Teesside industry is dominated by the commodity and integrated chemical producers in the
North East of England Process Industry Cluster (NEPIC). These companies are based on three large chemical sites at
Wilton,
Billingham and
Seal Sands. These companies make products such as
petrochemicals,
commodity chemicals,
fertilizers and
polymers.
Salt Salt extraction for human consumption and had taken place at
Seal Sands since Roman times through the use of panning. This continued throughout the 20th century and left caverns which are now used as liquid/gas storage facilities for the process industry. In 1859,
rock salt deposits were discovered in Middlesbrough by
Henry Bolckow and
Vaughan while boring for water. This led to heavy chemical industry moving to the area. Salt works were established at Haverton Hill in 1882 by the Bell Brothers. It was the first firm to begin large scale salt production in the area, this required some workers in from Cheshire. Salt-making interests of the Bell Brothers were bought by
Brunner Mond & Co of Cheshire in 1890. Brunner Mond became a giant of the area's chemical-making in the late 19th and early 20th centuries. During the 20th century, salt extraction on the Tees's north bank (by aqueous hydraulic means) resulted in a number of underground salt cavities that are impervious to gas and liquids. Consequently, these cavities are now used to store both industrial gases and liquids by companies which are members of the
Northeast of England Process Industry Cluster (NEPIC). Today Venator Materials is based close to Greatham, operating one of the world's largest
chemical plants for
titanium dioxide manufacturing. It is a brilliant white
pigment used in paints, Polo mints, cosmetics, UV sunscreens, plastics, golf balls, the white part of a traffic cone and sports field line markings.
Alkali In 1860 William James established an alkali company at Cargo Fleet and in 1869
Samuel Sadler also set up a factory nearby. Sadler's works produced synthetic aniline and alzarin dyestuffs and distilled tar. The introduction of the
Solvay Process to make alkali in 1872 made nearby Tyneside alkali industry uneconomical but helped Teesside industry which was invigorated by the discovery of further salt deposits at Port Clarence near Seal Sands by Bell Brothers in 1874. The 700 acre Grange Farm at Billingham was chosen for the site. However, by the time the plant opened the war was over and its manufacturing techniques outdated. It was taken over by Brunner Mond in 1920 and manufactured synthetic ammonia and fertilisers. Brunner Mond merged with other large scale chemical manufacturers in 1926 to form
Imperial Chemical Industries (ICI).
Sulphuric acid and fertilisers Teesside's first chemical works was when Robert Wilson produced sulfuric acid and fertilisers at Urlay Nook near Egglescliffe in 1833. In 1928, anhydrite was mined from below Billingham for making
sulfuric acid, a component for
detergent and
fertilizer manufacturing. This was one of the earliest sites in the world where large-scale manufacture of these materials took place. Another
chemical plant was established the following year to make oil and petrol from
creosote and coal by a process called
hydrogenation. In 1946 another large chemical works opened on Teesside at
Wilton, on the south side of the
River Tees. Further lands were purchased by ICI in 1962 at Seal Sands, where land had been reclaimed from the sea, becoming the third large-scale chemical manufacturing site on Teesside. Today, ConocoPhillips operate oil refinery sites while Ensus Energy and Harvest Energy have biorefineries, the latter two produce
biodiesel and
bioethanol as transport fuels.
SABIC operate the ethylene cracker at Wilton. ==Metal works==
