AbstractThis paper presents the development and adoption of a discrete event simulation model of a pig meat-packing plant located in Navarre (Spain). The simulation model was developed to represent all the tasks and pig meat cuts production performed in the plant and implemented in ExtendSim™ 9.2. The development was incremental as the whole model was made of different sub-models focused in different products as for example ham, ribbon or sirloin. The main utility of the proposed model was the economic assessment of pig meat processing and cutting production. Pietrain breed presented more homogeneity and a better performance than Large White breed at equal price of the same products. In addition, even the ham is the most important cut, the loin and the bacon showed the best relative economic value with 52–53 % and 44–45 %, respectively, depending on the breed.

Abstract This paper addresses a serious environmental concern in Chile: PM2.5 concentration, a health threat especially affecting the population living in the central and southern communes of Chile. Using housing data for 312 spatial units, along with interpolation techniques to predict air pollution for communes with missing information, we find that, on average, 1 μg/m3 increase in PM2.5 produces a decrease of 4.1 per cent in housing rental prices. These estimates also show an important upward bias in the estimated coefficient when the endogeneity of air pollution is not addressed. An average Chilean household would be willing to pay US$12.31 per month for a one-unit reduction in PM2.5 concentration. Similar monetary values have been found in previous studies for both México and Chile. As with PM2.5 concentration, the average marginal willingness to pay exhibits marked differences across communes. From these results, the study addresses some policy implications and proposes avenues for future research.

On the example of Russia’s Irkutsk region the problem of air basin pollution as a result of fires in technosphere objects is considered. Has been proved the necessity for assessment of air pollution as a result of fires, and importance of such assessment has been demonstrated. It has been noted that the ecological assessment of air pollution from fires, which are the sources of pollution, previously had not been calculated at regional level. The method for phased determination of burnt materials’ quantitative and qualitative characteristics has been proposed. As a result of fires effects monitoring in 2000–2015 have been determined average values of burnt materials’ mass. Taking into account specific indicators for the toxicants emission during combustion of different groups of materials, have been determined mass values for priority products of combustion, that has allowed perform subsequently the ecological and economic assessment of air pollution from fires in the region. It has been established that every year in the Irkutsk region the ecological and economic damage from air pollution by combustion products was on the average 5,73 million rubles.
