This wont answer your question, but will attempt to show, why the question is based on wrong assumptions.
That headline you're concerned about is missing a "yet". True, currently recycling possibilities are few and have low capacity, but research is conducted and start-ups are being founded. I think those blades wont be lingering forever in landfills.
The Bundesverband WindEnergie (German Wind Energy Association) is an association of companies which produce, erect and operate wind turbines. It released a paper on recycling options for wind turbines (the paper is in German, sorry). Points 3.9.1 and 3.9.2 deal with your question/assumption.
Older rotor blades (those reinforced with fibre-glass) are shredded and for example used during concrete production. Thus 1,000 tons of shredded rotor blades substitute 450 tons coal, 200 tons chalk and 200 tons sand in a mixture of replacement fuel and silicate substitute (pp. 8-9).
Newer blades (those with carbon fibres) are more problematic to use for "thermic recycling" due to the electric properties of said fibres. They need to be shredded and then heated under exclusion of oxygen but after separation can be used for car parts or in engineering, even for 3D-printing (p. 10).
Companies are aware of the recycling issue and are working on it - so, while currently there are some issues to tackle, they are managable. Also, please remember that the waste produced by wind turbines is several magnitudes smaller than our everyday waste.
