A lot of waste from agriculture, industry, household and food waste is accumulated every year in Lithuania. Waste is polluting environment very intensively. From sanitarian point of view there can appear dangerous sources for people and other biological objects. The main method for utilisation of waste still remains landfilling. So as a huge problem appears operation of landfills, cumulation of leachate and biogas. The last years Vilnius city municipality directly changed the waste managing strategy. As it was estimated, food waste forms about 46,6 -56,6 % from total household waste amount. It was decided to turn this source from landfill to composting facilities, organise separate food waste collection from companies and habitants. The system was iniciated in 1997, but it develops very slowly. A private company "Chitinas" has started its work independently in neighbouring Vilnius city district. Two main unordinal methods were used for destruction of organic waste, both very usual in nature, but still rarely used in practice by farmers. Such methods are called in Lithuania "nontraditional farming". We estimate these methods as modem and perspective for organic waste destruction in big cities. With their help we can get ecologically safe, good natural fertilizers, without seeds and infections, having less nitrates and fosphates. Besides, we get an alternative product - material called "chitin", which could be chemically purified and has a perfect future in chemistry and medicine.

Proper management of food waste, a major component of municipal solid waste (MSW), is needed, especially in developing Asian countries where most MSW is disposed of in landfill sites without any pretreatment. Source separation can contribute to solving problems derived from the disposal of food waste. An organic waste source separation and collection programme has been operated in model areas in Hanoi, Vietnam, since 2007. This study proposed three key parameters (participation rate, proper separation rate and proper discharge rate) for behaviour related to source separation of household organic waste, and monitored the progress of the programme based on the physical composition of household waste sampled from 558 households in model programme areas of Hanoi. The results showed that 13.8% of 558 households separated organic waste, and 33.0% discharged mixed (unseparated) waste improperly. About 41.5% (by weight) of the waste collected as organic waste was contaminated by inorganic waste, and one-third of the waste disposed of as organic waste by separators was inorganic waste. We proposed six hypothetical future household behaviour scenarios to help local officials identify a final or midterm goal for the programme. We also suggested that the city government take further actions to increase the number of people participating in separating organic waste, improve the accuracy of separation and prevent non-separators from discharging mixed waste improperly.

The determinant factor identification of behavior considers as an important means in order to develop effective intevention towards household waste management in Indonesia. This study extended the Theory of Planned Behavior (TPB) by using the following construct: intention, attitude, subjective norm, perceive behavioral control, government intervention, environmental knowledge and awareness, as well as household planning and buying habit; to understand household waste management behavior from the ‘reduce-reuse-recycle’ point of view. The structural equation modeling (SEM) were used in this study and the result showed that the model accounted for relatively substantial amount (61.7%) of the variance in intention, with the attitude, subjective norm, and environmental knowledge and awareness emerge as significant predictor.  Above findings could be used by both governmental and non-governmental organization to formulate strategies to manage food waste at the household level.

Waste Handling

In a sustainable society based on an eco-cycling philosophy it is important to establish efficient waste recycling, as well as systems for re-use. Such systems include both material recovery and the extraction of bio-energy and nutrients using natural ecological techniques. In order to save energy and reduce transportation, which accounts for more than 60 % of the waste handling costs, it is essential to develop small-scale and local systems for the recovery of nutrients from waste products. The organic waste is an important resource of nutrients and should therefore be recycled and put back into the eco-cycling system. Every year in Sweden approximately 2,5 million tons of organic waste is not recycled, but instead incinerated or landfilled (Naturvardsverket, 1996). From an eco-cycling point of view the organic waste should not be landfilled as most of the environmental problems during the lifetime of a landfill is shown to be connected to the organic waste. Landfill gaz, leachate, odours and hygienic problems are all a result from landfilled organic waste, which instead ought to be composed or digested (Naturvardsverket, 1996). Investigations have shown that over 75 % of mixed solid household waste is biologically degradable and that nearly 50 % can be composted and re-used as a nutritious top-soil additive. Therefore, a recent Directive from the European Community prescribes that at least 75 % of the household waste in Europe shall be recycled and re-used by year 2005.

AbstractTo tap the organic waste generated onboard cruise ships is a very promising approach to reduce their adverse impact on the maritime environment. Biogas produced by means of onboard anaerobic digestion offers a complementary energy source for ships’ operation. This report comprises a detailed presentation of the results gained from comprehensive investigations on the gas yield from onboard substrates such as food waste, sewage sludge and screening solids. Each person onboard generates a total average of about 9 kg of organic waste per day. The performed analyses of substrates and anaerobic digestion tests revealed an accumulated methane yield of around 159 L per person per day. The anaerobic co-digestion of sewage sludge and food waste (50:50 VS) emerged as particularly effective and led to an increased biogas yield by 24%, compared to the mono-fermentation. In the best case, onboard biogas production can provide an energetic output of 82 W/P, on average covering 3.3 to 4.1% of the total energy demand of a cruise ship.

North America is a big consumer and consequently a big producer of waste. For the purpose of this project, we were primarily interested in collecting information in North America, focusing on Quebec primarily. The main research question was risen up during the fieldwork and assistance with the Canadian company. It clearly presents the enterprise readiness for obtaining a smart solution on organic/food waste problem. It is believed, how organic/food waste can be a resource of a high value. There is a capacity of creating a new path, where organic/food waste could become the important as plant/field nutrient supply. The circular approach to organic waste management is urgently needed in a way how the organic waste should be reduced and returned as productive resource input into our economy. The paper presents a new value towards a sustainability process that Canada is building at the moment. It represents the innovative approach, which is highly accepted in some cities in Quebec with the obtained pilot projects and excellent results. This paper is not only a simple research paper, but it is also the very important original innovative document which can be highly used on the level of each municipality, region and federal level.

AbstractIntroduction: In this article, we want to point out what kind of pedagogical and didactic change is being recorded in Slovakia’s education system and we will point out where it could go and develop to achieve positive results. This article is one of the upcoming outputs in the form of paper and study on the provision of structured, analytical and critical thinking (SAC). In the article, it is shown how the situation has changed and how we perceive the attitude of students during the educational process. Next, it is described current problems and inadequacies in the educational process and define how to use a change of thinking to increase motivation and improve access to knowledge.Purpose: In general, there is a consensus that it is important for teachers to be able to guide their students to problem-solving skills (Aktaş & Ünlü, 2013). It is pointed out that, with the right educational tools, such skills can be stimulated, developed and improved (Jordaan & Jordaan, 2005). This article is designed for all levels of education, but we are mostly concerned with educating future educators.Methods: In this paper, there are described methods that can help to improve the quality of thinking of students and thus increase the level of thinking of the whole society. This article take inspiration from important historical personalities as well as relevant current personalities in their professions. Critical, analytical and creative thinking, also based on logical and structured thinking, is our main method of our educational process.Conclusion: In conclusion, it is pointed out the need to develop SAC as a whole. It is important for the general publica to have better skills in SAC, for example, from the point of view of cognitive mistakes in experts, in the field of political literacy, recognition of misinformation and a better general awareness of rational thinking. As can be seen, SAC is not only about education, but it also closely affects society as a whole. It can thus influence the operation of the company, prevent the development of the first-class solutions offered and raise the whole company to a higher level.

AbstractWhile urban indoor farming is a fairly new phenomenon, there is a growing interest from producers, authorities and consumers alike. However, many assumptions are made, and expectations held, about urban indoor farming from a sustainability, food production and food provisioning point of view. These assumptions and expectations need to be tested and assessed. This study assessed greenhouse gas (GHG) emissions and a number of social aspects of a newly established indoor urban farm in Stockholm. The farm was the result of a project created by commercial, civil society and municipal actors with the aim to make use of unused urban space, create jobs and produce food. While lettuce grown on the indoor farm emitted more GHG than lettuce cultivated outdoors in Sweden, it was more climate friendly than imported lettuce in our comparison. Furthermore, the indoor farm created value for the actors involved and for the city district, albeit on a small scale. Many of the positive environmental and social features owed to the small scale of the indoor farm and the context in which it developed. Thus, when evaluating production systems like this one, we need to be cautious and refrain from extrapolating the results.

AbstractThis article reconstructs a conflict arising in a primary school in an inner-city district of Berlin. A pencil case of a newly enrolled girl with a migration background has been hidden. Is it a mobbing act? The teacher feels affected and reacts aggressively. In a longue monologue she collectively holds to account the children. Through her facial expressions, her gestures, her posture, and the prosody of her voice she communicates her moral point of view and her critique of the children. Emphatically she demands not to exclude but to integrate the girl. The interruption of the lesson indicates the importance of the conflict. To avoid the creation of a scapegoat the situation is taken seriously. Committed to the idea of a parenting instruction the teacher wants to secure recognition and appreciation among the children. The question arises if her strong emotional reaction is the adequate way to avoid the exclusion of the girl.

Starting Point

The absence of accurate information on the state of waste is a challenge to the solid waste management system in Syria. The local authorities commonly estimate the quantity of waste produced and its characterisation, which is the starting point for solid waste management planning. So, this paper aims to evaluate the generation and composition of household solid waste in Homs city, Syria. Also, the study presents factors influencing the waste generation rate and the waste composition. The study was carried out in 300 families from four zones in Homs city, and three sampling stages were conducted during the study duration, which started in July 2017 and ended in February 2019. The outcomes show that an average of 0.68 kg/per/day solid waste generated was calculated for the entire study area in Homs city. Also, the data analysis presents that organic waste constitutes the largest component in the waste mixture (69.1%) followed by plastic (10.6%), inert materials (8.7%), paper (4.6%), textile (2.5%), metal (1.2%), glass (1.1%), wood (0.6%), and hazardous materials (1.6%). The multiple linear regression results showed that the adjusted R2 value was found to be 0.557, 0.839, and 0.709 for the waste generation per capita, the daily household organic waste generation, and the daily household packaging waste generation, respectively. Also, according to Pearson’s coefficient values, a positive correlation was found between household waste generation and monthly income (r = 0.626), household size (r = 0.37), and age of the household head (r = 0.517), whereas a negative correlation was found between household waste generation and the education level of the household head (r = −0.649).
