ECO-SOLIDS INTERNATIONAL LIMITED was formed by Managing Director, Clive Rigden, in the spring of 2003 to further develop the technologies originated and put into commercial operation by Samuel Shepherd in Texas, and to market these world-wide.

The company, based on the South Coast of Great Britain and with offices near Houston, Texas, has embarked on a programme of education, demonstration and marketing to government agencies, municipalities and wastewater treatment companies world-wide.

Works using the ECO-SOLIDS PROCESS are established in the USA and have been operating with commercial success for some considerable time - and the world's first CELLRUPTOR® unit has been installed at a Yorkshire Water STW in Great Britain.

ECO-SOLIDS INTERNATIONAL LIMITED would be delighted to arrange for parties considering the implementation of the ECO-SOLIDS® PROCESS to visit operational works and see for themselves the technological, commercial and environmental benefits the process creates for operators, customers and communities as a whole. Similarly, visits to the CELLRUPTOR® commercial trial site may also be arranged, strictly by prior appointment with ECO-SOLIDS INTERNATIONAL LIMITED.


Eco-Solids International is committed to the development and commercialization of environmental technologies for the processing of organic residues.  Our aims are to reduce processing costs, and maximize the benefits of these processes through excellence in science and engineering application, and to convert today’s low grade wastes into tomorrow’s renewable energy and recyclable carbon and nutrients.

We will grow in international markets with carefully selected partners, and technologies appropriate to the needs and economics of each given region.
