Article
Full-text available
A very small part of waste management has been carried out by incineration in Finland.About 300 kt of waste is incinerated or burned with other fuels. Waste materials have beenused in energy production mostly as co-combustion fuels at several energy production plants.The waste incineration directive of the European Union sets tight regulations for...
Article
Full-text available
This study addresses the challenges in ensuring energy efficiency and high indoor climate quality with efficient use of public money in the municipal building procurement process. Energy efficient municipal building procurement provides a significant leverage when steering the built environment towards the low-carbon economy targets of the EU. Muni...
Article
Full-text available
This paper proposes an extension for feasibility assessment of residential energy (heat and electricity) supply solutions in an operational environment undergoing major changes. In order to improve the life cycle economy of the energy supply, the design has to accommodate technological, economic, and regulatory changes in operational environment ov...
Article
Distributed energy systems (DESY) are used in many households as an alternative to conventional centralized energy production. While centralized energy production does offer certain advantages, there is growing interest in smaller distributed renewable energy production options. This study uses combines two different methodologies, namely life cycl...
Article
This article focuses on the saving potential of butanol as regards greenhouse gas (GHG) emissions. It is known that butanol can be used as a biofuel to decrease the greenhouse gas emissions from transport and that butanol may overcome blend wall limitations better than ethanol. However, the GHG emissions of butanol are not well known. The study is...
Article
Organic Rankine cycles have been identified as a suitable technological option for converting low-grade heat into electricity with relatively high efficiency, and the organic Rankine cycle technology has been successfully implemented in different power production systems and in recovering heat in industrial processes. This paper studies the greenho...
Article
Actions for increasing the renewable share in the energy supply and improving both production and end-use energy efficiency are often built into the regional level sustainability targets. Because of this, many local stakeholders such as local governments, energy producers and distributors, industry, and public and private sector operators require i...
Article
Energy costs typically dominate the life-cycle costs of centrifugal compressors used in various industrial and municipal processes, making the compressor an attractive target for energy efficiency improvements. This study considers the achievable energy savings of using three different diffuser types in a centrifugal compressor supporting a typical...
Article
In this paper, limiting factors for increased use of biomethane as a transportation fuel are studied. The aim of this research is to recognize and estimate the limiting factors for biomethane utilization in the transportation sector. The limiting factors are studied by using calculation models from Life cycle perspective and literature reviews. Acc...
Article
This paper examines the carbon footprint of renewable diesel (RD) production from palm oil, jatropha oil and rapeseed oil. Greenhouse gas (GHG) emissions from land use change (LUC), feedstock cultivation processes, and RD production and delivery are studied from a life-cycle assessment perspective. The goal of the paper is to calculate the carbon f...
Article
Employing a life-cycle assessment approach, this paper studies greenhouse gas (GHG) emissions resulting from biomethane used as transportation fuel. It focuses on both GHG allocation methodologies and uncertainties regarding GHG emissions from biomethane. The goal is to calculate GHG emissions of two types of biomethane used in transportation: that...
Article
For the estimation of greenhouse gas emissions from waste incineration it is essential to know the share of the renewable energy content of the combusted waste. The composition and heating value information is generally available, but the renewable energy share or heating values of different fractions of waste have rarely been determined. In this s...
Conference Paper
Full-text available
The aim of the paper is to carry out an analysis on socioeconomic risks and benefits of biofuel production on different stages of biofuel production chain. Biofuels have gained increasing attention as an alternative to fossil fuels and as a potential way to reduce the greenhouse gas (GHG) emissions while contributing rural development in developing...
Article
Full-text available
The publication summarises the results and conclusions of the research project Advanced Solutions for Recycling of Complex and New Materials. The aim of the project has been to create an understanding of the future development needs of waste recycling and management by conducting an in-depth analysis of five selected waste value chains.The chains a...

Two scenarios wer...
Article
The results of life cycle assessment of five different energy recovery-based waste management system options are presented. The system options were designed for the city of Kaunas, Lithuania. The Kaunas model was formed according to the Simple Integrated System Management concept developed at Lappeenranta University of Technology. CML2001 was selec...
Article
The paper presents the MEFLO ranking method and the Simple Integrated System Management (SISMan) concept for assessing the feasibility of integrated energy and Waste Management System (WMS) alternatives. The MEFLO method is based on dividing the decision-making process into five modules, including mass, energy and financial flows, legislative crite...
Article
The SISMan (Simple Integrated System Management) decision-aid model is introduced in this paper. The SISMan model is used in a demonstration of evaluating the viability of adding an Energy-from-Waste (EfW) plant to an existing municipal energy supply system. The integrated system utilizes co-generation in heat and electricity production. The evalua...
Article
A decision-support model for determining the feasibility of a planned energy-from-waste (EfW) investment for an integrated waste management and energy supply system is presented. The aim is to present an easy-to-understand, inexpensive and fast-to-use tool to decision-makers for modelling and evaluating different kinds of processes. Special emphasi...
Article
Full-text available
The total consumption of plastics in Western Europe was approximately 39.7 million tonnes in 2003, which means about 98 kg/person, and the amount has been increasing. The use of plastic materials has increased also in agriculture. Finnish agriculture produces about 12 000 tonnes of plastic waste in a year. The largest fraction is the films of silag...
Article
Full-text available
Waste management is being updated and developed in Lithuania to meet the EU standards and the requirements set by the economic growth of the country. The guidelines to this development are set in the revised National Waste Management Plan. Also the energy production and supply methods and systems are under serious consideration, mostly due to the f...
Article
The significance of the Gulf of Finland, which is p art of the B altic Sea, as an oil transport route has increased rapidly in recent years. Approximately 140 million tonnes of oil was transported through the Gulf of Finland in the year 2006. The amount of transport has doubled in a few years. At the same time, the accident risk has increased. The...
