“…On the other hand, negative values are GWP credits, and they characterise decrease in global production of GHG, thanks to the replacement of fossil fuels and primary raw materials. GWP calculation method for WtE plant is based on the work [15], where the author introduced inventory analysis. Here, GHG production is calculated similarly following the same assumptions and data.…”

“…Economic performance of a WtE plant treating RES as a mixture of several components was investigated in detail in [15]. In comparison to [16], where the economic model of WtE plant addressed one ton of RES, outcomes of [15] figured out contributions of individual components like paper, plastics, biowaste. A method of the marginal cost was applied.…”

“…While GHG production of aerobic and anaerobic treatment of separately collected biowaste are reviewed for comparison reasons, the contribution of biowaste component during thermal treatment of RES in WtE is investigated in detail to cope with uncertainty as mentioned above. An approach inspired by marginal cost [15] is developed, explained, and tested through a case study. Once the contribution of biowaste is known, the influence of the energy-effectiveness of the WtE plant on GHG burdens and credits related to biowaste only is also analysed.…”

Biowaste Treatment and Waste-To-Energy—Environmental Benefits

Biowaste represents a significant fraction of municipal solid waste (MSW). Its separate collection is considered as a useful measure to enhance waste management systems in both the developed and developing world. This paper aims to compare the environmental performance of three market-ready technologies currently used to treat biowaste—biowaste composting, fermentation, and biowaste incineration in waste-to-energy (WtE) plants as a component of residual municipal solid waste (RES). Global warming potential (GWP) was applied as an indicator and burdens related to the operation of facilities and credits obtained through the products were identified. The environmental performance of a WtE plant was investigated in detail using a model, implementing an approach similar to marginal-cost and revenues, which is a concept widely applied in economics. The results show that all of the treatment options offer an environmentally friendly treatment (their net GWP is negative). The environmental performance of a WtE plant is profoundly affected by its mode of its operation, i.e., type of energy exported. The concept producing environmental credits at the highest rate is co-incineration of biowaste in a strictly heat-oriented WtE plant. Anaerobic digestion plants treating biowaste by fermentation produce fewer credits, but approximately twice as more credits as WtE plants with power delivery only.

“…Several studies analyzed the issue of proportions between the various alternative ways of solving a given environmental problem (e.g. determining the optimal levels of international emission reduction [3], studying the abatement cost of carbon emissions in China [4], analyzing the reduction of the water footprint of the process of growing irrigated crops [5], assessing alternative solid waste management strategies [6], trying to introduce on-road pollution exposure (health cost) as an externality of traffic [7], studying the abatement costs of GHG emissions for ethanol and electricity derived from wood [8] or analyzing cost-efficient strategy for reducing PM 2.5 levels in the Tokyo metropolitan area [9]. To our knowledge, none of the analyzed papers touched upon the abatement cost of TSP emissions in context of different strategies for buildings envelope modernization and replacement of heating systems.…”

The problem of air quality is an urgent, and widely discussed political issue nowadays. Reducing air emissions is an expensive element of air quality management which can be reached by set of different independent means. One of the areas where solutions for improving air quality in cities can be found is the largest energy-consuming building sector, and related heating needs. The aim of the paper is to estimate the unit Total Suspended Particulates (TSP) abatement costs of building envelope modernization and replacement of heating systems with cleaner ones for buildings in the city of Krakow (Poland). Three, typical for Krakow, types of buildings are analyzed: a single-family house, a pre-war tenement house, and a block of flats. In all the options the base scenario is a coal heated building. The analyzed building’s upgrade includes different combinations of changes of heat source and insulation improvements. For each of the scenarios, the costs as well as the expected effects of unit TSP emission reduction were estimated for the whole city. This approach can support the decision making, planning and financial balancing of the most beneficial activities or estimation of the expected environmental effects.

“…Because marginal costs are directly related to production, marginal cost assessment can [20]: (i) motivate investments in infrastructure and equipment, improving efficiency and reducing operational costs; (ii) present variation of production costs; and (iii) reflect variations in the market prices of the resources. Marginal costs have been used to provide information about the operation of energy systems in the building sector [19], waste facilities [21], power plants (site model) [22], site utility systems focusing on steam production [23], and district heating facilities [20,24], to name a few examples. Quelhas et al [25] used marginal costs to analyze the influence of the various fuel networks (production, transportation and delivery of fossil fuels to the power plants) on the electric network.…”

The development of high-efficiency energy systems is a pressing issue nowadays, motivated by economic, environmental, and social aspects. Trigeneration systems allow for the rational use of energy by means of appropriate energy integration and provide greater operational flexibility, which is particularly interesting for buildings, often characterized by variable electricity, heating, and cooling demands. The benefits of trigeneration systems can be enhanced by the incorporation of thermal energy storage (TES), which decouples production and consumption. This paper analyses the operation of a simple trigeneration system including TES. The optimal operation is obtained by a linear programming model that minimizes the total variable cost. A thermoeconomic analysis based on marginal cost assessment of the internal flows and final products of the system is carried out, allowing to explain the optimal operation of the system and the role of the TES in achieving the optimal solution. The analysis unravels the marginal cost formation process, presenting a clear route from the final products obtained to the resources consumed. This information can aid the design of new plants, the retrofit of existing ones, and the operational management to achieve the minimum operational cost.
