“…Odorants emitted to the atmosphere may be of natural or anthropogenic origin. Sources of odor-forming substances, which are a side effect of human activity, are mainly the chemical industry [8], food industry [9], fuel industry [10], municipal sewage treatment plants [11,12], fragrance industry [13,14], composting facilities [15][16][17], municipal landfills [18,19] and swine farming and breeding [20][21][22]. The nature of odors generated by municipal waste management facilities depends on many factors, such as type of waste, method of storage, compost production techniques, etc.…”

“…The nature of odors generated by municipal waste management facilities depends on many factors, such as type of waste, method of storage, compost production techniques, etc. However, all these facilities emit pollutants of similar qualitative composition, and the odor nuisance is mainly related to the presence of the following compounds: disulfides, amines, sulfides, ammonia, thiols, alcohols, carboxylic acids, aldehydes, ketones, phenols, and aliphatic amines [13,19,[23][24][25][26][27][28][29][30][31][32][33][34][35]. The ranges of olfactory detection threshold and the perceived odor character for exemplary odorants are presented in Table 1.…”

Determination of Odor Air Quality Index (OAQII) Using Gas Sensor Matrix

This article presents a new way to determine odor nuisance based on the proposed odor air quality index (OAQII), using an instrumental method. This indicator relates the most important odor features, such as intensity, hedonic tone and odor concentration. The research was conducted at the compost screening yard of the municipal treatment plant in Central Poland, on which a self-constructed gas sensor array was placed. It consisted of five commercially available gas sensors: three metal oxide semiconductor (MOS) chemical sensors and two electrochemical ones. To calibrate and validate the matrix, odor concentrations were determined within the composting yard using the field olfactometry technique. Five mathematical models (e.g., multiple linear regression and principal component regression) were used as calibration methods. Two methods were used to extract signals from the matrix: maximum signal values from individual sensors and the logarithm of the ratio of the maximum signal to the sensor baseline. The developed models were used to determine the predicted odor concentrations. The selection of the optimal model was based on the compatibility with olfactometric measurements, taking the mean square error as a criterion and their accordance with the proposed OAQII. For the first method of extracting signals from the matrix, the best model was characterized by RMSE equal to 8.092 and consistency in indices at the level of 0.85. In the case of the logarithmic approach, these values were 4.220 and 0.98, respectively. The obtained results allow to conclude that gas sensor arrays can be successfully used for air quality monitoring; however, the key issues are data processing and the selection of an appropriate mathematical model.

“…Currently, only 14% of MSW in the world is recycled and reused, and 70% of MSW is dumped and landfilled [3]. In terms of safety and the environment, it is very important to deal with challenging obstacles such as dumping and landfill of solid waste [4]. The total volume of MSW in China is predicted to increase from 31.3 million tons in 1980 to 480 million tons by 2030 [5].…”

Globalization is bringing increased industrialization and municipal solid waste (MSW). This is a major concern in heavily populated areas. In order to reduce MSW generation, incineration is commonly used, resulting in two types of ashes: bottom and fly ash. Bottom ash is gathered at the incineration bed and is larger in mass than fly ash. To test the qualities of high-performance mortar, MSW-BA in three sizes (fine, medium, and coarse) was replaced with sand at three replacement levels of 10%, 20%, and 30%. The high-performance mortar integrating MSW-BA was tested for hardened density, mechanical properties such as compressive and flexural strength, resistance to NaOH solution, and heavy metal leaching. The substitution level of MSW-BA increased the hardened density of the mortar mixes. The volume change and residual strength of the mortar mixes were measured following exposure to the NaOH solution. Fine-particle mortar mixes shrank whereas medium- and coarse-particle mortar mixes expanded. The largest loss in flexural and compressive strength was recorded when 20% of sand was replaced with a fine fraction of MSW-BA. Heavy metals including cadmium and copper were not leached from MSW-BA combinations of any size. The minuscule amounts of lead and zinc discovered were well below acceptable limits. The present study illustrates the MSW-BA can be utilized as a substitute for sand in the development of high-performance mortar.

“…The OFMSW is the biggest fraction in the MSW, and its decomposition in the case of uncontrolled destination (e.g., in dumpsites) can create problems of processing, odour, biogas and leachate, leading to pollution problems and costly environmental restoration [32][33][34][35]. That is why it is essential to correctly dispose this waste fraction by directing it to a dedicated treatment: composting, anaerobic digestion, etc [36][37][38][39][40].…”

In low-income countries, the organic is the prevalent fraction of the municipal solid waste (MSW) and its decomposition can create problems with processing, odour, biogas and leachate. On the other side it is an important resource because rich in organic matter and nutrients, which can be properly recycled. Therefore, it is essential to correctly send the organic fraction to a dedicated collection and valorisation flow. Within the LimpaMOS MOÇambique project, which is taking place in the cities of Beira and Nampula, numerous Italian and Mozambican actors from the public, private and no-profit sectors are involved. The project is mainly co-financed by the Italian Agency for Development Cooperation. One of the objectives of the project is to strengthen the proper management, separation, valorisation and disposal of MSW. The composting process is a valid solution for the treatment of the organic fraction as it allows a substantial reduction in the volume of putrescible material stored in landfills, and at the same time it makes it possible to produce and sell a good quality soil conditioner. The research work carried out in this study focuses mainly on two aims: an analysis of the management of the Composting Centre (CeCom) which will be built in the city of Beira, and an investigation on the organic waste collection by local communities. In order to move the organic fraction further away from the urban context, a subsequent expansion of the input matrix of the CeCom is essential. The study wants to involve the city's second main market, some restaurants and the harbour canteen in the process of separating, collecting and managing the organic fraction. However, this expansion cannot take place without the creation of institutionalised, trained and remunerated groups of local workers.
