Abstract

The large-scale exploitation of Hyblaean asphalt rock began in the last decades of the nineteenth century. After World War I, the production of combustibles and refined lubricating oils using asphalt rock waste material joined the production of bitumen, briquettes, asphalt mastic, and so on, produced mainly for export. The slump after World War II caused the disappearance or the incorporation of marginal firms. Finally, when control of the sector was handed over to ENI (in 1968), the production of polyethylene and cement was encouraged to the detriment of more established products. The take-off of the large scale exploitation of Hyblaean asphalt rock occurred starting from 1858. The proliferation of factories based on the digging out and processing of the raw rock for the production of bitumen, asphalt mastic and briquettes, etc., caused relevant increases in the output. After the 1st World War new facilities were aimed to the production of refined and ho-mogeneous combustibles and lubricating oils and, at the same time, allowed the resolution of the problem of the missed exploitation of most asphalt rock wastes. The recession after the 2nd World War caused the disappearance or the incorporation of the marginal firms. In the seven-ties, with the ENI model, the production of polyethylene and cement encouraged, leaving the other traditional productions.

Lo sfruttamento su vasta scala dei giacimenti di roccia asfaltica iblea ebbe avvio a partire dagli ultimi decenni dell’Ottocento. Dopo la I guerra mondiale, alla produzione di bitume, mattonelle di compresso, mastice d’asfalto, etc., principalmente destinati all’esportazione, si affiancò l’utilizzazione del materiale di scarto per la produzione di combustibili ed oli lubrificanti purissimi. Nel secondo dopoguerra, la reces-sione portò alla scomparsa o all’assorbimento delle imprese marginali. Infine, con il passaggio del con-trollo del settore all’ENI (nel 1968), fu promossa la produzione di polietilene e cemento, a discapito delle produzioni di più antica tradizione.
