The coal industry had been decimated and virtually closed down , and the steel industry had suffered huge job losses , as had the petrochemical industries and heavy engineering

Yr oedd y diwydiant glo wedi'i ddistrywio a'i gau bron , a chollwyd nifer enfawr o swyddi yn y diwydiant dur , ac mewn diwydiannau petrocemegol a pheirianneg drwm yn yr un modd

An unconventional source of capital eventually solved his problem -- Shell Ventures , a branch of the petrochemical company devoted to backing ` blue-skies ' hi-tech ideas

Yn y diwedd , daeth yr ateb i'w broblem o ffynhonnell anghonfensiynol -- Shell Ventures , cangen o'r cwmni petrogemegol sydd wedi ymroi i gefnogi'r syniadau technolegol ` delfrydol ' diweddaraf

Andrew Davies and I have had meetings with major investors and have visited the area to discuss what can happen in the petrochemicals sector as regards the liquefied natural gas facilities that are proposed by Esso and Petroplus , and , of course , the Bluestone project , which is subject to planning permission

Today his work is vital in a range of subjects from petrochemicals to medicine

Heddiw mae ei waith yn hollbwysig mewn ystod o bynciau o betro-gemegion i feddyginiaeth
