Food waste is a stream with multiple social, economic, and environmental implications, generated throughout all the life cycle stages of food. Among these stages, in developed and top touristic destination countries such as Greece, the role of the hospitality sector (i.e., restaurants, hotels, catering, etc.) in food waste generation is particularly significant. Against this background, the A2UFood project introduces a holistic management scheme in the municipality of Heraklion (Crete, Greece), in which all aspects of reduction, reuse, and recycling of food waste are included. The project seeks to implement the circular economy concept into daily practice, through a series of actions which preserve natural resources, support local communities, and create new value chains. More specifically, the holistic management scheme of the A2UFood project progresses towards three innovative directions: (i) Surplus food of high quality, from hotels and restaurants, will be redirected to people in need, through the establishment and operation of the “2nd opportunity” restaurant; (ii) Food waste from the hospitality sector will be directed to bioplastic production units; and iii. Home and community composting will be promoted and supported, as an option for the management of household food waste. To achieve the goals of the A2UFood project, an Information Campaign (“Food Save Share”), training workshops-seminars, and two smart tools (i.e., the Digital Food Waste Prevention Tool and the Resource Management Food Tool, for households and kitchen managers, respectively) have been developed.

Composting is considered an effective treatment option to eliminate or substantially reduce potential hazards relating to the recycling of sewage sludge (SS) on land. The variation of four major types of hazards (heavy metals, instability, pathogenic potential and antibiotic resistance) was studied during laboratory-scale composting of two mixtures of sludge and green waste (1:1 and 1:2 v/v). The heavy metal content of the final compost was governed by the initial contamination of SS, with the bulking agent ratio having practically no effect. The composts would meet the heavy metal standards of the United States of America (USA) and the European Union member states, but would fail the most stringent of them. A higher ratio of bulking agent led to a higher stabilisation rate, nitrogen retention and final degree of stability. A good level of sanitisation was achieved for both mixtures, despite the relatively low temperatures attained in the laboratory system. The antibiotic resistance was limited among the E. coli strains examined, but its occurrence was more frequent among the Enterococcus spp. strains. The type of antibiotics against which resistance was mainly detected indicates that this might not be acquired, thus, not posing a serious epidemiological risk through the land application of the SS derived composts.

Food waste is a stream that becomes increasingly important in terms of its prevention potential. There is a large number of behaviours that can be associated with food waste generation and the efforts towards food waste prevention. A questionnaire study was carried in order to study consumer behaviour related to food provision and wastage in Greece. Proper practices of the respondents that can prevent the generation of food waste were investigated using nine behavioural scales, which were defined on the basis of similar studies in other countries. A structured questionnaire was utilised in order to test those behaviours against the socio-demographic characteristics of respondents. The results of the study indicate that in terms of inferential statistical analysis, among the numerous variables examined, those that enhance food waste prevention are the involvement of the respondent in cooking, the annoyance towards food waste generation and the education level.

This chapter first discusses key aspects of waste prevention in a multidisciplinary context. It then defines the term “waste prevention” and discusses its importance in relation to sustainability. Next, the chapter presents the policy framework of the European Union (EU), the United States (U.S.), and selected countries that have taken important steps toward promoting waste prevention, presenting an analysis of waste prevention actions and initiatives applicable to production, supply, consumption, and the household for different key waste streams. The chapter specifically tackles food waste, packaging waste, nonpackaging paper waste, waste from electrical and electronic equipment (WEEE), and green waste. Finally, the chapter examines major barriers affecting waste prevention and reviews successful efforts of central and local authorities, businesses, consumers, and social enterprises in mitigating such negative barriers.

Home composting is a waste prevention measure related to the management of the household's food waste, garden trimmings, and other smaller organic household waste streams. Thus, home composting is an alternative way of exploitation of the “biomass” generated from the households. It is an alternative to centralized composting. Biomass utilization is explicitly stated as a principle of green chemistry. The aim of this paper is presentation of the results of a case study dealing with the life cycle environmental assessment of home composting of food waste in households in Greece. The results of the study indicate that home composting is environmentally preferable over the current organic waste management situation in Greece.

Waste prevention is the highest ranked priority in the European Waste Framework Directive. The aim of this paper is to present the design, development and main features of a web-based tool that enables local authorities to select and implement optimum waste prevention programmes for their local conditions and to prepare their Waste Prevention Plans. The aforementioned tool, namely the WASP-Tool, is implemented as a knowledge-based decision support system which extracts characteristics and features of the waste prevention strategy models and applies multicriteria evaluation techniques in order to facilitate decision making. It has been developed in Greek and reflects Greek and Cypriot data, context and waste prevention potential, to facilitate its use by local authorities and local administration. The application of the tool is demonstrated and its main features are presented.

Waste management planning requires reliable data regarding waste generation, affecting factors on waste generation and forecasts of waste quantities based on facts. In order to decrease the environmental impacts of waste management the choice of prevention plan as well as the treatment method must be based on the features of the waste that are produced in a specific area. Factors such as culture, economic development, climate, and energy sources have an impact on waste composition; composition influences the need of collecting waste more or less frequently of waste collection and disposition. The research question was to discover the main barriers concerning the compositional analysis in Insular Communities under warm climate conditions and the findings from this study enabled the main contents of a waste management plan to be established. These included advice to residents on waste minimisation, liaison with stakeholders and the expansion of kerbside recycling schemes.

Food waste is a waste stream with serious economic, environmental and social implications. The emphasis of the reported research is on the food waste generated by households in Greece. A structured questionnaire was utilised in order to identify the attitudes of the respondents and investigate the prevalence of certain behavioural good practices that can prevent the generation of food waste. The research, to our knowledge the first of its kind in Greece, took place in February and March 2012. Face-to-face interviews were employed, resulting to a total of 231 consumers fully completing the questionnaire. Results indicate that, based on self-reported behaviour, people in Greece have positive attitudes towards food waste prevention and that their habits are close to the good practices suggested in the literature for reducing food waste. For instance, most respondents do plan their food shopping in a multitude of ways and are very careful in their purchases of fresh food supplies. However, about 40% misunderstand the meaning of food date labels. The positive findings are strongly influenced by the severe recession experienced in the country, which makes consumers more conscious of their spending. Results may serve as a yardstick to further promote and establish food waste prevention behaviour at the household level on an environmental and social awareness basis that may outlast the economic crisis.

Surface visible–near infrared (NIR) reflectance of bare soil by remote sensing devices has been used to infer topsoil properties such as organic matter, soil texture, water content, salinity, and crop residue cover. Spectral mapping of soil properties can be ultimately used as a tool for the implementation of site-specific management practices at the field scale or for soil–landscape modeling at a regional scale. The accuracy of prediction of soil properties with satellite imagery is affected by conditions and properties of the soil surface, by radiometric and atmospheric effects, and by spatial and spectral resolutions. In this study, a high-resolution World View 2 image was used to map soil reflectance in three 10-ha fields of differing soil types and textures that were located in different sections of the east Thessaly Plain. Radiance data from four visible-NIR channels were extracted from the same coordinates that soil samples were taken at two soil depths within each field. Point radiance values were correlated to soil organic matter, total carbon (C) and nitrogen (N) contents, their isotopic composition, carbonate content, nitrate content, pH, electrical conductivity, and soil texture that were analyzed in the laboratory. Strong correlation coefficients emerged between green/NIR image reflectance and total soil N, organic matter, and carbonate content across the three fields in both soil depths. The greatest negative correlation coefficient (R2 = 0.77) was obtained between satellite NIR reflectance and soil N content. More data are needed to verify these relationships, but the results indicated the potential of high-resolution satellite imagery to quantify within-field and regional-scale variability of soil N and C in the Thessaly Plain.

The fate and effect of the herbicides linuron and metribuzin on the co-composting of sewage sludge and green waste were addressed in this work. The experiments were conducted in metal cubic containers of 1.0 m3 volume simulating a windrow composting system. A mixture of sludge and green waste was prepared at a ratio of 1:5 v/v. The mixture was split in four equal parts and the two herbicides were added, using a pressure sprayer, as sole or mixed pollutant in each of the three mixtures. The forth mixture was composted without any addition of herbicide, to serve as control. Temperature, physicochemical characteristics, herbicide concentration, carbon dioxide emission, methane emission and microbiological parameters were measured either daily or every time the mixtures were turned, for a period of 80 days. Both herbicides’ concentration decreased significantly resulting in removal efficiencies of 99.1–99.7% and 95.8–96.0% for linuron and metribuzin, respectively. Incubation of microbiologically inactive mixtures at a temperature schedule following the spontaneous temperature evolution in the composters resulted in very little (1–11%) decomposition for both herbicides. Comparison of the variation of physicochemical parameters and microbial populations during composting indicated that both herbicides did not affect the composting process.

In a bid to identify suitable microbial indicators of compost stability, the process evolution during windrow composting of poultry manure (PM), green waste (GW) and biowaste was studied. Treatments were monitored with regard to abiotic factors, respiration activity (determined using the SOUR test) and functional microflora. The composting process went through typical changes in temperature, moisture content and microbial properties, despite the inherent feedstock differences. Nitrobacter and pathogen indicators varied as a monotonous function of processing time. Some microbial groups have shown a potential to serve as fingerprints of the different process stages, but still they should be examined in context with respirometric tests and abiotic parameters. Respiration activity reflected well the process stage, verifying the value of respirometric tests to access compost stability. SOUR values below 1 mg O2/g VS/h were achieved for the PM and the GW compost.

Windrow composting of source-separated biowaste was studied in a pilot plant in Crete, with regard to abiotic factors, gas concentration in the pile and succession of functional microbial groups. The pH, C/N ratio and VS content, as well as the O2 and CO2 concentration, correlated well with composting time, indicating typical composting behaviour. Most of the microbial groups examined exhibited their highest counts towards the end of the thermophilic phase, with declining trends thereafter. The population of total mesophilic and thermophilic bacteria increased during the mild thermophilic phase and followed the temperature decline thereafter. Results on these microbial groups and fungi indicate that the timing of the thermophilic stage in the composting process, in addition to the peak temperature and duration of the stage, affects the microbial succession. Escherichia coli were detected for over 2 months of processing, in spite of the high temperatures achieved; only after about 3 months of composting did its population decline below the detection limit.
