Cultured bacteria addition is one of the technologies used for odor control and FOG (fat, oil, and grease) removal in wastewater collection systems. This study investigated the efficiency of bacterial addition on wastewater odor control by conducting a set of full scale trials in a 60,000 cubic meter per day system for a period of two years. The objectives of this study were: (i) to identify factors that could impact wastewater treatment plant (WWTP) operations due to the effect of bacterial addition in the collection system, (ii) to estimate/understand the level of those impacts, and (iii) to present some interesting findings from the completed case study. The plant operation data before and during the bacterial addition were reviewed. The application of the cultured bacteria presented in the study was found to have significant impacts on the operation of the WWTP in terms of influent biological oxygen demand (BOD) and total suspended solids (TSS) loading, primary settling, sludge production, energy use, dissolved sulfides concentration, and methane production.

Each year, a large amount of waste paper (WP) is generated in Japan, and due to the change in lifestyle with the COVID-19 pandemic, the WP collection and recycling system in Japan faces new challenges. Although the government of Japan has installed WP collection systems, the efficiency of these traditional WP collection systems is too low, and this causes inconvenience to the governments, residents, and other stakeholders. On the other hand, some recycling companies in Japan are trying to establish a nontraditional WP collection system by setting their own WP collection stations in cooperative supermarkets. Yet, the efficiency of this new system has not been clarified. This research aims to investigate the current status, operational characteristics, and the role of recycling companies’ WP collection stations in the Japanese WP collection system. By performing trade area analysis and stepwise OLS regression, this research will evaluate WP collection stations’ efficiency. Moreover, this research will also discuss how the new WP collection system improves WP collection efficiency and residents’ convenience. The results show that WP collection stations efficiency is particularly high in large supermarkets with many parking spaces and long business hours, as well as in areas with many families with children. Recycling companies’ WP collection system could create a system, which can satisfy resident, government, and recycling company interests at the same time.

Wineyard pruning utilization for energy purpose is not only a theoretical possibility, the machine background has also been developed. Economic- and environmental experimentations has made by specialists and they seek to developed the best practice in logistics suitable for local conditions and they propagate the results for the potential users. Nevertheless, the utilization does not seem to be typical in Hungary and some other wine-grower countries. For example, in Hungary the additional energy from vineyard pruning eventuates – tillage, nutrient supply; – phy+tosanitary, environmental pollution; – energy management and economic questions. In Hungary the most important problem is practice of the vineyard pruning utilization were mentioned by the users is the establishment of collection system and the high logistic costs as Marczinkó (2007) experiences confirm this. As I experienced in practice, the winegrowers are uninterested in utilization. Most of them burn it at the end of the vineyard in many cases without considering of the relevant statutory prohibition. As my own several years expriment shows at Mátra wine region it is not the technical background which causes the failure. We can use effectively balers or chippers for collection. The cost of chipping is 14 535–27 000 Ft per hectars with the introduced technologies on Mátra wine region. The cost of 1 GJ of heat production is 606–1125 Ft. We can substitute the fuel with vineyard pruning and it means approximately 115 000 Ft saving for a family household per year.

Abstract. Medical geography and medical cartography can be denoted as classical application domains for Geographical Information Systems (GISs). GISs can be applied to retrospective analysis (e.g., human population health analysis, medical infrastructure development and availability assessment, etc.), and to operative disaster detection and management (e.g., monitoring of epidemics development and infectious diseases spread). Nevertheless, GISs still not a daily-used instrument of medical administrations, especially on the city and municipality scales. In different regions of the world situation varies, however in general case GIS-based medical data accounting and management is the object of interest for researchers and national administrations operated on global and national scales. Our study is focused onto the investigation and design of the methodology and software prototype for GIS-based support of medical administration and planning on a city scale when accounting and controlling infectious diseases. The study area is the administrative territory of the St. Petersburg (Russia). The study is based upon the medical statistics data and data collection system of the St. Petersburg city. All the medical data used in the study are impersonalized accordingly to the Russian laws.

This study aims to get information about: 1) How is the implementation of digital zakat finance in Indonesia?; 2) Why do zakat institutions need the Internal Audit role in the implementation of digital finance zakat?. This study is motivated by the development of zakat collection systems such as digital zakat finance system that uses a digital platform. Along with the development of technology, the role of internal audit is also expected to be expanded to the aspect of information technology audit. Internal audit division faces several challenges regarding digital zakat finance. Internal audit division has to ensure the zakat institution already mitigate the significant risk related to digital zakat finance. This study is limited to the audit aspect related to zakat collection system in BAZNAS that used digital platforms such as bank transfer collection system and collection system that collaborated with e-commerce. To achieve the study’s aims, this study uses qualitative methods with literature study techniques that are reinforced by interviews.

This paper presents a method for optimizing the household waste collection system supported by Geographical Information System (GIS) tool for the sector 1of district El Bousten of Sfax commune, Tunisia. The ArcGIS Network Analyst based model is applied for the purpose of improving the collection process effectiveness, namely, the household collection bins’ reallocation along with the vehicles’ tour optimization procedure in terms of distance and time. Results indicated a reduction of 25, 83% in route and 21, 5 % in the time spent of collection along with fuel consumption savings. These findings show that GIS based model tends to exhibit significant improvements as to the collection and transportation system, therefore, to its economical and environmental costs.

Relevant Topic

Municipal waste management is a relevant topic these days, in its relation to sustainable and environmental concerns. Sorting waste fractions at home for a door-to-door collection system proves to positively affect the environmental impacts of waste management strategies both by reducing the amounts of the waste landfilled and by originating new circular economies. However, the environmental impact caused by both waste collection and transport, together with waste quality, should be carefully evaluated to assess the sustainability of such a collection system. In order to evaluate the logistic and environmental effectiveness of a newly implemented door-to-door collection system in Altamura, a mid-sized town in Southern Italy, a survey was designed and submitted to a sample of citizens. The results obtained from the 385 completed surveys show that the door-to-door collection of glass waste is inefficient since most of the designated bins remain partially filled and less frequently delivered; citizens are more motivated to adequately collect sorted waste fractions upon receiving information about the subsequent environmental benefits and outcomes of the fractions collected; a high percentage of people still use disposable items in their daily life. Possible changes to the weekly bins collection schedule have been proposed in order to have a more proficient and environmentally sustainable waste collection service in the town. The survey is part of a project aiming at developing a smart device to support users in home waste management.
