The proper disposal of solid waste is considered a challenge to many Brazilian municipalities that still dispose of their waste in controlled landfills and dumps, major causes of environmental liabilities. As the soil is one of the environmental components most affected by this practice, the objective of this work is to evaluate the vegetative development of sunflower and jack bean cultivated in soil with environmental liability arising from inadequate disposal of solid waste. Soil samples were collected from a deactivated dump located in the west of São Paulo and a control sample, in order to compare the development of species in different soils. The study was carried out in a greenhouse, from the Design of Randomized Blocks, with sixteen experimental plots, during 45 days. Soil fertility parameters and biomass production of the species were evaluated. The results were submitted to analysis of variance and the Tukey mean comparison test. There was a significant influence of solid waste on the availability of nutrients in the soil, which showed high levels of macronutrients and organic matter. The pig bean species stood out for its higher biomass production compared to sunflower, which indicates the possibility of using this species in the phytoremediation of this environmentally passive soil.

The urban climate changes, caused by intense urban densities, result in loss life quality. Therefore, it becomes increasingly necessary to know the dynamics climatic of a given region in search of strategies to promote socio-environmental quality. The present work aimed to analyze the temporal space variations of the urban climate and the implications of water availability and NDVI in urban heat islands. For this purpose, we adopt as case study the municipality of Palmas - Tocantins. In a first moment, the climatological characterization of the study area through the climatological water balance proposed by Thornthwaite and Mather (1955) was carried out. Then the terrestrial surface temperature (LST) and Normalized Difference Vegetation Index (NDVI) were calculated by means of multispectral images of the LANDSAT7 and LANDSAT8 satellites and GIS software. From the climatic water balance, it was possible to verify indices characteristic of the tropical climate as well as the climatic dynamics of the region. We observed small surface heat islands diagnosed by means of satellite imagery in the urban environment with a magnitude of up to 15 ° Celsius in relation to the nearby rural areas, especially in the drier periods. We also confirmed the importance of green areas in the mitigation of land temperatures.

Currently, the final destination of organic residues and aquatic macrophytes does not occur effectively, directly interfering with the environment and causing environmental problems. Therefore, the work aimed to reuse the organic waste from UNOESTE Campus 2, which comes from the university restaurant, urban cleaning and dairy cattle manure, as well as the aquatic macrophytes of the Cica dam in the municipality of President Prudent, using the vermicomposting technique in different treatments, analyzing the physical and chemical properties of the final compound and suggesting a better destination for such residues. Four treatments were carried out, with three repetitions each, namely: T1 (Dung, Organic waste), T2 (Aquatic Macrophyte, Dung, Organic waste), T3 (Urban cleaning waste, Dung, Organic waste) and T4 (Macrophyte, Waste urban cleaning, manure, organic waste).After collecting the compost, laboratory analyzes were carried out, which showed a significant increase in humidity when compared to the parametersof Normative Instruction SDA No. 25 of 2009. In the treatments carried out, T4 was highlighted by the breeding of earthworms. Therefore, through the execution of this work it was possible to confirm that the application of the vermicomposting technique is feasible for the treatment of organic waste.

The environmental diagnosis of the tributaries of the Lajeado Stream tributaries in Pirapozinho / SP is a study that will evaluate the characteristics of the natural environment, as well as the interactions and interferences caused by anthropogenic activities in the environment and the impacts resulting from these actions. This characterization will be done through visual on-site surveys, laboratory analysis and literature searches that allow a better understanding of the behavior of a watershed in face of external factors. In this sense, we evaluate procedures such as soil use and occupation, water quality, environmental valuation, development of vegetative areas, soil qualification, among other aspects. Thus, the interpretation of the quality of the natural resources raised and their interference will support an assessment of which identified impacts are likely to be mitigated in order to employ the necessary recovery and improvement technologies in the area.

– Improperly discarded solid waste has become a growing problem, proportional to population growth. There is a very worrying picture regarding the disposal of solid waste in the country. Poorly discarded waste often turns into environmental problems with costly and complex management. Therefore, the present project had the objective of quantifying the recyclable solid waste discarded in the vicinity of the Unoeste Campus II bus stops, in Presidente Prudente - SP, and thus propose an environmentally adequate collection and disposal. The work was done in two stages, the first being the collection of the residues at the selected points at specific times and the second being the separation and weighing of the same, synthesizing the results into tables in order to do the statistical design. The total weight of the collected residues in the morning, afternoon and night periods was 24.9 kg. According to the statistical projection, in one year a total of 968.4 kg of waste would be inappropriately discarded in urban roads, thus requiring strategic collection points, as well as the environmental education of the population as a whole
