This final process might have saved the company. Successful trials with existing modified plant showed that large scale reclamation of useful products from used tyres was possible. However it came too late to prevent financial collapse. This was attributed by the company to the delayed response of the regulating authorities in granting licenses for the sale of the tyre oil as fuel.

Famous quotes containing the words processes and/or products:

    “All the followers of science are fully persuaded that the processes of investigation, if only pushed far enough, will give one certain solution to each question to which they can be applied.... This great law is embodied in the conception of truth and reality. The opinion which is fated to be ultimately agreed to by all who investigate is what we mean by the truth, and the object represented in this opinion is the real.”
    —Charles Sanders Peirce (1839–1914)

    “The reality is that zero defects in products plus zero pollution plus zero risk on the job is equivalent to maximum growth of government plus zero economic growth plus runaway inflation.”
    —Dixie Lee Ray (b. 1924)
