  "markdown": "## What decides the footprint of a capsule coffee\n\nA capsule is a sealed single dose of ground coffee made for one machine. The entry on coffee capsules describes the systems. Its environmental cost is usually judged by a life-cycle assessment (LCA). An LCA adds up the impacts of a product from raw material to waste.<sup><a href=\"#src-s1\">1</a></sup>\n\nEvery LCA refers its results to a functional unit, the “quantified performance of a product system for use as a reference unit”.<sup><a href=\"#src-s2\">2</a></sup> For coffee this may be a cup of a set volume or a mass of coffee.<sup><a href=\"#src-s1\">1</a></sup> The carbon footprint entry explains the method and gives the footprint of coffee as a whole.\n\nThree things weigh on a capsule cup:\n\n- **The coffee itself.** In a 2018 study, the amount of dry coffee used and the energy to brew it were the two largest contributors in every category.<sup><a href=\"#src-s3\">3</a></sup> According to a 2023 university report, coffee grounds were the largest source of greenhouse gases in single-serve use.<sup><a href=\"#src-s12\">12</a></sup>\n- **The packaging.** A 2024 review of coffee LCAs found packaging made up a median 9–18% of the footprint. The higher figure applied to single-serve pods and capsules, with great uncertainty.<sup><a href=\"#src-s1\">1</a></sup>\n- **The machine.** A 2011 German study linked the high impacts of capsule and fully automatic machines to power use, especially in sleep and standby mode.<sup><a href=\"#src-s4\">4</a></sup>\n\nCapsules use a fixed, small dose. A 2009 study assumed 6.5 g of coffee per capsule cup and 13.5 g per drip filter cup, including 33% losses.<sup><a href=\"#src-s5\">5</a></sup> Coffee brewed but not drunk can therefore shift the comparison in favour of capsules.<sup><a href=\"#src-s3\">3</a>,<a href=\"#src-s5\">5</a></sup> Researchers at the Université du Québec à Chicoutimi made the same point in a 2023 article for a general audience.<sup><a href=\"#src-s22\">22</a>,<a href=\"#src-s3\">3</a></sup>\n\n## What life-cycle studies found\n\nThe studies do not agree on whether capsules come out better or worse than other methods. Their results depend on the dose, the share of coffee wasted, the machine and what each study counts.<sup><a href=\"#src-s1\">1</a>,<a href=\"#src-s3\">3</a>,<a href=\"#src-s4\">4</a></sup>\n\n- **Pod style lowest.** A 2018 study compared drip filter, French press and pod-style brewing. Drip filter had the greatest impact in all categories; pod style had the least in six.<sup><a href=\"#src-s3\">3</a></sup>\n- **Capsules highest.** In the 2011 German study, French press and drip filter machines did best, capsule and fully automatic machines worst.<sup><a href=\"#src-s4\">4</a></sup>\n- **Capsule in between.** A 2009 study found soluble coffee lower than capsule espresso, and drip filter highest per cup, water use included.<sup><a href=\"#src-s5\">5</a></sup> The energy used for capsule packaging was comparable in size to that of the use phase.<sup><a href=\"#src-s5\">5</a></sup>\n- **Paper pods lowest.** A 2020 study by Brazilian researchers found a paper-sachet pod lowest among single-serve options, at 14.3 g CO₂e per 50 mL.<sup><a href=\"#src-s7\">7</a></sup> Among single-serve options, plastic capsules with an aluminium top seal used the most energy and water and made the most waste.<sup><a href=\"#src-s7\">7</a></sup>\n- **Bag coffee lower than capsules.** A 2025 study counted only use and disposal. Coffee from a multilayer bag came to 8.2 g CO₂e per cup, a polypropylene (PP) capsule to 41 g.<sup><a href=\"#src-s8\">8</a></sup>\n\n<figure>\n<div data-figure=\"capsules-and-the-environment-per-cup\"></div>\n<figcaption>Greenhouse gas emissions per cup in three studies (g CO₂e, carbon dioxide equivalent). 2021: 40 mL cup in Italy, coffee itself left out.<sup><a href=\"#src-s6\">6</a></sup> 2020: 50 mL, from cultivation to waste.<sup><a href=\"#src-s7\">7</a></sup> 2025: use and disposal phases only.<sup><a href=\"#src-s8\">8</a></sup> Compare within one study; boundaries differ between them.</figcaption>\n</figure>\n\nA literature review of 2021 notes that some capsule LCAs “were funded by stakeholders directly affected by the coffee market”.<sup><a href=\"#src-s9\">9</a></sup> The Deep dive gives each study’s functional unit, boundary and electricity mix, and who commissioned it where the source says so.\n\n## What happens to used capsules\n\nCapsules are made of aluminium, plastics such as PP, laminates, compostable polymers or paper.<sup><a href=\"#src-s8\">8</a>,<a href=\"#src-s9\">9</a></sup> After brewing, each one holds wet coffee grounds. A 2021 review names the separation of capsule parts and grounds as one of the main challenges for recovery.<sup><a href=\"#src-s9\">9</a></sup>\n\n- **Aluminium.** The Swiss Federal Office for the Environment (FOEN, German BAFU) states that shops and many municipal collection points take back coffee capsules.<sup><a href=\"#src-s17\">17</a></sup> According to the FOEN, packaging made from recycled aluminium needs 95% less energy than packaging from new metal.<sup><a href=\"#src-s17\">17</a></sup>\n- **Laminates.** A 2021 Italian study assumed that its plastic–aluminium laminated capsule was not separated into its materials but went to landfill.<sup><a href=\"#src-s6\">6</a></sup>\n- **Compostable.** In a 2020 trial at a Dutch composting plant, used compostable capsules were still mostly present after two cycles of about 11 days.<sup><a href=\"#src-s11\">11</a></sup> The authors still did not expect them to add significantly to the residue the plant discards.<sup><a href=\"#src-s11\">11</a></sup>\n\nNo official or peer-reviewed figure for how many capsules are collected or recycled, in Switzerland or elsewhere, was found when the entry was checked. The FOEN page gives none.<sup><a href=\"#src-s17\">17</a></sup>\n\n## EU rules for capsules and pads\n\nThis section describes what the legal texts and the Commission’s guidance say, as of October 2026. It is not legal advice. The packaging entry covers the EU Packaging and Packaging Waste Regulation (PPWR) as a whole.\n\nThe PPWR, Regulation (EU) 2025/40, counts single-serve coffee units as packaging, because they are thrown away with the used coffee.<sup><a href=\"#src-s13\">13</a>,<a href=\"#src-s14\">14</a></sup> The regulation dates from 19 December 2024.<sup><a href=\"#src-s13\">13</a></sup> It entered into force on 11 February 2025 and applies from 12 August 2026.<sup><a href=\"#src-s14\">14</a>,<a href=\"#src-s16\">16</a></sup> It treats two kinds of unit differently.<sup><a href=\"#src-s14\">14</a></sup>\n\n- **Pads and soft units.** Permeable coffee bags and soft single-serve units must be compatible with industrial composting by 12 February 2028.<sup><a href=\"#src-s14\">14</a>,<a href=\"#src-s15\">15</a></sup> The Commission reads this as covering any material, paper included.<sup><a href=\"#src-s14\">14</a></sup>\n- **Capsules.** Non-permeable units for a machine fall under the general rule that all packaging must be recyclable.<sup><a href=\"#src-s14\">14</a></sup> Member States may instead require compostable capsules made of material other than metal.<sup><a href=\"#src-s14\">14</a></sup> This applies where they allow waste that composts like bio-waste to be collected with it and suitable collection and treatment are available.<sup><a href=\"#src-s14\">14</a></sup>\n\nDesign-for-recycling criteria apply from 1 January 2030 and “recycled at scale” from 1 January 2035, both at the earliest.<sup><a href=\"#src-s14\">14</a></sup> From 1 January 2038, packaging must reach at least grade B.<sup><a href=\"#src-s13\">13</a></sup>\n\n<figure>\n<div data-figure=\"capsules-and-the-environment-rules-timeline\"></div>\n<figcaption>Dates of the EU packaging and green-claims rules for coffee capsules and pads, with the Swiss packaging ordinance for comparison, as of October 2026.<sup><a href=\"#src-s13\">13</a>,<a href=\"#src-s14\">14</a>,<a href=\"#src-s15\">15</a>,<a href=\"#src-s16\">16</a>,<a href=\"#src-s18\">18</a>,<a href=\"#src-s19\">19</a>,<a href=\"#src-s20\">20</a></sup> “Earliest” marks dates that move later if the implementing or delegated acts come late.</figcaption>\n</figure>\n\nSwitzerland has its own rules. A new ordinance for all packaging, adopted on 24 June 2026, applies from the start of 2027.<sup><a href=\"#src-s18\">18</a></sup> The Federal Council’s announcement does not mention coffee capsules.<sup><a href=\"#src-s18\">18</a></sup>\n\n## Claims on capsules\n\nWords such as “recyclable” or “compostable” on a capsule pack are environmental claims. EU rules applying through national law from 27 September 2026 ban generic claims such as “eco-friendly”.<sup><a href=\"#src-s19\">19</a>,<a href=\"#src-s20\">20</a></sup> The exception is recognised excellent environmental performance relevant to the claim.<sup><a href=\"#src-s19\">19</a></sup> In the United States, a federal guide calls it deceptive to misrepresent a product or package as compostable.<sup><a href=\"#src-s21\">21</a></sup> The sustainability claims entry covers these rules in detail.\n\n<!-- deep-dive -->\n\n## The studies compared\n\nThe table gives each study’s functional unit, boundary, setting and backers as far as the text consulted states them.

By way of derogation from Article 6(1), by 12 February 2028, where packaging referred to in Article 3, point (1) (f), and sticky labels affixed to fruit and vegetables are placed on the market, that packaging and sticky labels shall be compatible with the standard for composting in industrially controlled conditions in bio-waste treatment facilities and shall be compatible, where required by the Member States, with the home-composting standards referred to in paragraph 6 of this Article.”\n\nArticle 3(1), point (1)(f) covers “a permeable tea, coffee or other beverage bag, or soft after-use system single-serve unit” that contains the beverage and is “intended to be used and disposed of together with the product”.<sup><a href=\"#src-s14\">14</a></sup> Point (1)(g) covers “a non-permeable tea, coffee or other beverage system single-serve unit” “intended for use in a machine”.<sup><a href=\"#src-s14\">14</a></sup> Article 9(1) therefore applies to pads and soft units, not to capsules.<sup><a href=\"#src-s14\">14</a>,<a href=\"#src-s15\">15</a></sup>\n\nArticle 9(2) is the capsule provision. By derogation from Article 6(1), Member States that allow waste with properties similar to bio-waste in its collection, where “appropriate waste collection schemes and waste treatment infrastructure are available”, “may require that the following packaging shall be made available on their territory for the first time only if the packaging is compostable”.<sup><a href=\"#src-s14\">14</a></sup> Point (a) names packaging under point (1)(g) “composed of material other than metal”.<sup><a href=\"#src-s14\">14</a></sup> Recital 54 refers to the same units.<sup><a href=\"#src-s13\">13</a>,<a href=\"#src-s14\">14</a></sup>\n\n**Standards.** The Commission states that the existing standard EN 13432 on industrial composting “can be used as guidance until the new standard is adopted”.<sup><a href=\"#src-s14\">14</a></sup> The guidance states that the Commission would ask the European standardisation bodies for a new EU-wide standard on home compostability by 12 February 2026.<sup><a href=\"#src-s14\">14</a></sup> According to the Commission, home composting “should only be considered in the context of specific local conditions” and under the supervision of the authorities.<sup><a href=\"#src-s14\">14</a></sup> The criteria of EN 13432 themselves were not consulted for this entry, so none are given.\n\n## Compostable capsules in practice\n\nA 2020 Dutch trial placed used compostable capsules (polylactic acid, PLA, with biodegradable polyesters) and used pads (paper and PLA fibres) in mesh bags in a full-scale composting plant.<sup><a href=\"#src-s11\">11</a></sup> Each cycle ran for 11 days with aeration and moisture.<sup><a href=\"#src-s11\">11</a></sup> After two cycles, 91% of the capsule mass was recovered from one bag and 59% from the other; for pads, 58% and 86%.<sup><a href=\"#src-s11\">11</a></sup> The authors call these percentages indicative, because samples were not fully cleaned and some bags were damaged.<sup><a href=\"#src-s11\">11</a></sup>\n\nThe authors expect more fragmentation in processes that apply shear.<sup><a href=\"#src-s11\">11</a></sup> They did not expect pre-treatment such as sieving to put more capsules into the plant’s residual streams.<sup><a href=\"#src-s11\">11</a></sup> They note that even tiny capsule fragments remain conspicuous in the dark brown compost.<sup><a href=\"#src-s11\">11</a></sup> The trial covers one plant and one capsule product.<sup><a href=\"#src-s11\">11</a></sup>\n\nA 2020 US study compared PLA-based compostable pods with PP pods, counting packaging only.<sup><a href=\"#src-s10\">10</a></sup> Composting the compostable pods gave the lowest impacts in 7 of 10 categories, but their embodied energy was 6.1% higher than that of the PP pods, even in the best case.<sup><a href=\"#src-s10\">10</a></sup> The work was funded in part by the US Department of Energy.<sup><a href=\"#src-s10\">10</a></sup> According to Wageningen University & Research, its 2023 report ranked compostable capsules first and aluminium second, the latter only with separate collection.<sup><a href=\"#src-s12\">12</a></sup> The project was co-funded by makers of compostable materials.<sup><a href=\"#src-s12\">12</a></sup>\n\n## Reference values\n\n| Parameter | Value | Functional unit and boundary | Source |\n|---|---|---|---|\n| Packaging share of coffee footprints | Median 9–18% (higher for pods and capsules) | Across 34 LCAs | Chéron-Bessou et al.<sup><a href=\"#src-s1\">1</a></sup> |\n| Coffee per cup, as assumed | 6.5 g capsule;

assumptions on dilution and wasted coffee differ between studies, and a 2024 review recommends standardising the functional unit.<sup><a href=\"#src-s1\">1</a></sup>\n- How much coffee households brew and pour away is the deciding assumption in capsule–filter comparisons; the studies consulted assume it rather than measure it.<sup><a href=\"#src-s3\">3</a>,<a href=\"#src-s5\">5</a></sup>\n- No official or peer-reviewed collection or recycling rate for coffee capsules was found for this entry.<sup><a href=\"#src-s17\">17</a></sup>\n- A harmonised EU standard for compostable packaging, including home composting, had not yet been adopted as of the Commission’s 2026 guidance.<sup><a href=\"#src-s14\">14</a></sup>\n- Whether compostable capsules disintegrate fully in plants with short cycles has been tested in few full-scale trials;
