Petroleum sludge is a complex mixture of hydrocarbons, water, metals, and suspended fine solids. The objective of this research was to develop a technique that will lead to the separation of phases ready for further reuse. A study was carried out to investigate a combination of various systems of electrokinetic cells, to which oily sludge, conditioning liquids, and different electrical potentials were applied. The developed electrokinetic phase separation is a new cost-effective technology, which in turn will permit the revitalization of petroleum sludge. This method can significantly reduce the amount of wasted sludge and can recover new fuels free of metals and water. Life cycle analysis of the recovered fuel shows that a new petroleum waste management protocol might reduce emissions of major greenhouse gases such as CO2, CH4, and N2O by 40 026 000, 1057, and 566 kg, respectively, per refinery per year.Key words: oily sludge, electrokinetics, fuel recovery, sustainable management, life cycle analysis.

The article deals with the problem facing Latvian inventors in how to develop the idea to a real product. There are often cases where innovative ideas “migrate” from original inventors to other inventors, when they turn to them to seek support for developing and supporting the idea. The main components of the guidelines are the establishment of a patent application and, in general, a description of the entire patent acquisition process and the creation of a life cycle analysis using the SimaPro software. The article is intended primarily for the development of environmentally friendly inventions, which is why the life cycle analysis is one of the main components of the article, to make it possible to conclude whether the production and use of the new product will not result in a higher “ecological footprint” than previously used technologies, paying particular attention to the inventor stage in order to accurately develop a life-cycle analysis. The article does not only explore the necessary theoretical knowledge of the realisation of the idea to the product, but also looks at the pilot case, a practical example of an innovative “dust co-firing burner” compared to the conventional natural gas burner. The life-cycle analysis compares the following steps: manufacture of plants, transportation of plants and special emphasis on the combustion phase of fuels, three scenarios are examined: a natural gas burner burning natural gas, a dust burner in which natural gas is co-incinerated and fine wood particles − dust and a dust burner burning. biomethane and wood dust. The use of such an installation would not only reduce emissions from the replacement of natural gas by wood dust, but also allow energy companies to work more effectively, as it would be possible to regulate the proportion of different fuels depending on demand, because the fuels have different heat of combustion. The article establishes a methodology to analyse the quality and implementation of inventions in response to the following key questions: − how to identify original ideas and how to protect authors from the migration of ideas; − how to collect and analyse the risks associated with migration of ideas; − how to use life cycle analysis for the assessment of the “ecological footprint” of the invention.

This paper presents the results of a study of sustainable technologies that could be used in the design of an inland leisure craft carried out with particular reference to the Norfolk and Suffolk Broads. The first phase of the study involved identifying the appropriate technologies and ranking them using stakeholder consultation and expert opinion. Subsequently life cycle analysis and life cycle costing were carried out for a hypothetical fleet of leisure craft utilizing the identified high-ranking technologies. On the basis of the outcome of the analyses, cost effective eco-friendly technologies have been identified for leisure craft design within specified scenarios.
