“…Since that point, heat delivery reached its maximum. Annual GHG production does not change with increased WtE capacity considering power production is GHG neutral, see (Ferdan et al, 2018). The electricity production does not change and balance is approximately zero.…”

“…The Eq(6) deals with emissions, so it includes GHG contribution from WtE plants and landfilling, while the replacing of fossil fuels is considered. The methodology is described in more detail in (Ferdan et al, 2018). The last part, Eq(7) is the weighted multi-objective function which connects all mentioned objective functions Eq(3) -Eq(6).…”

The paper presents a new model for integration of circular economy strategies into the municipal solid waste management. The goals are to reduce the waste produced, recycle at the highest rate as possible (material recovery) and to use the resultant residual waste for energy recovery. Such a strategy utilizes both pricing and advertising principles in the mixed integer linear programming model while accounting two criterions-assessment of greenhouse gas (GHG) and cost minimization. The aim is to design the optimal waste management grid to suggest a sustainable economy with environmental concerns. The government, municipalities and/or authorized packaging company decide about the investments to the propagation of waste prevention and to advertising of waste recycling, while investors decide about new facility location and technological parameter. The availability of waste is projected in pricing method as well as in the location of the facility. The mathematical model will consider randomness in the form of waste production. The suggested non-linear functions of pricing and advertising are replaced by piecewise linear approximation to reduce computational complexity. The proposed multi-objective model is applied in a case study for the Czech Republic in the area of waste treatment infrastructure planning to support decision-making at the micro-regional level. The integration of circular economy principles, considering also the total amount of produced GHG, revealed the existing potential in waste prevention. On the other hand, the increase of recycling is limited, landfills are not supported and the energy recovery is preferred. However, the planning of the complex system relies on the decision-maker.

“…For comparison, the cost of plastics was 290 EUR/t. Following the same logic, Ferdan et al [17] presented an environmental impact of a WtE plant processing RES. The contribution of individual components to the overall performance of WtE was missing.…”

“…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. Burdens related to the performance of WtE are mainly subject to biowaste content in the input waste [17]. For example, the study [18] analysed fossil-based CO2 emissions from 10 WtE plants in Austria.…”

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.

“…As a result, large amounts of useless waste and spent product were generated. Since the processes used for recycling polyurethane foams, like mechanical recycling [24] or chemical depolymerization [25,26], are highly time-and energy-consuming [27], most of the wastes are discarded in landfills or directly burnt, leading to serious environmental issues [28]. However, the ease of availability of the raw materials helps to make waste PUFs a potential activated carbon adsorbent.…”

Highly Selective CO2 Capture on Waste Polyurethane Foam-Based Activated Carbon

et al. 2019

Low-cost activated carbons were prepared from waste polyurethane foam by physical activation with CO 2 for the first time and chemical activation with Ca(OH) 2 , NaOH, or KOH. The activation conditions were optimized to produce microporous carbons with high CO 2 adsorption capacity and CO 2 /N 2 selectivity. The sample prepared by physical activation showed CO 2 /N 2 selectivity of up to 24, much higher than that of chemical activation. This is mainly due to the narrower microporosity and the rich N content produced during the physical activation process. However, physical activation samples showed inferior textural properties compared to chemical activation samples and led to a lower CO 2 uptake of 3.37 mmol·g −1 at 273 K. Porous carbons obtained by chemical activation showed a high CO 2 uptake of 5.85 mmol·g −1 at 273 K, comparable to the optimum activated carbon materials prepared from other wastes. This is mainly attributed to large volumes of ultra-micropores (<1 nm) up to 0.212 cm 3 ·g −1 and a high surface area of 1360 m 2 ·g −1 . Furthermore, in consideration of the presence of fewer contaminants, lower weight losses of physical activation samples, and the excellent recyclability of both physical-and chemical-activated samples, the waste polyurethane foam-based carbon materials exhibited potential application prospects in CO 2 capture.Processes 2019, 7, 592 2 of 15 (Carbon Capture, Utilization and Storage) technologies are intended to reduce CO 2 emission, reaching the Paris Agreement targets is still a serious challenge. Nevertheless, in these techniques, adsorption is considered to be the approach with the most potential, since it involves simple operation and has low-cost and energy-saving benefits [8].Many adsorbents have been intensively studied for CO 2 capture, including zeolites [9], metal-organic frameworks [10], metallic oxide [11], graphene-based adsorbents [12], and porous carbon materials [13]. For future commercialization application, the selection of adsorbents is strongly dependent not only on CO 2 capture capacity but also the cost, including the availability of the raw materials, the preparation of the adsorbent, and the operating costs. Porous carbons (PCs) are considered to be the most competitive candidates due to their controlled pore structure, low cost, stable physicochemical properties, ease of chemical modification, and regeneration [14]. Micropore sizes smaller than 1 nm are beneficial to high-density CO 2 filling at ambient conditions [15,16]. In addition, a high surface area (>1000 m 2 ·g −1 ) and a rich nitrogen environment can improve the CO 2 adsorption capacity.The route of preparation, especially activation, will significantly affect the performance of CO 2 absorption. The porous carbons can be activated either by physical or chemical methods. Physical activation is usually achieved by carbonization in an inert atmosphere followed by oxidizing in CO 2 [17], steam [18], or air. In this way, activated carbons with a narrower pore size distribution can be obtained [19]. Gene...
