Cercetătorii de la Universitatea din Florida, SUA au experimentat un procedeu de procesare a unor deşeuri de alimente şi hârtie de ziar, în urma căruia au obţinut etanol. Caracteristica acestei metode este publicată în revista ştiinţifică Jurnal Oficial Plant Biotehnology citată de presa internaţională (Europa Press).
Potrivit profesorului Henry Daniell, şeful grupului de cercetare ‘'metoda este ecologică şi mult mai ieftină decât cele disponibile pentru procesarea combustibilului actual, iar reziduurile alimentare, deşeurile de hârtie sau anumite resturi materiale sunt inepuizabile''.
