Our Proprietary Technology.
Syntech International Srl is a technology provider in reprocessing and recycling industrial acidic wastes, especially Sulfuric and Nitric acids, as well as their mixtures. Our mission is the study of chemical processes and the development of our Clients’ industrial applications, in view of a modern approach to green and sustainable process chemistry. This design philosophy is carried out by means of more environmental-friendly practices and solutions, such as Zero-Liquid-Discharge (ZLD) approach.
Through a strategic plan of licence acquisitions supported by a continuous development by our internal process team, we are proud to announce that we are a Technology Provider of both Process Units and Plants belonging to the categories reported here below.
