Analysis of a sustainable system for energy recovery from municipal waste in Croatia

Purpose – This paper seeks to focus on energy recovery from municipal solid waste (MSW) in Croatia. The state strategy is based on the mechanical and biological treatment of waste in the future waste management centers (WMC). Left over after the treatment is waste that can be used as fuel (e.g. RDF).Design/methodology/approach – Starting from the geographical distribution of waste generation (quantities and transport distances), taking into account the costs of collection, transfer and thermal treatment, recommendations on optimal number and size of the dedicated waste‐to‐energy (WtE) plants in Croatia as well as their potential locations are given. The opportunity of the cement industry to utilize ash from thermal treatment of waste in the process of the cement production and the RDF as a substitute fuel is also examined.Findings – By varying the number of WMCs, the minimal specific cost of waste collection of €33 is obtained, for maximal number of WMCs, which is 21. The optimal capacity of WtE facility ...

Current Account Balance and Export Performances: Evidence Based on New EU Countries

Abstract In this paper, we investigate whether the differences in the current account balance and export performances for a new EU countries are a result of exchange rate policies. The analysis shows that countries with a flexible exchange rate have better export performances and the current account balance in the pre-crisis period. The obtained results show that movements in the current account balance are mainly driven by domestic variables. In the countries with a flexible exchange rate, real and nominal depreciation affects export positively although the magnitude of these effects is tiny and limited to the crisis period. These results point to a higher significance of non-price competitiveness on export which should be a future research topic.

External imbalances in emerging and advanced European countries

Abstract This paper aims to explain some developments in current accounts across advanced and emerging European countries with a fixed exchange rate. Our main goal is to identify key factors affecting the external imbalances. This assessment of the cause of external imbalances will help us understand what has to be changed in European economies to recover the external balances going forward. We estimated a panel VAR model over the period 1999 to 2014 for a sample of 11 European countries that were split into two groups: advanced and emerging. The obtained results show that the real effective exchange rate has a negative effect on the current account balance in both groups of countries, although the effect is more pronounced in emerging than in advanced countries. Other variables such as the budget balance, economic growth, and output gap affect current account balance positively in advanced countries and negatively in emerging countries. Economic activity captured by output gap explains the highest portion of current account variations in emerging countries. In advanced countries, in addition to economic activity, the real exchange rate also plays a prominent role in current account imbalances.

Kyoto Protocol Objectives in Croatia Energy Planning

Croatia as an Annex I country of the United Nations Framework Convention on Climate Change (UNFCCC) and a country that has pledged in the Annex of the Kyoto Protocol to reduce its greenhouse gases (GHG) emissions by 5% from the pre-transition level by the budget period 2008-12, will have to envisage a new energy strategy. Compared to the energy consumption collapse in some transitional countries like Russia and Ukraine, Croatia has passed through a relatively limited long term reduction of GHG emissions since 1990 because of higher efficiency of its pre-transition economy. It is expected that in case of business as usual scenario it will breach the Kyoto target in 2003 since the demand for energy will be high, especially as the income continues to rise, especially in domestic use for heating, for transport and for electricity generation. Several scenarios of developing energy system are compared from the point of view of GHG emissions. Business as usual scenario covers the planned gasification of coastal Croatia. In the transport sector no GHG reduction compared to the business as usual scenario is expected, unless there are technology innovations on global automotive industry level. The energy sector that will most probably be the most influenced by the UNFCCC objectives is electricity generation. Several scenarios are compared. The cost-effective scenario expects a mixture of coal and gas fired power plants to be built to satisfy the new demand and to replace the old power plants that are being decommissioned. More Kyoto friendly scenario envisages avoiding the construction of the most of the future fossil fuel power plants, while decommissioning the old ones as planned, and is compared to the others from the GHG emissions point of view. The conclusion is that by measures tackling only electricity generation it will not be possible to keep GHG emission under the Kyoto target level.
