“…Earlier studies by the author on the role of waste as a fuel in DH systems concern the existing waste incineration plant in the city of Linköping (Holmgren and Bartlett [21], investment in a waste incineration plant in the city of Skövde (Holmgren and Gebremedhin [22]) and also additional investment in Linköping (Holmgren and Henning [16]). The studies show that in Skövde, the introduction of a waste incineration plant is profitable and in Linköping, investment in extended capacity is also profitable.…”

“…The debate around waste incineration has shifted from being a problem with emissions to whether it is suitable when aiming at a sustainable society with high resource efficiency. This question will be analysed to a certain extent in the study, where energy recovery and material recovery are compared in an energy efficiency perspective (Holmgren and Henning [16]), described in Section 4.4.…”

Waste is widely used as a fuel in the Swedish district heating (DH) systems, thereby linking waste management and the energy system. This paper summarizes earlier studies by the author on the role of waste as a fuel in DH systems. The method used is case studies of three Swedish municipalities that utilise waste in their DH systems. Economic optimisations of the DH systems are made using the linear programming model MODEST, and environmental effects in terms of carbon dioxide emissions are assessed. It is economically advantageous to use waste as a fuel due to regulations in the waste management sector and high taxes on fossil fuels. There can be a conflict between combined heat and power (CHP) production in DH systems and waste incineration, since the latter can remove the heat sink for other CHP plants in combination with low electrical efficiency in waste incineration plants. CHP is the main measure to decrease carbon dioxide emissions in DH systems on the assumption that locally produced electricity replaces electricity in coal condensing plants. It can be difficult to design policy instruments for waste incineration due to conflicting goals for waste management and energy systems. To put costs on environmental effects, so called external costs, is one way to include them but the method has drawbacks, for example the limited range of environmental effects included. Comparing the energy efficiency of material recovery and energy recovery from waste incineration is one way to assess the resource efficiency of the waste treatment methods.

“…7). PLA can be easily recycled, because its wastes may be converted back to the lactide and again subjected to polymerisation (Holmgren and Henning, 2004). Easy biodegradability of PLA enables its numerous applications in medicine, for example for surgical sutures, pins, suture anchors, plates, screws, and intra-vascular stents, burn dressings and substrates and skin grafts (Ulery et al, 2011).…”

Efforts were made to demonstrate that in biorefineries it is possible to manufacture all the commodities required for maintaining human civilisation on the current level. Biorefineries are based on processing biomass resulting from photosynthesis. From sugars, oils and proteins, a variety of food, feed, nutrients, pharmaceuticals, polymers, chemicals and fuels can further be produced. Production in biorefineries must be based on a few rules to fulfil sustainable development: all raw materials are derived from biomass, all products are biodegradable and production methods are in accordance with the principles of Green Chemistry and Clean Technology. The paper presents a summary of state-of-the-art concerning biorefineries, production methods and product range of leading companies in the world that are already implemented. Potential risks caused by the development of biorefineries, such as: insecurities of food and feed production, uncontrolled changes in global production profiles, monocultures, eutrophication, etc., were also highlighted in this paper. It was stressed that the sustainable development is not only an alternative point of view but is our condition to survive.

“…In addition, there are studies involving technical, economic and environmental analysis in order to evaluate the potential energy production from MSW [26][27][28]. In the past ten years, the assessment of integration of WTE applications into existing energy systems has also been included in several studies [21,29].…”

Storing municipal solid waste (MSW) in landfills is the oldest and still the primary waste management strategy in many countries. Russia is the third largest methane (CH 4 ) emitter country after USA and China, representing 5% of total global CH 4 emissions from waste landfilling. Due to high economical growth, the amount of waste generated in Russia has risen sharply over the last ten years. However, waste management in Russia is mainly based on landfilling. In order to design an optimal MSW utilization system considering various aspects related to sustainable MSW management, a linear programming model was introduced for this research. The performance of the proposed MSW utilization system in the target area has been evaluated in light of energy, economic, and environmental (3Es) aspects, such as system net cost, annual energy generated from the waste, and the carbon dioxide (CO 2 ) emissions of the system. St. Petersburg city was considered as the target area for the present analysis. The results show that the introduction of the proposed MSW system with energy recovery from waste along with a high level of material recovery has energy, environmental and economic benefits compared to the conventional treatment system. This paper emphasizes the importance of introducing waste treatment methods as an alternative to landfilling, and to improve recycling activities in Russia.Keywords: sustainable waste management; municipal solid waste; waste-to-energy; system design; optimization; linear programming; Russia; St. Petersburg : net costs of each treatment facility (USD/year) p : unit price of by-product (USD/t or USD/GWh) q : waste material allocated to treatment facility (t/year) fr : fraction of residue production at treatment facility fr LFD : fraction of materials (waste and residues) allocated for landfill disposal fr WTE : fraction of waste allocated for energy production fr WTR OPEN ACCESS
