Composting represents an alternative for the management of the organic fraction from municipal waste. However, the adoption of compost made from municipal waste is not yet widespread across all European countries, including Italy. Being ‘professional’ (i.e., farmers and gardeners) and ‘hobbyists’ the most representative categories of compost buyers in Italy, this study investigated their attitude toward municipal waste compost adoption and their purchasing pattern, pointing out criticalities and strategies to promote a wider use of this kind of compost. For the two categories of users, frequency of use of different information, buying habits, opinions on marketing issues, and factors which encourage compost utilization were investigated. The ‘professionals’ and ‘hobbyists’ reported different purchasing behaviors in terms of quantity, frequency, and preferred packaging format. The capability of compost from municipal waste to improve soil characteristics and its low environmental impact were identified as the most significant aspects for users, while availability of economic subsidies was not a determining factor for municipal waste compost adoption. With regard to the information sources, the broader use of personal communication channels like peers’ suggestions may have influence on compost adoption pointing out how social influence can promote sustainable behavior and influence users’ purchasing choices.

AbstractAdopting quantitative corpus-based methods, this paper focuses on the alternative negative constructions in Korean, [anV] and [Vanhda]. Logistic regression analyses for a mixed-effects model were carried out on data drawn from the Sejong Korean Corpus. Certain features of the verb or adjective in negative constructions significantly affect the use of the two negative constructions. A relevant factor is register/medium (spoken or written), among other significant interactions of factors. Furthermore, the fact that frequency is consistent with other relevant factors, together with certain diachronic facts of Korean, supports the claim that frequency of use plays an important role in linguistic changes. Another finding is that, notwithstanding noticeable differences between spoken and written language, the factors influencing the use of the two negative constructions in Korean are largely similar in the spoken and written registers.

Soil acidification processes are the main factor influencing the distribution of different Al forms in forest soils. The intensity of these processes is given by different stand conditions and anthropic activity. This paper describes the influence of four selected stand factors on the distribution of basic soil characteristics and two Al forms in forest soils of the Jizerské hory Mts. Altitude, liming, soil type and forest cover type are studied as selected factors. Distribution of most soil characteristics in the organic horizon, including organically bound Al, is influenced by the altitude. Distribution of mobile Al form is mainly influenced by liming. In the mineral horizon, no decisive factor affecting the distribution of variables was found. Cartograms of spatial distribution of pH, mobile Al form and total Ca content documenting their spatial relationships are shown.

Thinking as a crisis area in the phenomenon of the declining traditionally Afrikaans �sister churches�. Since little can be done, humanly speaking, to address the numerous factors influencing the decline of churches, it is obvious that everything humanly possible must be done. Thinking plays a major role in ecclesiology. This article focuses on human thinking as crisis area and as variable in ecclesiology. Because thinking is the determining factor controlling human activities, it is necessary to transform and change thinking when imbalances appear under the microscope of the last command of Jesus. Through the Great Commission, the Christocentric paradigm is revealed which serves as a corrective guideline for the imbalances created by the institutionalistic (I-paradigm) or the spiritualistic (S-paradigm) paradigms. Appreciative Inquiry (AI) is rediscovered as Scripture-based approach regarding change in thinking and the resulting change in the ecclesiastic crisis area, thus focussing on a more complete obedience to the Great Commission and promoting the possibility of natural church growth.

The Circular Economy concept implies the re-design of existing production systems in agriculture, by promoting agricultural waste recycling. In an organic zucchini—lettuce rotation, two different agroecological tools were considered: biofertilizer and presence or absence of green manure (GM+ and GM−). In particular, we compared: (i) anaerobic digestate from cattle manure, co-composted with vegetable wastes, with the presence of GM (AD GM+); (ii) olive pomace compost, re-composted, with the presence of GM (OWC GM+); (iii) municipal waste compost with GM (MWC GM+); (iv) municipal waste compost without GM (MWC GM−). These materials were tested with a commercial organic fertilizer without GM (COF GM−) as a positive control. The objectives were: (i) assessing the environmental sustainability of biofertilizers through carbon footprint analysis by greenhouse gas—GHG—emissions; (ii) evaluating the agronomic performance on the vegetable rotation, by energy output assessment. The total carbon emissions of biofertilizers production was 63.9 and 67.0 kg of CO2 eq Mg−1 for AD and OWC, respectively. The co-composting and re-composting processes emitted 31.4 and 8.4 kg CO2 per Mg of compost, respectively. In AD the ventilation phase of composting accounted for 37.2% of total emissions. The total CO2 emission values for the two-crop cycles were the highest in COF GM− and the lowest in OWC GM+, due to different fertilizer sources. On the average of the treatments, the input that induced the highest CO2 emission was irrigation (37.9%). The energy output assessment for zucchini and lettuce highlighted similar performance for all the treatments. Our findings demonstrated the validity of the tested processes to recycle agro-industrial wastes, and the potential of agroecological practices (GM) to mitigate GHG emissions.

Depending on the origin, the compost produced may contain not only nutrients but also pollutants, such as heavy metals and persistent organic pollutants. It is very important to determine them in soil-improving substances, because persistent organic pollutants show environmental toxic, cancerogenic, mutagenic effects and do not decompose for a long time. The aim of this study was to determine seven polychlorinated biphenyls concentrations in different kinds of composts produced in Lithuania and to evaluate the appliance of these composts in agricultural land. First, before routine analysis was done a gas chromatography with electron-capture detector method was developed. In this study 145 samples of green waste, sewage sludge, cattle manure, food waste, mixed municipal waste, digestate and composts made from mixed municipal waste after mechanical–biological treatment were analysed. Obtained results show that 28% of investigated cattle manure composts (CMCs) and 10.5% of food waste composts (FWCs) were free from polychlorinated biphenyls. Other kinds of composts investigated in this study (green waste compost (GWC), sewage sludge compost (SSC), mixed municipal waste compost (MMWC), mixed municipal waste compost after mechanical biological treatment (MMWCABMT) and digestate (DIG)) were contaminated 100% with polychlorinated biphenyls. Despite the fact that polychlorinated biphenyls were forbidden 25 years ago, their concentration varied from 2.70 to 163.7 µg kg−1 in different kinds of composts produced in Lithuania. According to get an increasing average amount of Σ7 polychlorinated biphenyls, Lithuanian composts were distributed as follows CMC > GWC > DIG > FWC > SSC > MMWCABMT > MMWC.
