Sustainability assessment methods are needed to support sustainable technology development and to evaluate the impacts of existing solutions, products and technologies. While there are aspects and indicators that are common to all process industries, sector specific tools are required to address the sector specific features in a fair and transparent way. At the moment, several tools, assessment methods and indicators exist, but they differ in their goal and scope and are intended for different kind of use within companies, by consumers or by authorities to support policy planning and evaluation. Additionally, different tools are focused for different levels of assessment: product, company, industry or society. Thus the problem is not so much the existence of proper tools but rather the lack of understanding and knowledge on how they should be applied and in which context. Furthermore, suitable tools for analysing resource and energy efficiency within the process industries and across the different sectors should be recognized. The aim of the SAMT project is to review and make recommendations about the most potential sustainability assessment methods for evaluating energy and resource efficiency in the process industry. The analysis will focus on the applicability of different methods in industrial settings, the ability of the methods to support decision-making towards sustainable solutions and the suitability of the tools for cross-sectoral analysis. SAMT will evaluate tools that cover either environmental, economic and social aspects, or a combination of these, and apply principles of life cycle thinking. The project will consider demands and make recommendations related to sectorial and cross-sectorial assessment in a wide spectrum of process industries: cement, metal, oil, water, waste and chemical industry. To maximize the impact of the project the work will be supported by active dissemination activities including an implementation strategy as an outcome.

The present invention relates to a method and equipment for recovering heat from exhaust gas removed from an industrial process, such as an electrolysis process for the production of aluminium. Heat is recovered by means of an extraction/suction system, where the exhaust gas contains dust and/or particles. The heat is recovered as the exhaust gas being brought into contact with heat-recovery elements. Flow conditions and the design of the heat recovery elements are such that the deposits of the dust and/or particles on the surfaces stated are kept at a stable, limited level. In preferred embodiments, the heat-recovery elements have a circular or an extended, elliptical cross-section and may be equipped with fins or ribs.

The invention relates to a method and a system for handling long objects, in particular packing extruded profiles. It comprises two robots with one arm each, said arm having a pair of grippers, and a control unit that coordinates and controls the movement of the robots. In the handling operation the mutual distance between the two said pair of grippers are held constant, to counteract misalignment of the object.

Hydro has entered into an agreement with Yara regarding the sale of Herøya Nett AS and the quay facility at Herøya Industrial park. The transfer, including around 30 employees, will likely occur in June 2017. The industrial site at Herøya has a long tradition and was for many years Hydro's largest production location, producing fertilizer, plastics, light metals and a number of related products. In recent years Herøya has been developed as an industrial park with a number of companies and many activities. "We are pleased to have reached an agreement with Yara regarding the acquisition of Herøya Nett and the quay facility and are confident that the operation will be continued in the best possible way," says Executive Vice President Eivind Kallevik in Norsk Hydro ASA. The transaction has limited financial effect for Hydro. Investor contact Contact Stian Hasle Cellular +47 97736022 E-mail Stian.Hasle@hydro.com
