Economic evaluation of hazardous healthcare waste treatment systems
The cost estimation and assessment of healthcare waste treatment systems (HCWTSs) for preventing financial and environmental damage are essential. This work reports economic analyses of treatment of hazardous–infectious waste based on WHO approach in HCWTS
S
of 43 hospitals in Tehran, Iran. The waste generation rate for total hospital waste in 43 HCWTS
S
was 4.42 ± 2.77 kg/active-bed/day. The mean of chemical, sharps, infectious, and general wastes in 43 HCWTS
S
were 13.79 ± 19.71, 30.29 ± 37.46, 336.28 ± 291.31, and 539.6 ± 383.13 kg/day, respectively. Economic analyses proved that general hospitals spent 1.63 times more than specialized hospitals on treating hazardous–infectious waste per year. The annual cost of treating each kilogram of hazardous healthcare waste in studied HCWTS
S
was 0.3 dollars. A range of total annual costs in 43 HCWTS
S
was limited to 7.9–118 thousand dollars. The results of ANOVA test demonstrated that the age and performance levels of hospitals significantly affect the annual capital and operating costs, respectively. Hence, improving recycling knowledge and increasing source-separated recycling should be considered to control the costs in HCWTS
S
. The results of this work have implications for the hospital managers in especially developing countries to evaluate previously unknown economic analyses and policies and take action to control wasted costs in HCWTS

Impact of self-efficacy on food waste reduction and its consequences in the solid waste economy using Monte Carlo simulation
The share of food waste in waste management costs is important because food waste constitutes a significant portion of municipal solid waste. Although the quantity of food waste depends on the food culture and behavior of citizens, but the impact of citizens’ dietary behavior on solid waste management costs is a knowledge gap. In this study effect of improving self-efficacy in food management behavior at home on reducing municipal solid waste management costs in Iran was investigated. For this purpose, the proportion of food waste reduction and related financial implications in waste management costs due to change in five main effective factors was calculated based on a financial model and Monte Carlo simulation. Although the cost of food waste management was more than 127,000 USD/year, improving food management behavior due to women’s self-efficacy in different scenarios will lead to a reduction in waste production by 45% and reduction in food waste management costs by 5.9–35.7%. Efforts to increase knowledge and modify citizens’ attitudes, leading to improved household food management behavior, have an important impact on reducing municipal waste management costs. Therefore, educating citizens is essential, especially in developing regions that are facing increasing solid waste production rates.

The “6th R” of sustainability: Repurposing operating room waste for community benefit
Operating rooms contribute greatly to hospital waste and greenhouse gas production. Efforts to “green the operating room” have focused on the 5R's of sustainability: reduce, reuse, recycle, rethink, and research. We propose a “6th R” —repurposing— as simple yet effective means of addressing operating room waste.
Clean, non-reusable surgical supplies were collected from a satellite facility of a children's hospital during a six-week pilot program. Materials were catalogued and repurposed throughout the community. The potential financial benefits were estimated based upon the value of repurposed goods and savings from reduced waste disposal.
Over 960 items were collected during the 6-week pilot. Materials ranging from plastic trays to surgical towels were donated to organizations throughout the community. Approximate retail value of repurposed items was over $1200. When extrapolated to the entire hospital system, these repurposing efforts could account for over $50,000 in donations and $1300 in operational savings over a calendar year.
Repurposing unused surgical items provide environmental, societal, and financial benefits, all while promoting more sustainable healthcare systems.
•Operating rooms contribute the most to hospital waste and its environmental impact.•Repurposing unused surgical supplies is under-recognized but simple and effective.•Clean, non-reusable surgical supplies may be repurposed throughout the community.•These repurposing efforts lead to environmental, community, and financial benefits.

Households’ expenditures for solid waste management services: Influencing factors and deep insight
This study aims to evaluate the existing solid waste collection and management system available to households in Pakistan and to explore the factors affecting households’ cash payments for waste collection and disposal services. Robust least square regression is applied to household-level data from 16,155 households in the Pakistan Social Living Measurement Survey (PSLM) for 2019–2020. This method was chosen for its ability to handle outliers and provide more reliable estimates. On average, households pay PKR 214 (USD 1.01) per month for waste collection and disposal services. Households in Baluchistan and Khyber Pakhtunkhwa pay the highest amounts, while those in Sindh and Punjab pay less. Rural households pay more than urban households. Waste collection is primarily handled by private vans/carts, with doorstep collection being the most common method. The municipality’s role in waste collection at the doorstep is limited. Public bins and waste collection points are accessible to 83 percent of households, but their distant locations and infrequent emptying pose significant problems. These limitations highlight the need for improved municipal involvement and infrastructure. Results indicate that household income, education of the household head, age of the household head, gender of the household head, number of earners in the household, doorstep waste collection via private van/cart, availability of bins or waste collection points, distance from waste disposal facilities, bin or waste collection point clearance duration, house ownership, dwelling type, and number of rooms significantly affect households’ cash payments for waste collection services. To increase cash payments for waste collection services, waste management authorities should provide better and modern solid waste management systems. Upgrading existing systems can enhance households’ willingness to pay for these services.

Overfished ocean strategy : powering up innovation for a resource-deprived world
\" We are living amidst a remarkable transformation. The linear, throwaway economy of today--in which we extract resources, create products, use them, and throw them away like a cheap plastic fork--is rapidly coming to a close. We are, simply put, running out of things to mine and places to trash. A new economy is being born, one that takes this line and turns it into a circle. Resource scarcity--the overfished ocean--is the reality virtually every company is swimming in. Those managers who deeply understand and master this shift will be able to turn the new reality into disruptive innovation and remarkable competitive advantage. Overfished Ocean Strategy offers five essential principles for developing products and services for this new reality. A business owner herself, Nadya Zhexembayeva fills the book with examples of companies that are already successfully navigating the overfished ocean. Unlike less-farsighted companies, they are not making \"green\" products as a sideline for a niche market but rather have made dealing with resource scarcity the central, driving force of their entire strategy. As these innovators ride ahead of the wave, new products, new business models, new markets, and new profits follow. You can join them, or you can be left standing on the shore\"-- Provided by publisher.

Effects of supplementation with rice husk powder and rice bran on inflammatory factors in overweight and obese adults following an energy-restricted diet: a randomized controlled trial
PurposeOverweight and obesity are major public health concerns worldwide which are associated with a low-grade chronic inflammation. Dietary fiber as an important component of diet could be effective in controlling weight and inflammatory factors. The present study aimed to compare the effects of rice husk powder and rice bran on inflammatory factors along with an energy-restricted diet in overweight and obese adults.MethodsIn this randomized trial, 105 eligible individuals were assigned to one of the three energy-restricted diet groups receiving; rice bran (n = 35), rice husk powder (n = 35), and control group (n = 35) for 12 weeks. Demographic data, dietary intake, anthropometric indices and inflammatory factors (serum levels of IL-6 and hs-CRP) were measured at baseline and at the end of the study.ResultsWeight, BMI and waist circumference reduced significantly in all groups after 12 weeks of study (P < 0.01 for all). However, pre- and post-measure differences between groups were not significant. Moreover, serum levels of hs-CRP and IL-6 were not significantly different between participants in the rice bran or rice husk groups. However, the reduction in serum levels of hs-CRP in rice husk (mean change = − 0.14 ± 0.05 µg/ml) and rice bran (mean change = − 0.13 ± 0.03 µg/ml) was significantly higher when compared to the control group (mean change = − 0.03 ± 0.02 µg/ml) (P < 0.05 for both groups). The same pattern was found when changes in IL-6 serum levels of participants in rice husk (mean change = − 0.48 ± 0.11 pg/ml) and rice bran (mean change = − 0.57 ± 0.13 pg/ml) groups were compared to the control group (mean change= − 0.19 ± 0.07 pg/ml) (P < 0.05 for both groups).ConclusionThe results of this study showed positive effects of rice bran and rice husk powder supplementation, combined with an energy-restricted diet, on inflammatory markers among overweight and obese adults.
