Waste-to-energy: 4.5% of energy

Misleading Moderate confidence Draft: right of reply pending

Parts of this claim

The claim is split into parts that are tested separately, as in the report below. Each part has its own number.

  1. CC-079A The plant will treat around 192,000 tonnes of non-recyclable waste generated locally a year (WasteServ [1])Matches the NECP design (24 t/h for 8,000 hours) and the Commission’s 190,000 t. Malta landfilled 255,000 t of municipal waste in 2024, but meeting the 2035 recycling target would leave at most 124,000 t.Consistent
  2. CC-079B It is expected to meet around 4.5% of Malta’s total energy needs (WasteServ [1, 2])126 GWh is 1.5% of final and 1.2% of primary energy consumption (2022), but 4.4–4.7% of electricity use. 3.2% of the NECP’s 2030 electricity supply.Misleading
  3. CC-079C The waste is converted into green energy (WasteServ [1, 2])Only the biodegradable fraction counts as renewable under EU law; the NECP says the plant is not expected to contribute to Malta’s renewable share.Partly
  4. CC-079D The plant will generate 126 GWh a year to the grid (WasteServ [3])Consistent with the NECP’s 14–16 MW net (112–128 GWh) and a net efficiency of 23.6%, within the 20–24% reported for plants of this size.Plausible
  5. CC-079E The plant will treat 40% of the non-recyclable waste generated in Malta (WasteServ [3])With 192,000 t this implies 480,000 t of non-recyclable waste. 192,000 t is 67–75% of the waste Malta landfills and 32% of all non-mineral waste it generates; no basis is given.Unclear basis

4.5% of Malta’s energy from burning waste?

Testing WasteServ’s figures for the Magħtab waste-to-energy plant against Eurostat and Malta’s energy plan

“This plant will be treating around 192,000 tonnes of non-recyclable waste … It is expected to meet around 4.5% of Malta’s total energy needs.”

WasteServ, ECOHIVE news, 26 June 2023.
In 2020: “adding an impressive 4.5% as green energy to Malta’s total energy demand”.

Verdict: Misleading 4.5% fits electricity; of total energy it is about 1.1–1.8%

Version 1.0 · 10 October 2026

TL;DR

In June 2023 WasteServ wrote that the waste-to-energy plant it plans at Magħtab “will be treating around 192,000 tonnes of non-recyclable waste generated locally” and “is expected to meet around 4.5% of Malta’s total energy needs”. It had used the same 4.5% in 2020, “as green energy”. We tested both figures against WasteServ’s own output figure, the plant design in Malta’s National Energy and Climate Plan (NECP) and Eurostat’s energy and waste statistics.

  1. The tonnage matches the design. 192,000 tonnes a year is two lines of 12 tonnes an hour running 8,000 hours, as in the NECP; the Commission cites 190,000 t. Malta landfilled 255,000 t of municipal waste in 2024, so there is enough residual waste today.
  2. The plant would make about 126 GWh of electricity a year. That is WasteServ’s own figure. The NECP’s 14–16 MW net and the efficiencies published for plants of this size (20–24%) agree with it.
  3. 4.5% fits electricity, not total energy. 126 GWh was 4.4–4.7% of Malta’s electricity use in 2022, but 1.5% of its final energy consumption and 1.2% of its primary energy. Electricity is only about a third of the final energy Malta uses.
  4. Only one other reading comes near 4.5%. The energy in the waste itself (about 533 GWh a year) is 5.0–5.2% of primary energy. But the plant would deliver under a quarter of it, as electricity; WasteServ names no user for the heat.
  5. “Green” needs a qualifier. EU law counts only the biodegradable part of waste as renewable, and the NECP says the plant “is not expected to contribute to Malta’s RES share”.
  6. Verdict: misleading (moderate confidence). A share of electricity is presented as a share of all energy, about three times too high. Even for electricity the share falls to 3.2% by 2030 on the NECP’s projection. WasteServ published no method.

What would move the verdict up

WasteServ’s calculation showing which energy measure and year the 4.5% uses; or design documents (the EIA, the contract) showing the plant will also supply heat, enough to bring the energy it delivers near 4.5% of Malta’s total.

What would move it down

A design or contract output well below 126 GWh a year, which would leave the 4.5% without a basis even as a share of electricity.

IN THIS REPORT

1 The claim and what we could verify

ECOHIVE is WasteServ’s project for new waste plants at the Magħtab waste complex, among them a waste-to-energy facility, a material recovery facility, an organic processing plant, a skip management facility and a thermal treatment facility for hazardous waste [3]. The news item of 26 June 2023 on WasteServ’s ECOHIVE website reported a procurement milestone for the waste-to-energy plant and ended with the two sentences quoted on the cover [1]. WasteServ’s releases of 23 October and 2 November 2020 had given the 4.5% as “green energy” added to “Malta’s total energy demand” [2]. The undated project page gives the plant’s output, 126 GWh a year, and says it will treat 40% of Malta’s non-recyclable waste [3]. We read all of them in full on 10 October 2026.

The figures reached us through Amphora Media (June 2025), which reported in its own words that in a January 2025 parliamentary answer the Environment Minister said the plant would process 40% of non-recyclable waste and provide 4.5% of the country’s energy needs [4]. We could not read that answer (the parliament’s websites refuse automated access), so we rate WasteServ’s published wording only.

FAIRNESS NOTE

WasteServ’s statements describe a plant that has not been built. In March 2026 The Shift News reported, from a parliamentary answer, that the latest procurement had been abandoned and no funds set aside for 2026 [13]. We test the figures as stated, not the project, its procurement or its environmental effects, and nothing here concerns anyone’s motives.

2 Method

Question. What could “4.5% of Malta’s total energy needs” mean, and do the plant’s expected output and Malta’s energy statistics support it on that reading? Are the tonnage and the other figures WasteServ gives for the plant consistent?

Readings. WasteServ gives no method, so we tested each plausible one. The numerator is the energy the plant delivers (126 GWh of electricity a year, WasteServ’s figure) or, as an upper bound that is not delivered, the energy content of the waste burnt. The denominator is Malta’s electricity (final consumption; inland demand) or its total energy: final energy consumption as reported for the Energy Efficiency Directive (which includes international aviation), final energy use without it, primary energy consumption, gross inland consumption and gross available energy (which also counts fuel sold to ships). Years: 2019 and 2022, the last years before the 2020 and 2023 statements, 2024 (latest) and the NECP’s 2030 projection.

Evidence. Eurostat datasets nrg_bal_c, nrg_cb_e, env_wasmun, env_wastrt and env_wasgen, downloaded with a script on 10 October 2026 (tools/cc-079-report/fetch.py); the NECP’s design figures and projections; peer-reviewed studies of electrical efficiency and of the biogenic share of burnt waste (abstracts only); EU law. Every figure is recomputed in calc.py (outputs in data/cc-079/checks.csv). Grades and the verdict scale are in Appendix A.

3 How the plant would make energy

In a moving-grate plant, mixed waste burns on a sloping grate; the hot gases raise steam in a boiler and the steam drives a turbine. Only part of the waste’s energy becomes electricity. A review of thermal treatment puts the net electric efficiency of small and medium plants that make only electricity at around 20–24%, and up to 30–31% for the largest [9]; the rest leaves as heat. Selling heat as well (co-generation) is the main way to recover more [9], and differences between European plants relate mainly to their size and to whether a heat market exists [10].

The NECP describes the Magħtab design: two moving-grate lines on one turbine, each taking 12 tonnes an hour, with a net electricity generation of 14–16 MW and a heat input to the boiler “between 20MWth and 33.33MWth” [5, p. 132]. 192,000 tonnes a year at 24 tonnes an hour is 8,000 full-load hours, 91% of the year. Reading 33.33 MWth as the heat input of each line, the design calorific value is 10.0 GJ a tonne and the waste’s energy content 533 GWh a year; 126 GWh is then a net efficiency of 23.6%, inside the range for plants of this size. Read as the total for both lines, 33.33 MWth would imply 42–48%, well above the 30–31% the review gives for the largest plants [9], so we reject that reading.

4 What the studies and data show

Against Malta’s electricity, 126 GWh a year is close to WasteServ’s 4.5%: 4.4–4.7% in 2022, the year before the June 2023 statement. Against Malta’s total energy it is 1.1–1.8% (Figure 2, Table 1), and less if fuel sold to ships is counted. Total energy also covers transport fuels, among them aviation fuel [6], and electricity is about a third of the final energy Malta uses (33% in 2022 and 2024). 126 GWh would be exactly 4.5% of 2,800 GWh (241 ktoe); Malta’s gross inland consumption in 2024 was 964 ktoe.

5 Where the evidence points different ways

What is the 4.5% a share of?

ELECTRICITY, NOT ALL ENERGY

EVIDENCE FOR A 4.5% FIGURE

126 GWh is 4.4–4.7% of Malta’s electricity use in 2022 and 4.8–5.1% in 2019, so 4.5% is a fair figure for electricity at the time of both statements. Counting all the energy in the waste (533 GWh), the share of primary energy consumption is 5.0–5.2% (2022–2024).

EVIDENCE AGAINST “TOTAL ENERGY”

WasteServ wrote “total energy needs” and “total energy demand”. Against Malta’s total energy, 126 GWh is 1.1–1.8% (2022–2024), and less if fuel sold to ships is counted. The energy-content reading counts the three-quarters of the waste’s energy that the plant would not deliver; WasteServ names no user for its heat.

WHY THEY DIFFER, AND WHAT IT MEANS HERE

The 4.5% most likely is a share of electricity described as a share of all energy; WasteServ has not published its method. Read as worded, the statement overstates the plant’s contribution about threefold (4.5% against 1.5% of final energy consumption in 2022). Even for electricity the share shrinks as demand grows: 3.2% of the NECP’s 2030 supply.

Is it “green energy”?

PARTLY

FOR

EU law counts the biodegradable fraction of municipal waste as biomass, a renewable source [14]. Radiocarbon measurements at Swiss plants found about half the carbon in burnt mixed waste to be biogenic [11, 12]. The NECP expects the waste sector to lead future cuts in Malta’s methane emissions, mainly because waste would go to the plant instead of landfill [5, p. 60].

AGAINST

Only the biodegradable part counts; the rest, mainly plastics, is fossil. Malta’s own plan shows only solar PV and biogas in its renewable-electricity trajectory and says the new thermal treatment plant “is not expected to contribute to Malta’s RES share” [5, pp. 84, 144].

WHY THEY DIFFER, AND WHAT IT MEANS HERE

“Green energy” is true at most for part of the output, and the Government’s own plan does not count the plant towards Malta’s renewable share. The Swiss carbon shares are context, not a measurement of Malta’s waste.

Will there be 192,000 tonnes of non-recyclable waste to burn?

TODAY YES; AT 2035 TARGETS, NO

ENOUGH WASTE NOW

Malta landfilled 255,000 t of municipal waste in 2024 and 286,500 t of non-mineral waste of all kinds in 2022 [7]; 192,000 t is 75% and 67% of these. Only 1.3% of municipal waste was incinerated in 2022 [8].

IF RECYCLING TARGETS ARE MET

Malta has kept the EU target of recycling 65% of municipal waste by 2035, renouncing a postponement in November 2024 [8, 15]. At the 2024 level of waste, meeting it would leave at most 124,000 t for burning or landfill, 68,000 t less than the plant’s capacity; waste would have to grow by 55% for 35% of it to fill the plant. The NECP plans to pre-sort mixed waste to take out recyclables before it reaches the plant [5, p. 132].

WHY THEY DIFFER, AND WHAT IT MEANS HERE

The tonnage is consistent with today’s landfilling, which is far from EU targets (16.7% recycled in 2024; see CC-004). Whether the plant could run full once recycling rises depends on waste growth or on other waste streams; the sources we read do not list the plant’s feedstock. ◆ MaltaToday reported that a smaller design was dropped because recycling rates were low (not read: 403).

Figure 3. Malta’s municipal waste generated and landfilled, 2010–2024, against the plant’s capacity and the most that would be left for burning or landfill in 2035 if the recycling target were met at the 2024 level of waste.

6 Testing the claim

WasteServ’s two sentences of 26 June 2023 are sub-claims A and B; its 2020 wording adds C; the project page supplies D, the output on which every reading of the 4.5% depends, and E. WasteServ gave no reasoning for the 4.5% that we could check.

7 Verdict and requests for evidence

VerdictMisleading

The 4.5% fits the plant’s expected electricity as a share of Malta’s electricity, not of its total energy needs, where it is about 1.1–1.8%. Confidence: moderate.

Why. The tonnage and the output WasteServ gives are consistent with the plant design in the Government’s own energy plan. The share is not: “total energy needs” and “total energy demand” name all of Malta’s energy, of which the plant’s 126 GWh would be about 1.1% (gross inland consumption, 2024) to 1.8% (final energy use without aviation). The figure of 4.5% matches the plant’s output as a share of Malta’s electricity in the years before the statements, or the whole energy content of the waste, most of which the plant would not deliver. Either way the overall impression, that burning Malta’s residual waste would meet 4.5% of all the country’s energy needs, is inaccurate. The “green energy” label adds to it: the NECP does not count the plant towards Malta’s renewable share.

Why moderate confidence. WasteServ published no method, the plant’s final design is not settled, and we could not read its EIA. A plant that also delivered most of its heat would supply more energy than the electricity alone; no heat user is described in any source we read.

What this verdict does not say. It does not judge whether Malta should build a waste-to-energy plant, the procurement or the plant’s emissions. The tonnage and the electricity output are consistent with the design.

Evidence we are asking for

  • From WasteServ: the calculation behind the 4.5%: which energy measure, which year and which output figure.
  • From WasteServ: whether the plant will supply heat, to whom and how much, and its expected net electricity in the current design.
  • From WasteServ or ERA: the Environmental Impact Assessment’s design calorific value, feedstock list and energy balance (we found no readable copy).
  • From the Ministry for the Environment, Energy and Public Cleanliness: the text of the January 2025 parliamentary answer reported by Amphora Media.
  • From the Energy and Water Agency: whether any of the plant’s output will count towards Malta’s renewable share, given the NECP’s statement that it is not expected to.

RIGHT OF REPLY

Before wider circulation this draft should be sent to WasteServ, with a fixed deadline. Responses will be appended and the verdict revisited. Under the project’s rules a Misleading verdict is not circulated beyond this site before the reply deadline has passed.

8 Limitations

  • WasteServ published no method for the 4.5%. We tested every reading we could think of; there may be another.
  • The design may change. The figures are from the NECP (December 2024) and WasteServ’s pages; the latest procurement was abandoned, as The Shift News reported [13] from a parliamentary answer we did not read.
  • We could not read the plant’s EIA; its calorific value, heat use and net output are taken from the NECP. The heat-input figure does not say whether it is per line; we tested both readings.
  • The NECP’s Figure 120 (2030 electricity by source) has a legend whose colours do not clearly match its slices; we used only the total of the slices as a denominator.
  • The journal studies were read as abstracts. The Swiss biogenic shares are context, not measurements of Malta’s waste. No peer-reviewed study of this plant was found in Crossref; an OpenAlex search was refused (rate limit).
  • Eurostat revises energy balances; the 2024 values are the latest published on 10 October 2026.
  • Amphora’s account of the Minister’s parliamentary answer is the outlet’s paraphrase and is not rated.

Appendix A: series standards and verdict scale

Every investigation in this series follows the same rules so that verdicts are comparable and challengeable.

VerdictMeaning
SUPPORTEDEvidence consistently backs the claim as stated.
LARGELY SUPPORTEDBacked by the evidence, with minor caveats that do not change the substance.
NOT SUBSTANTIATEDStated more strongly than the evidence offered or available allows. May be true in some conditions but has not been shown.
MISLEADINGOmits material facts so that the overall impression is inaccurate, even if individual statements are defensible.
CONTRADICTEDThe available evidence points against the claim.

Confidence

High: multiple independent lines of evidence agree. Moderate: evidence is relevant but incomplete or indirect. Low: evidence is thin, second-hand or conflicting.

Evidence grades

A experiment · B observational study with a control or gradient · C review, guidance or official statistics · D assertion or anecdote. ◆ marks a source known only second-hand. A speaker’s figure given without data or method (here WasteServ’s 126 GWh and 4.5%) is graded D.

Standards

  • Quote the speaker, not the headline, with outlet and date, and link the original where possible.
  • Separate the claim from the evidence offered for it, and say who made which statement.
  • Grade the evidence and show differing views side by side where the evidence is unsettled.
  • State what we could not access or verify, and what would change the verdict either way.
  • Ask for the missing evidence in specific, answerable requests.
  • Offer a right of reply where a check finds a claim Not substantiated, Misleading or Contradicted (or a pledge Not measurable, Off track or Missed), before wider circulation, and append responses.
  • Correct errors openly with a version number and change log.
  • Whistle-blow only on evidence: a verdict of Misleading or Contradicted requires documents or data that can be shown, not inference.
  • Check every side. Government, opposition, NGOs and developers are held to the same standard.

Right of reply

The body concerned has not yet been asked to reply. Its response will be published here, beside the verdict.

How this claim relates to the others: who made it, the themes it shares with other claims, and the patterns it shows. A connection is a reason to read two checks side by side. It does not make either one right or wrong. How connections are found.

Who made it

WasteServ

Other claims by WasteServ 2

Linked directly 4

Claims that share a theme with this one. A theme is a cause, a mechanism, a target or a way of presenting figures that the editors have found in several claims; its strength says how close the link is.

Waste and construction Shared material flow · Weak (indicative)

Inert mineral waste dominates Malta's recycling statistics, which ties waste claims to development projects. ERA and NSO confirm construction waste was about 2.2 of 2.9 Mt generated in 2023; the link to specific projects is still indicative.

Selective-metric pattern Rhetorical pattern · Pattern, not causal

A favourable metric is cited while the regulator-relevant metric looks worse. Useful for tagging, not for implying a common cause.

Same pattern

Pattern tags name a recurring way a claim can mislead. They describe the statement, not the speaker.

Selective metric

A favourable metric is cited while the regulator-relevant metric looks worse.

Promise-without-baseline

A target or pledge with no stated starting point, scope or counting basis.

Two steps away 8

Not linked to this claim directly, but linked to a claim that is. These are found by following the links, not chosen by the editors, so they are looser: they show where one theme meets another.

Three steps away 29

One step further again. At this distance a connection says more about how the themes fit together than about this claim.

Similar wording

Claims whose own words overlap with this one, with the words they share. Found by comparing the wording of the claims, not their verdicts; a lead to read them together, not a finding.
