherwise, a dedicated and isolated resource, hosted in France under French law — the public's data: processing and access within the European Union targeted by the architecture.

Reduced extraterritorial exposure

For residents' data, the architecture aims to reduce exposure to the Cloud Act and FISA 702; being located in France or in the European Union does not, on its own, guarantee immunity.

One isolated resource per authority

No pooling of data: an environment strictly dedicated to your authority, guaranteeing the continuity of the public service.

Encryption & controlled access

Encryption in transit and at rest, role-based access (RBAC), strong authentication and logging.

AI Act: governed deployment

The agent is strictly in support; no invoice is issued automatically; traceability and human oversight from end to end.

What depends on the architecture chosen These points are not general guarantees: they are settled deployment by deployment, in the quotation.

  • The applicable location is that of the architecture set out in the quotation and verified before commissioning.
  • Local execution is announced only for the configuration explicitly described and accepted in the quotation.
  • The applicable isolation depends on the deployment mode set out in the quotation; no dedicated isolation is presumed.
  • The encryption mechanisms in transit and at rest, their components and key management are those documented for the architecture chosen.
  • Roles and permissions are configured and accepted for the identities and systems actually connected.
  • The events logged, their content, their retention period and who may access them are defined for the deployment chosen.
For the most sensitive data, SecNumCloud and HDS options are available depending on your requirements. A single architecture is designed to answer both the GDPR and extraterritorial exposure. Designed for deployment in line with the GDPR and the AI Act, after the processing, roles and context-specific risks have been assessed.

A scripted demonstration. These exchanges show how the agent behaves — its sources, its refusals, what it leaves to your teams. Nothing is sent from this page, no model is queried here, and the matters named are fictional. That is precisely what we promise your data.
The behaviours shown here — monitoring, automation rules, routing and reminders — are configured with you during deployment, from your tools, your rules and your thresholds.
The architecture points named in these exchanges — location, local execution, isolation, encryption, role-based access, logging — are not a guarantee attached to the demonstration: they are those of the architecture set out in your quotation, and verified before commissioning.

The public body in this demonstration

Fictional public body

Trois-Vallons Community of Communes — waste authority covering 17 municipalities (fictional authority)

Sector
In-house collection and charge authority for a community of communes of 26,800 inhabitants — kerbside collection of residual waste and packaging, 2 civic amenity sites, 46 bring banks, pay-as-you-throw household waste charge since 1 January 2024
Headcount
34 staff in the authority, 8 of them on resident relations and charging — 6 case officers, one head of service and one apprentice; the other 26 are on collection rounds and civic amenity sites, and the agent does not touch that side
Public served
12,400 households across 17 municipalities and 5 collection sectors — 21,600 enquiries a year: 12,900 phone calls, 5,400 emails, 2,100 counter visits, 1,200 website forms
Order of magnitude
2 billing campaigns a year, 24,800 invoices issued; 3,940 collection complaints, 2,180 bin allocation or exchange requests, 1,460 civic amenity site enquiries, 6,300 charge letters; 3,620 tonnes of residual household waste collected in 2025, i.e. 135 kg per inhabitant since the move to pay-as-you-throw
Tools already in place
Waste management software (charge-payer file, bin chips, lift log), billing software, published collection calendar, service mailbox and Microsoft Teams — the agent reads them, nothing is replaced and nothing is migrated
Who decides what
The head of the waste service approves every letter and every billing file before it goes out; tariffs and the bin allocation grid are set by resolution of the community council; ex gratia waivers rest with the chair
Room for improvement
4,128 calls out of 12,900 ring unanswered in the week following each billing run — 32%; an email waits 9 days on average; preparing a campaign ties up all 6 case officers for 11 working days; and the charge-payer file had never been reconciled against the lift log — 18 anomalies were sitting undisturbed in the north sector alone

At Trois-Vallons, eight staff carry resident relations and the waste charge for 12,400 households, with two annual peaks around the billing campaigns. The most repetitive questions — bin not collected, bin size, site opening hours, calendar — take up three quarters of the flow, and it is the cases that deserve a human that queue up behind them. The exchanges below cover a full year, from the first reconciliation of the file to the report presented to the community council. The agent is hosted in France on an isolated resource, reads the waste management software and the lift log without ever writing to them, and no invoice goes out without the head of service's approval.

This public body, its figures and the exchanges that follow were invented for the demonstration. They illustrate a common situation; they describe no real service.

Waste & charge assistant · hosted in France
I have reread your 21,600 enquiries for the year and reconciled, household by household, your charge-payer file against the lift log — the reconciliation the campaign never leaves time for.
What the count says: 12 topics cover 16,740 enquiries out of 21,600, more than three in four. Bin not collected, bin size and exchange, collection calendar, opening hours and access to the two civic amenity sites, what goes in the yellow bin, bulky waste, composter, moving house, change of occupier, amount of the charge, payment methods, site access card. The 12 reference answers are written, sourced on your collection by-law and on the resolution of 27 November 2025, and dated — they are waiting for you.
What the three items you can check against your own logs are worth:
· A collection complaint takes 12 minutes end to end, 60% of which goes on finding the sector, the round day and on drafting — 7 minutes 12.
· A charge letter takes 25 minutes, 40% of it on the drafting itself — 10 minutes.
· Preparing a billing campaign is 100% manual work: 11 working days for your 6 case officers, i.e. 462 hours per campaign.
And the gap the reconciliation brought out, in the north sector alone — 1,240 households: 18 anomalies, never seen because nobody ever had the 11 days to look. 7 lifts with no active contract, 5 duplicate chips, 3 unreadable chips, 3 standing charges billed to an occupier who had left. In euros: €612.00 you did not bill and €966.00 billed wrongly or to the wrong payer.
The next step, and it takes twenty minutes: you reread the 18 lines and tell me, for each one, the action you want. The head of service settles the version, and the 18 come out of the file before the next campaign. waste-service-flow_21600-enquiries-12-topics.pdf16,740 enquiries across 12 topics, the three items costed, 3,371 hours identified
⛓ Sourced · 12 months of enquiry log, charge-payer file, lift log, tariff resolution of 27 November 2025
18 anomalies in a single sector — what does that mean across 12,400 households? And above all: how do we avoid doing it all again next year?
Across the 12,400 households, the same reconciliation rule brings out 180 per half-year — 360 over the year. In euros: roughly €6,120 not billed and €9,660 billed wrongly per campaign, i.e. €12,240 and €19,320 over the year. The amount is not the main point: each of those 360 lines is a resident complaint waiting to happen, and a complaint costs 12 minutes plus the trust.
What I did on top, and what the campaign never leaves time for: I wrote four control rules, in the language of your own by-law, and ran them over your last 24 months of lifts. For each one I give you the number of alerts it would have produced, the share confirmed after examination, and what it would have let through — you choose on figures, not on a hunch:
· Rule A — a chip read when no contract is active at the address on the day of the lift: 412 alerts over 24 months, 389 confirmed — 94.4%. The other 23 are contracts entered late, which is fixed at data entry.
· Rule B — the same chip read twice less than two hours apart on two different rounds: 196 alerts, 183 confirmed — 93.3%.
· Rule C — a standing charge billed to a payer whose departure the service has recorded: 148 alerts, 148 confirmed — 100%.
Total: 756 alerts over 24 months, 720 confirmed — 360 a year, exactly the figure from the reconciliation.
And here is what those three rules let through, because you need to know it before you sign: 68 lifts recorded at the flat rate for want of a readable chip fall under none of the three. So I wrote rule D — a lift recorded with no readable bin identifier — and ran it over the same 24 months: 68 alerts, 61 confirmed. The four rules together cover 781 of the 824 alerts raised over the period — 94.8%.
Bringing a rule into force stays with the service: a rule only goes live once approved by the head of service, and that is precisely what makes it defensible against a resident who disputes their invoice. I save you the writing and the measuring; the decision takes twenty minutes instead of a committee. charge-anomalies_4-rules-tested-over-24-months.pdfThe 18 north-sector anomalies in detail, 4 rules tested, 781 of 824 alerts confirmed
⛓ Sourced · 24 months of lift log (1,187,400 lifts), charge-payer file, collection by-law
We bill 12,400 households. Addresses, household composition, bank details: where does that data go?
Nowhere outside your walls, and that is verifiable rather than promised.
Where I run: on an isolated resource hosted in France, under French law, dedicated to Trois-Vallons and to nobody else — or on a machine in your own depot if you prefer local inference, in which case nothing even leaves the network. No resident data is passed to a foreign service: exposure to the Cloud Act and FISA 702 is reduced accordingly, without location alone ruling it out — it is documented for the configuration chosen.
What I read, and what I cannot reach: I have read-only access to the charge-payer file, the lift log and the collection calendar. I have no write access to the billing software: I produce files and draft letters, your case officer imports them. Bank details are not open to me at all — I have no use for them in preparing an invoice, and article 5.1.c GDPR asks precisely that only what serves the purpose be exposed. Access is withdrawn with a word, and withdrawal takes effect within the second.
What you can show your data protection officer: every read is logged with its date, its reason and the line concerned; every output carries the sources it was drawn from; and the record of processing activities is already written, legal basis by legal basis — public interest task for the charge, article 6.1.e.
The next step I propose: a thirty-minute quarterly review in which I set out the access rights actually used and those that served no purpose — an unused right of access is a right to close, and I bring you the list rather than asking you for it. sovereign-framework_hosting-access-traceability.pdfWhere the data lives, who reads what, what is withdrawn with a word

Frequently asked questions

Your questions, our answers

Does the agent manage collection on the ground?
No: strictly administrative (resident relations, billing, tracking requests). Operations stay run by the teams.
Where is the data processed?
In France, on a resource isolated for each authority. GDPR: governed deployment.
Does the agent handle the pay-as-you-throw charge?
Yes: it tracks lifts and drop-offs and prepares the billing, but the pricing parameters stay set by the authority.
Does it integrate with our waste management software?
Yes: through secure integrations defined at the design stage.
Does the agent state that it is an artificial intelligence?
Yes, from the very first interaction, and this is not a configuration option: since 2 August 2026, Article 50(1) of the European AI Regulation requires that any person interacting with an AI system be informed, unless this is obvious. The announcement is built into the greeting, in the other party’s language, and they can ask for a human at any time.
How long does it take to deploy an agent?
A few weeks as a rule, after a free audit that identifies the most useful use case, then a phase of design, integration and testing before going live and handing over to the teams.
Do we need a technical team in-house?
No. The agent is designed, installed and operated by us: supervision, updates and maintenance are included. Your teams concentrate on their work.
Do we have to change software?
No. The agent complements your existing tools (waste management, billing), with no migration imposed. We adapt the integration to your authority's environment.
Which tools can users use to reach the agent?
The ones they already have. The agent answers on WhatsApp Business, the website chat and email: users have no account to create and no application to install. This is a lever for access to the service — WhatsApp and the telephone reach people an online form never does, which reduces the non-take-up of rights and serves equal access. Internally, your public-sector staff talk to the agent from Microsoft Teams, Slack or their email, without switching tools. Oversight runs from a web dashboard. These connectors rely on open standards, including the MCP protocol; they are included in every plan, at no extra cost, within the number of connections your level includes. Only the fees charged by the platforms themselves — WhatsApp Business bills per conversation, and the gateway bills the text messages sent — are passed on at actual cost, with no margin, outside the subscription.
Can the agent notify users by text message?
Yes, as an option — and it is the channel that reaches the people the others never do. A text message arrives on an ordinary phone: no email address, no account, no app, no data plan and no smartphone. Announcing by text message a collection moved, a recycling centre closed or a bin to put out the evening before a public holiday means fewer entitlements going unclaimed and more equal access to the service. It is an outbound notification channel, not a conversation channel: users do not write to the agent there — they reach you on WhatsApp Business, the website chat or email. The message announces without detailing — never the reason, never the detail of the situation — and never contains a payment link, a login or a password: users reach the service the way they usually do. Delivery goes through a gateway established in the European Union; the messages sent are passed on at actual cost, with no margin, and the channel itself is an optional module, set out on the pricing page.
