Six of our studies on appliance lifespan: what Czech consumers expect, how washing machine lifespans have evolved, why planned-obsolescence beliefs don't change purchase behaviour — and how many end-of-life appliances escape official statistics. With links to the full texts.
Why we study lifespan
Almost all the lifespan evidence underpinning European repairability and Ecodesign policy comes from Western and Northern Europe. Central and Eastern Europe is nearly invisible in the literature — yet the rules calibrated on that evidence apply here too. Our research series aims to close that gap systematically. Below is a digest of the six studies our methodology builds on, including the main quantitative results and links to the full manuscripts.
1. Lifespan of major household appliances in Czech households
This study combines a review of the international lifespan literature with our own survey of Czech households across four categories: washing machines, refrigerators, dishwashers, and tumble dryers. It is the first multi-appliance comparison from the Czech Republic — until now, Czech data was essentially absent from European durability debates. The study shows for which categories Czech experience matches the reference lifetimes used in EU policy and where it diverges, creating a comparative baseline for the regional durability and repairability debate.
Why it matters: the reference lifespans the EU builds policy on (e.g. in Ecodesign) cannot simply be transplanted to the Czech market — regional transferability is an empirical question, not an assumption.

2. Washing machine lifespan: the first estimate from Central and Eastern Europe
The washing machine is the most studied appliance in European durability research — yet no published estimate had ever come from Central and Eastern Europe. This study provides the first Czech estimate of washing machine lifespan, based on a household survey and Weibull lifespan modelling, benchmarked against the Western European evidence base. It also clarifies how survey-based lifespan estimates should be interpreted for circular-economy and WEEE analysis.
Why it matters: waste and repair policy for large appliances rests on data whose regional transferability nobody had tested. Now somebody has.

3. What Czech consumers expect — versus EU Ecodesign references
A cross-sectional online survey (December 2025) of 408 Czech adults aged 30+ who are involved in appliance purchasing decisions, analysed with interval-censored Weibull models and ordered logistic regression, with Benjamini–Hochberg correction for multiple comparisons. Mean expected lifespans: 11.5 years for washing machines, 12.6 for refrigerators, 11.7 for dishwashers, and 12.0 for tumble dryers. Refrigerator expectations align closely with the EU reference; washing machines and dishwashers fall roughly one year below the 12.5-year Ecodesign reference, while dryer expectations (12.0 years) already match the revised reference planned for 2027. The strongest predictor of higher expectations is the age of the appliance the household currently uses. Two-thirds of respondents endorse the view that manufacturers deliberately shorten lifespans — yet their quantitative estimates remain broadly consistent with EU benchmarks.
Why it matters: consumer expectations shape replacement timing and willingness to pay for durability. Regional differences mean a one-size-fits-all EU policy may not work equally everywhere — and our data shows precisely where Czech expectations already support the EU references and where they may constrain them.

4. Planned obsolescence beliefs and the Durability Expectations Gap
The same sample of 408 consumers also rated 15 appliance brands across six quality and durability dimensions. Three principal findings. First, planned-obsolescence beliefs are pervasive and internally consistent (mean 5.24 on a 7-point scale, Cronbach's α = 0.896). Second, there is a significant Durability Expectations Gap: consumers expect new appliances to last substantially longer than the current age of their existing ones (gap ≈ 1.7 category intervals, p < 0.001, Cohen's d = 0.94–1.50). Third — and most critically — planned-obsolescence beliefs predict the gap (β = 0.128, p = 0.012) and reduce confidence in lifespan estimation (β = −0.157, p = 0.002), yet they do not influence purchase preferences. The dominant predictor of purchase decisions is perceived brand quality (β = 0.320, p < 0.001).
Why it matters: the results point to a paradox of "resigned consumer rationality" — consumers suspect deliberate quality degradation but, lacking credible durability information, default to brand heuristics. The policy implication is that awareness campaigns alone are insufficient; what is needed is mandatory, credible durability labelling. That information gap is exactly what our score aims to fill.

5. Where end-of-life washing machines disappear: missing WEEE in the EU-27
A stock-driven dynamic material flow analysis (MFA, 1993–2023) for washing machines across the EU-27, calibrated with a synthesis of six independent lifespan anchors (1960–2023) into cohort-specific Weibull survival functions. For 2023: modelled disposals of 14.4 million units against official collections of 8.5 million — a collection gap of 5.9 million units, about 41% of disposals (Monte Carlo 5th–95th percentile: 4.5–7.2 million). Across 2011–2023 the gap persists at 36–56% of annual disposals. Complementary interviews with repair technicians (n = 8, Czech Republic) indicate that spare-parts availability and repair-cost thresholds materially limit repair.
Why it matters: the official WEEE statistics used to measure circular-economy performance systematically understate reality. The findings are directly relevant to WEEE enforcement, extended producer responsibility (EPR) design, and digital product passport implementation under Regulation (EU) 2024/1781.

6. Declining washing machine lifespans and repair barriers (1960–2023)
This study integrates three methods: anchor-constrained Weibull survival analysis, a stock-driven EU-27 MFA, and semi-structured interviews with repair technicians (n = 8, Czech Republic). Headline results: average washing machine lifespans declined by 44.8% — from 19.2 years (1960) to 10.6 years (2023) — with the analysis attributing the decline primarily to usage intensification rather than planned obsolescence. Approximately 9.7 million units per year (~52%) evade official WEEE collection (the estimate differs modestly from study 5 due to different lifespan calibration and mass-to-unit conversion; the two uncertainty ranges overlap). And although 69% of disposals stem from technical faults, only 22% are repaired — spare-parts costs have inflated at 3–4× the consumer price index, and diagnostics are increasingly difficult for independent repairers.
Why it matters: the planned-obsolescence debate often conflates shorter lifespans with manufacturer intent. Our data paints a more sober but politically weightier picture: lifespans genuinely are declining, and repair is blocked by economic barriers — which is where regulation should aim.

The takeaway
Appliance lifespan is not just an engineering number — it is an input into policy, prices, and consumer decisions. Our data shows Czech reality differs from Western European assumptions enough to be worth measuring. All findings feed into our ratings database and methodology.
