A considerable amount of food waste ends up in centralized treatment plants due to the lack of preventive measures, resulting in significant environmental impacts. Hospitality food waste management is even more resource-intensive because of animal by-products regulation. According to this regulation, companies must store and then consign waste to specific waste managers. The extensive need for transportation of high-moisture-content materials is the leading cause of the impact. Moreover, the management of category III animal by-products is costly for companies. A previous study has shown the economic benefits of decentralized animal by-product treatment by intensive composting in catering companies. Although the produced compost was characterized by exceptional quality parameters, it was phytotoxic. The investigation of hospitality waste management is scarcely discussed among scholars, and waste management on a regional scale is nearly absent. This study examines the regional management of hospitality food waste by exploiting the municipal waste management infrastructure and intensive composting at the source. The co-maturation experiment with animal by-products and municipal green waste primary composts showed that the phytotoxicity parameters of the cured compost were in the optimal range or below the thresholds (conductivity (1.1 mS cm−1), dissolved organic carbon (82 mg kg−1), and NH4+/NO3− ratio (0.0027)). Additionally, the amounts of total nitrogen, water-soluble nitrogen, and water-soluble phosphorus in the compost were rated as very high. Finally, inventory and environmental impact analysis of the current and planned management approaches showed a reduction in 12 of 18 impact categories.

The Impact

The university is considered one of the engines of growth in a local economy or its market area, since its direct contributions consist of 1) employment of faculty and staff, 2) services to students, and supply chain links vendors, all of which define the University’s Market area. Indirect contributions consist of those agents associated with the university in terms of community and civic events. Each of these activities represent economic benefits to their host communities and can be classified as the economic impact a university has on its local economy and whose spatial market area includes each of the above agents. In addition are the critical links to the University, which can be considered part of its Demand and Supply chain. This paper contributes to the field of Public/Private Impact Analysis, which is used to substantiate the social and economic benefits of cooperating for economic resources. We use Census data on Output of Goods and Services, Labor Income on Salaries, Wages and Benefits, Indirect State and Local Taxes, Property Tax Revenue, Population, and Inter-Industry to measure economic impact (Implan, 2016).

e18820 Background: Rituximab-abbs is an anti-CD20 monoclonal antibody and an important immuno-oncology agent for the treatment of B-cell malignancies NHL (diffuse large B-cell lymphoma [DLBCL] and follicular lymphoma [FL]) and CLL. It is also indicated for patients with RA, GPA, and MPA. Rituximab-abbs was the first rituximab biosimilar approved in the US and is expected to reduce drug acquisition costs. This budget impact model (BIM) estimated the impact of replacing a share of originator rituximab (IV-R-REF) use with rituximab-abbs (IV-R-BIOSIM) for NHL (DLBCL and FL), CLL, RA, GPA, and MPA. The objective was to project incremental annual cost differences between IV-R-BIOSIM and IV-R-REF for a hypothetical 1-million-member US healthcare insured (Medicare) population. Methods: An illustrative BIM estimated changes in 1-year drug and administration costs for an increased IV-R-BIOSIM uptake from 17.5% to 22.0%. Values for epidemiology, market share distribution, drug dosing, administration, and costs were derived from scientific literature, product labels, and publicly available cost resources. Dosing was based on a mean patient body surface area of 1.8 m2. Annual dose counts per patient were: 10 untreated FL with maintenance; 8 untreated FL (without maintenance), relapsed/refractory FL, or untreated DLBCL; 6 CLL, and 4 for RA, GPA, or MPA. All treatments were assumed to infuse over 3 hours. Drug acquisition and administration costs were from 2020 Average Sales Price pricing file and Centers for Medicare and Medicaid Services Physician Fee Schedule. Patient cost share was based on 2020 Medicare Part B 20% cost-share for office visits and drug products. Univariate sensitivity analyses were conducted. A scenario analysis was performed to project 2-year costs for extended FL maintenance treatment. Results: Estimated total annual plan incremental savings for a 1-million-member payer after the utilization shift were $312,379, equating to $0.31 per enrolled member per year (PMPY). Per-patient incremental drug cost savings with IV-R-BIOSIM for 1-year were $5,474–$12,924 (Table). The model was most sensitive to IV-R-REF cost and proportion of patients with RA. Conclusions: This analysis estimated annual savings of over $310,000 ($0.31 PMPY) for a 1-million-member US payer following a 4.5% utilization shift from IV-R-REF to IV-R-BIOSIM, demonstrating that IV-R-BIOSIM may confer considerable economic benefits vs originator rituximab.[Table: see text]

New Varieties

This study estimates potential economic impacts of developing drought- and shade-tolerant bermudagrass (Cynodon dactylon) turf varieties in five southern states: Texas, Florida, Georgia, Oklahoma, and North Carolina. First, estimates are provided for the market-level crop values of the newly developed two varieties for each state. Then, an economic impact analysis is conducted using an input–output model to assess additional output values (direct, indirect, and induced impacts), value added, and employment due to the new varieties. Our results indicate that the two new varieties would offer significant economic impacts for the central and eastern regions of the United States. Under the assumption of full adoption, the two new products would generate $142.4 million of total output, $91.3 million of value added, and 1258 new jobs. When a lower adoption rate is assumed at 20%, the expected economic impacts would generate $28.5 million of output, $18.3 million of value added, and 252 jobs in the region. Our findings quantify the potential economic benefits of development and adoption of new turfgrass varieties with desirable attributes for residential use. The findings suggest that researchers, producers, and policymakers continue their efforts to meet consumers’ needs, and in doing so, they will also reduce municipal water consumption in regions suited to bermudagrass varieties.

The Impact

Prescribed burning is an important management tool in the extensive pastoral lands in northern Australia. It can be used to influence grazing patterns, increase the nutritive value of pastures, reduce the density of woody shrubs and reduce the risk of damaging wildfires. The consequences of regional-scale prescribed burning on pasture availability and annual carrying capacities of pastoral properties in northern Australia were examined using EcoFire, a fire management program in the Kimberley Region of north-west Australia, as an example. Theoretical long-term carrying capacities of land systems, and fire scar imagery from years before (2004–06) and during EcoFire (2007–11) were used to model the impact of the program on the seasonality and extent of fire-induced losses in annual carrying capacity, and the likelihood of properties experiencing catastrophic losses in a given year. Over the 5 years that EcoFire has been running, it has resulted in a progressive reduction in the loss of annual carrying capacity caused by the burning of pasture, and shifted the season that annual carrying capacity is lost to fire from predominantly the late to the early dry season. Most notably, the established program has reduced the probability of experiencing catastrophic loss (defined here as >50% of annual carrying capacity removed due to fire) from 18 incidences to three incidences within a 3-year period. These outcomes have the potential to deliver economic benefits to pastoralists via increased annual carrying capacity and by improvements in pasture condition, provided stocking rates and pasture utilisation are managed carefully.

The Impact

A concerning issue with Economic Impact Analysis (EIA) is that many EIAs give results for one year, without being explicit about how long impacts are expected to last. New tourism attractions should not be assumed to provide continuing positive impacts into the future. For instance, the Giant Pandas at Adelaide Zoo generated a positive economic impact in their first year of residence (22% of a sample of tourists visited Adelaide “due to pandas,” additional tourism expenditure in the region was $27.7 million, with $2.3 to $4.6 million captured by the zoo); however, increased numbers visiting to see the pandas lasted only two years. Investment decision makers expected larger, longer-term economic benefits than eventuated, and the zoo experienced financial difficulties. This study provides advice for predictive EIA of new tourism attractions and prompts a call for tourism EIA studies to be explicit about the time period for which results are relevant.

Deforestation is induced by human activities, cascading into associated cost and economic benefits. The concepts, dimensions and, deforestation caused by deliberate human activities were extensively examined. The chapter also highlighted the rationale for deforestation, environmental dimension to deforestation and contributions of forestry and forest by products to livelihoods. The segmented cases and experiences to create awareness on the need to discourage deforestation were explored. While recognizing that forest provides useful support for majority of rural dwellers, the justification for forest protection is advocated. Some communities depend on forests for their main livelihood, and use medicinal therapies derived from indigenous plants found in the forest. Forest remains an important pool of biodiversity and deforestation must be avoided. The chapter conclude that awareness of the impact of deforestation by the citizenry should be encouraged and supported by policies.

This case study presents the results of assessments of the potential risk of pollution by food waste in different applied shipping scenarios. A four-step model was used to analyse the applied procedures. The first step of the study involved the identification of possible strategies for on-board food waste management. In the second step, physicochemical tests of visually selected greywater detected high contents of nutrients (NTotal ≤ 238 mg·L−1 and PTotal ≤ 71 mg·L−1). Daily nutrient content (DNC) calculations of different food waste management scenarios allowed us to estimate the highest emission value from the discharge of greywater mixed with shredded food waste in the third step. In the final stage of the study, the results obtained made it possible to qualitatively assess the impact of DNC load on food waste management methods in the Baltic Sea environment. This study highlights the potential risk of polluting the Baltic Sea with nutrients and other contaminants in various scenarios, which will impact the marine recovery process. The presented research helps to outline waste management approaches for the reduction of these risks.

Air quality plans must be demonstrated to be economically sustainable and environmentally effective. This paper presents a full cost–benefit and environmental analysis of a large regional air quality plan involving several different actions covering a large spectrum of fields, from domestic heating to passenger and freight transport, from electricity generation to agriculture. The impact of each action is analyzed looking at the possible energy savings, greenhouse gases (GHG) emission reductions, the improvement in air quality, and the consequent decrease in external costs, namely the reduced impact on population health. The analysis is performed by applying a flexible and fast computer tool (RIAT+) that allows for a rapid simulation of different pollutant emission scenario, to assess different air quality indices (AQIs) over a regional scale domain. The results show that, in most cases, the economic savings exceed the implementation costs and thus that these actions can be introduced in air quality plans for the domain under study. The reduced health and climate costs, though relevant in absolute terms, are, in general, only a fraction of the economic benefits of energy savings. This is not true for the measures acting on improvements in electricity generation, since a reduction in power plant emissions (generally with high stacks, far from populated areas) does not significantly impact the air quality inside the region. A shift in energy production to renewable sources can instead provide noticeable effects on GHG emissions. This research raises some interesting and general questions about the adequacy of the methodologies applied to attribute costs (and benefits) to actions, improving a variety of sectors that are different from the one in which the measures are applied here.
