Abstract. The Wastewater Treatment Plant (WWTP) 'Swarzewo' plays a special role in the protection of coastal waters of the Baltic Sea area and the management of solid wastes in the region. This paper discusses several options implemented in the WWTP area in order to achieve sustainability. The first one was the inclusion of WWTP into municipal waste management plan to increase the biogas production and to reduce volume of organic waste in the region. Nowadays, daily production of about 2000 m 3 of biogas is gained. The energy balance shows a considerable benefit from the co-fermentation of sludge with municipal organic wastes. The next goal was to obtain a favorable economical balance of energy and high level of pollution reduction. The last one was the involvement of local communities in a conscious segregation of waste 'at source'. For the purpose of this paper bio-energy production, nutrient elimination, composting, and research, have been selected as indicators of sustainable development. Furthermore, in this study the methods of nutrient recovery from wastewater were explored. Struvite precipitation and compost production were presented as an example of nutrient elimination with 'end of waste' production. Depending on the struvite precipitation conditions, recovery of 4 Mg of phosphorous and 1,8 Mg of nitrogen is possible to obtain annually.

“…As a result, the cogeneration plants work in the condensing regime as power plants. Currently there are no plans for bio-waste treatment facilities to be installed in Latvia, except for equipment for mechanical pre-treatment of waste [10]. Thus, it can be projected that a rapid decrease in landfill gas emissions cannot be expected in the near future.…”

A mathematical model was developed and applied to estimate an optimal installed capacity of a power plant that uses landfill gas as a fuel. Economic, technological and climate parameters are considered in the model. For benchmarking purposes the feed-in tariffs of power production from renewable energy sources, as well as price of CO 2 emission allowances are used. A landfill in Latvia is taken as a case for modelling. The results show that it is possible to find the optimal capacity for various grades of landfill gas quality.

Eco-innovation will play a major role in contributing to a sustainable future. Understanding the diffusion is critical, since the diffusion rate is slow and the path unclear. We present the conceptual methodology for eco-innovation diffusion. This methodology combines mixed and combined research methodology to improve the validity and reliability of results. A survey is used as a quantitative method; artificial neural networks and system dynamic are applied as qualitative methods. With this article we aim to contribute to the applications of combined and mixed methods research in the field of eco-innovation diffusion. The application of the presented methodology can be extended for other problems.
