This fact has led to an increase in the generation of organic waste of urban, agricultural and livestock origin, which requires adequate management that allows the recycling of the waste generated. In this sense, composting can be a feasible treatment to recycle this waste, and, therefore, improve its properties for agricultural use. Thus, the objective of this study was to evaluate the effect of the type of manure during its co-composting with organic waste of municipal and agricultural origin from the northwest of the island of Gran Canaria, for the subsequent use of the compost obtained as organic amendment in soils or as a substrate for soilless cultivation. For this, three types of manure were used: chicken manure, goat manure and cow manure, which were subjected to a co-composting process mixing them with plant residues from municipal gardens and agricultural crop residues, in the following proportions (on fresh weight): 37.6% straw + 32.7% manure + 29.7% pruning. The composting system used was an open dynamic system of overturned rows, forming three trapezoidal piles 1.5 meters high ´ 2.5 meters wide and 16 meters long. During the composting process, the evolution of temperature, humidity and different physical-chemical and chemical parameters were studied, and the agricultural value, sanitation and maturity of the compost obtained were also evaluated. The results obtained showed that the three piles achieved adequate sanitation according to the thermal requirements established in the regulations (temperature ≥ 60°C for at least 7 days) and a final product or compost suitable for agricultural use was obtained. Key words: organic waste, compost, degradation of organic matter, agricultural quality, sanitation","PeriodicalId":424774,"journal":{"name":"Modern Environmental Science and Engineering","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133337451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is explained that in the international civil aviation system there are norms and recommended methods that guide the construction of the airport infrastructure, to conserve and contribute to their environment in compensation of the social, economic, environmental and political transformation carried out. ASUR (aerodromes operations group) governed by Mexican aeronautical legislation, every 5 years presents its master development plan to contribute to the improvement of the environment and the prudent use of Cancun’s natural resources, thus, although the inhabitants have a contrary perception about the Cancun airport, it has become a sustainable infrastructure, which although it is true it modified the environment, nowadays it is the most important tourist bridge in the country leaving an economic development, social and cultural development superior to that of other airports. The above is concluded based on a mixed methodology that used the survey as an instrument for collecting information, statistics for data analysis and documentary information to provide legal support to the study.

For this purpose, an increasing stimulus experimental design was carried out with a control and three treatment groups: 3.68 fish/L (control), 4 fish/L (treatment 1), 4.5 fish/L (treatment 2) and 5 fish/L (treatment 3). Experimental fish were raised in recirculating aquaculture tanks for six months and fed a commercial pellet feed of 50% protein, the first and second month, and 45 % protein the four remaining months of the experiment. Fish biometry was performed monthly, taking a sample of 15 fish from each tank. The physico-chemical parameters of the rearing water were recorded fortnightly. The results revealed that fish growth was significantly (p < 0.05) affected by stocking density, positively. The highest growth performance in terms of final body weight and length was observed at a stocking density of 5 fish/L (treatment 3): 11.81 cm and 18.6 g. The highest total production (2.75 kg), net production (91.76 kg/m3), and the best feed conversion ratio (FCR): 1.49, were also noted in treatment 3.

With this definition in mind, a literature review was undertaken to investigate its contributions to stimulating sustainability in creative projects. Therefore, the descriptors “biophilia” and “sustainability” were used to search the Scopus database from 2003 to 2020. After applying multiple filters, 22 articles were identified covering the themes of urban green spaces, urban biodiversity, gardens, green infrastructures, management of space resources, sustainable policies and certifications, and community environmental projects. It was concluded that the application of biophilic principles stimulate new projects in design, architecture, and urbanism that provide opportunities for the “restoration” of the body and mind, and that can also converge with sustainable aspects.

A road trial was constructed with three subbase sections, comprising excavation waste (EW) and crushed concrete aggregate (RCA) plus a control section of EW with 20% dune sand (control). Visual inspection after 4 years in service revealed excellent performance with no surface defects or obvious differences between the different sections. The subbase surface was exposed and field-testing using lightweight deflectometer indicated very similar values for the unbound subbases of EW and the control section. The RCA subbase exhibited excellent performance due to self-hardening, providing much higher stiffness than the unbound subbases. The extracted unbound subbase materials satisfied the physical and mechanical requirements of the Qatar Construction Specifications with the exception of liquid limit, plastic limit, and sand equivalent, which are of less significance where the material is placed above the water table. The paper demonstrates that recycled aggregate can perform as well as conventional subbase materials and promotes their wider use to support sustainable development.

The current scenario that made face-to-face meetings between teachers and students impossible, due to the social isolation measures caused by the SARS COV 2 virus, boosted asynchronous teaching and paved the way for Education 4.0. Through the Constructivist Spiral methodology, this work proposes to reflect on the contributions of Environmental Education in asynchronous teaching for Early Childhood Education through the production of a pedagogical kit. As a result, it was identified that the promotion of an open environment for the participation of all those involved in the teaching-learning process favored an attitude committed to the collective construction of knowledge, showing that environmental “awareness” is a habit that needs to be built in together and serve as a guide for action, enhancing the transforming role of education.
