Claims, one by one

The text below is copied verbatim from the published record. Each claim names the source dossiers that carry it; caveats stay attached to the claim they qualify.

Claim 1 clm-344a378c9b9a1a8f quantitative
Since 2000, Envac's underground pneumatic network has sucked household waste from inlets across Hammarby Sjöstad to central stations
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Envac's project page gives the launch year as 2000 and states that the systems "have been collecting waste at certain locations and across three fractions including general waste, food waste and paper and street litter since the first system became operational in 2000". The same page counts "~770 waste inlets" and "~12,700 apartments" connected, with a designed capacity of 20 tonnes a day.
Caveat
Not all of the district's waste travels to a central station. Envac's page describes "three stationary systems that serve Norra Hammarbyhamnen, Hammarby Gård and Henriksdal/Lugnet and two mobile systems serving Sickla Kaj, Sickla Udde and Sickla Kanal" — in the mobile sub-systems the waste is held in sealed underground tanks and emptied by a vacuum truck rather than piped to a plant. The same sentence calls this "six Envac systems" while listing five.

Claim 2 clm-941e86f2f841c85d descriptive
replacing collection trucks
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The trade magazine Elinstallatören, reporting from inside the district's largest pneumatic plant, writes that the system "serves 3,000 households and means that one large lorry replaces many refuse lorries in the area" ("Sopsugen servar 3 000 hushåll och gör att en stor lastbil ersätter många sopbilar i området"), and explains the arrangement: "instead of waste collection at every building, the containers at the pneumatic central station are picked up once every other day by one large lorry".
Caveat
Trucks are reduced rather than removed: one large lorry still collects the containers from the central station every second day. Envac's own figure is a 60 per cent reduction in on-site collection vehicles, not their elimination.

Claim 3 clm-048164b5633f439e descriptive
Local property-owner associations, not the city, own and pay for it
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The western sub-system's association states that "the property owner owns it jointly with the other property owners in the area and it is looked after by a joint-facility association", and that "the association has an operating agreement with Envac, which runs the plant". Its members' page shows the funding: "Every year the property owners pay an annual fee to the association", covering electricity, service and monitoring, with larger renewals financed by member contributions. Stockholm's municipal utility lists only two districts it runs — "We are responsible for operating the pneumatic waste systems in Norra Djurgårdsstaden and in Hagastaden" — and Hammarby Sjöstad is not among them. Envac's project page, however, names "The City of Stockholm" as the client for the installation, which describes who commissioned the original build rather than who owns and finances the network today.
Caveat
Only the western association publishes its ownership and finances; the owners of the district's other pneumatic sub-systems are not documented in the sources listed here. The municipal utility's page is evidence by omission — it names the districts it does run, not the ones it does not.

Claim 4 clm-7386af2d190875b3 quantitative
100–120 blockages a year from wrongly binned items cost each incident 1,500–3,000 SEK to clear
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The association writes: "We have about 100-120 stoppages a year caused by unsuitable goods being thrown down, such as pizza boxes, bag-in-box wine packaging, polystyrene, online-shopping cartons, ring binders, frying pans and the like", and: "Clearing it costs about 1500 – 3000 kr including VAT each time."
Caveat
Both figures describe the western sub-system alone — roughly 3,000 of the district's some 12,700 connected apartments — not the whole of Hammarby Sjöstad. The cost range is stated inclusive of VAT.

Claim 5 clm-17d38449f42b971e descriptive
residents have lobbied Stockholm to take it over
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Sjöstadsföreningen, the district's umbrella residents' association, reported after a members' meeting on 6 May 2015 that one of two pressing questions was "that the municipality takes over responsibility for the pneumatic waste plants, which the association has demanded", and listed what it had done: "The association has demanded that the City of Stockholm take over, written to the political parties, called on environment commissioner Katarina Luhr and shown her how it works — and does not work — in Sjöstaden."
Caveat
No claim-specific caveat recorded

Claim 6 clm-b7846ea3f090a073 quantitative
Envac says the network cut on-site collection vehicles by about 60%
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Under "The Result", Envac's project page lists: "Beaten its waste collection vehicle reduction target – Hammarby's Envac system has since reduced on site collection vehicles by 60%." The same list also claims the district "Reduced the total amount of recyclable and waste material by 20% in weight."
Caveat
This is the supplier's own promotional project page. It gives no baseline, no date and no measurement method: the 60 per cent is presented as having beaten an unstated internal reduction target, and no figure for the vehicles before or after is published. No independent evaluation of the number is listed here.

Claim 7 clm-16b8005fdb8c40b6 quantitative
the western sub-system's property-owner association reports 100–120 unplanned stoppages a year, mostly from mis-sorted items, at 1,500–3,000 SEK per repair
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Sjöstadens Västra Sopsug Samfällighetsförening publishes both figures on its own resident information page: "We have about 100-120 stoppages a year caused by unsuitable goods being thrown down", and "Clearing it costs about 1500 – 3000 kr including VAT each time." The same page names Envac as the contractor running the plant under an operating agreement with the association.
Caveat
The association owns and finances the system, so this is the owner's own operating figure rather than an outside assessment — it is independent of the supplier's marketing, not of the system. The page attributes the 100–120 stoppages to unsuitable items outright rather than saying most of them are so caused, and it publishes no breakdown of total downtime by cause.

Claim 8 clm-d5e3fdf202eb2a19 descriptive
A pneumatic network removes trucks from the street

lesson · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Elinstallatören describes the change in collection pattern: "Instead of waste collection at every building, the containers at the pneumatic central station are picked up once every other day by one large lorry", and quotes Envac's production manager saying pneumatic systems are popular in districts wanting a strong sustainability profile "because traffic decreases".
Caveat
The trucks move rather than disappear: collection is concentrated at the central station instead of at every entrance, and one large lorry still serves it every second day.

In Hammarby Sjöstad that's private property associations, not the city
Published field
lesson · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The western association states that the plant is owned jointly by the property owners and looked after by a joint-facility association, which holds the operating contract with Envac. Stockholm Vatten och Avfall, the municipal utility, says of itself: "We are responsible for operating the pneumatic waste systems in Norra Djurgårdsstaden and in Hagastaden", and explains the rule behind that scope — the city council decided the utility should run stationary pneumatic plants "built in development areas on the city's land". Hammarby Sjöstad appears nowhere on that page.
Caveat
The municipal utility's page establishes this by omission rather than by statement: it lists the districts it operates and does not mention Hammarby Sjöstad at all.

Claim 10 clm-623be57bd8fc8f1a descriptive
the leading cause of downtime is residents mis-sorting waste, not equipment failure
Published field
lesson · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The association's resident page attributes its stoppages to what goes into the inlets, not to the machinery: "We have about 100-120 stoppages a year caused by unsuitable goods being thrown down, such as pizza boxes, bag-in-box wine packaging, polystyrene, online-shopping cartons, ring binders, frying pans and the like". It frames the residents' own part as the remedy: "Your contribution is to throw the right things down the chutes to avoid unnecessary stoppages."
Caveat
The association names no competing cause and publishes no breakdown of total downtime, so "leading cause" is a reading of the only figure it gives rather than a ranking it states. The figure covers the western sub-system only.

Claim 11 clm-981541769cd43918 quantitative
Since at least 2015 residents have pushed Stockholm to take the system over
Published field
lesson · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Sjöstadsföreningen's news item of 10 June 2015, headlined "Keep pressing for municipalisation of the pneumatic waste system!", records a members' meeting on 6 May at which the board was urged to keep going, and states that "the association has demanded that the City of Stockholm take over, written to the political parties, called on environment commissioner Katarina Luhr and shown her how it works — and does not work — in Sjöstaden." The same item says the older mobile parts of the system serve about 3,000 apartments.
Caveat
The 2015 item is the only dated campaign document among the sources listed here, so it fixes the start of the pressure but not how long it continued.

Claim 12 clm-b470f0b90d6675aa descriptive

Published field
lesson · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The western association still describes the plant as jointly owned by the property owners and run by Envac under a contract with the association, and its members' page still bills the owners an annual fee and plans their share of renewals out to 2051 — the arrangement a municipal takeover would end. Stockholm Vatten och Avfall names only Norra Djurgårdsstaden and Hagastaden as the pneumatic systems it operates.
Caveat
No source listed here records a decision by the city, so this rests on the system still being in private hands and on the municipal utility's own list of the plants it runs, not on a documented refusal.

  • Publisher names and source languages have not yet been classified; domains are recorded without guessing.
  • Existing source notes are descriptive locators, not page- or paragraph-exact citations.
  • A missing archive, publication date or content hash is shown as null rather than inferred.
  • The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
