Description
One objective of the project is to conduct a research about the most effective methods in the reduction of sulphates which would reach 1 g/l in the environment an process the remaining waste which contains sulphates. Another objective is to implement new technologies in manufacturing of glass fibre and textile production and introduce a new “green” line of products. The new technology will consist of two pieces of equipment: (1) Retardation facility for the recovery of sulphuric acid from wastewater with efficiency of 60-80% that will be reused in production. (2) Neutralization plant with Nano filtration and sludge press, that would provide amount of sulphates and other hazardous substances going into environment (as waste water) decrease from 9g/l to 1g/l. The new technologies will also provide decrease of carbon dioxide by 620 tons/year. As a result the new product will promote as environmentally friendly.
Summary of project results
Valmiera Glass Group, with headquarters in Valmiera, Latvia, is one of the leading European manufacturers of glass fibre-based products. The Group companies are located on two continents in three countries: in Latvia, the United Kingdom and the United States. In 2016, in Latvia, the Company completed Norway grant project that implemented technology that has never been used by the Company and it is unic . Before the project implementation the Company dealt with high levels of sulphur acid emissions into water, high consumption of raw materials without a possibility of reuse, high consumption of resources without any possibility of re-use of resources. The new technology significantly increases the quality of waste water, reduces the pollution in production process by reducing CO2 emissions by 620 tons/year and sulfate emissions by 60%, technology gives opportunity to reuse sulfur acid resources.
