The conventional treatment by composting was carried out on manual aerated piles: 70% residue pruning/weeding (RPC) and 30% organic waste from the canteen (ROC); 50% RPC / 50% ROC, 30% RPC / 70% ROC. The mechanized system consisted of a reactor of 190 liters – 50% RPC / 50% ROC, with air injection from a compressor for 15 minutes daily. The parameters characterized and monitored were pH, organic matter, organic carbon, ash, nitrogen kjedahl and phosphorus. The temperature measurements were taken daily by a digital thermocouple (top, middle and base of the piles and reactor)... (Completo abstract click electronic access below)

Monitoramento das águas subterrâneas do aterro de resíduos da construção civil e inertes, no bairro Jd. Wenzel, em Rio Claro-SP

This work is proposed to evaluate the potential risk of an inert landfill in the city of Rio Claro (SP), and also suggest a source for the contamination. The study was proposed because it is known that there were legal technicalities greetings to guarantee the quality of groundwater. Given the requirements of the Environmental Company of São Paulo (CETESB) were installed monitoring wells in the area; sampled to groundwater and its contamination was found. In addition, we analyzed the main characteristics of the area, the arrangement and characteristics of the waste, the local geology and the hydrogeological system, so that I could find the source of contaminants, and predict the direction of dispersion even in groundwater. At the end of the work presents conclusions, recommendations and proposals for mitigating action

Análise das emissões de gases do efeito estufa na produção do milho através da fertilização por resíduos de biocombustível. Estudo de caso : Dedelow - Brandemburgo - Alemanha

The focus of this research study were gas exchange between soil and atmosphere of nitrous oxide (N2O) between different fertilization treatments Corn The research, conducted in the experimental field Dedelow - Brandenburg / Germany, analyzed three different fertilization treatments, aiming to quantify GHE emissions, to identify the influence of the residue of biogas in the release of these gases process in agricultural soils in search for a solution fertilization less harmful to the environment and the greenhouse effect , based on the comparison of three treatments: organic fertilization, mineral fertilization and no fertilization. It was found through the analysis of the measurements that the first was the one which issued N2O, showing that even though coming from the residue of biogas , when returned to the soil, it becomes harmful to the environment and global warming . The cultivation of energy crops can lower or raise the emissions of greenhouse gases, so it is necessary for further research on this question not only in Germany , where such research is in continuity, but also in Brazil, a pioneer in the introduction to his energy matrix of a biofuel produced from cane sugar

Viabilidade do aproveitamento de resíduos de madeira para produção de móveis

The need to use waste from wood processing industry grows due to environmental demands imposed by laws, so like the need to introduce more competitive products in the market (it means better quality and acceptable cost) who must submit by the rational use of raw material, usually turning waste to sub products, what adds higher value for that. To this research, specific case from Ribon Company, located on Camaçari, Bahia-Brazil, has been studied. It is a treated wood producer. Bulk of monthly wood logs there is 70 m3. Its yield is 71,43%, where bulk of generated waste is monthly 20m3. As an exploitation way from generated waste, it has been suggested some options like: erosion protection to specific areas, a wildlife shelter as an henhouse etc, recreational articles, coal, linings, treadmills. However this research will give focus to the furniture design made of waste. As a conclusion, there is very much need to assign new utilizations to that sub used materials, since there is significant amount to increase company’s productive yield

Aplicação do ciclo rankine orgânico alimentado termicamente pela queima da casca do arroz e resíduos de madeira

With the growing world energy demand mainly from developing countries like Brazil, Russia, India and China, the search for efficient sources of energy becomes a challenge for the coming years. Among the most widely used alternative sources, biomass is the one that grows in a more pronounced way. This study will assess the real possibility of having it as a heat source in an Organic Rankine Cycle, which employ heat transfer fluids as working fluids instead of water. From a regional data collection in agricultural production and their potential rice production and the resulting husk was defined as more appropriate. The availability of husks together with an amount of eucalyptus wood, provided by a company in the region on a monthly basis, were analyzed, and the low participation of the wood was discarded by the thermal contribution of little significance. Based on this, it was established the calorific value of fuel for thermodynamic calculations and the cycle to be used. It was then carried out the choice of working fluid from the literature and their availability in the library of software used for the simulations, the Engineering Equation Solver - ESS. The fluid most appropriate for the burning of biomass, Octamethyltrisiloxane (OMTS), was not included in the software and so the R227ea and R134a were selected. After the initial parameters modeling definition, as condensing temperature, efficiency and live steam conditions, the simulations were performed, and only the R227ea remained within the feasible thermodynamic and technological ranges. With this fluid the turbine power output was 265.7 [kW] for a scenario of 24 hours/day burning, 800.3 [kW] to biomass burning for 8 hours/day and 2134 [kW] for burning only 3 hours/day. The thermal efficiency of the cycle remained in the range of 6%, and for plants operating with the most... (Complete Abstract click eletronic access below)

Comportamento da temperatura da massa de resíduos aterrados em um aterro sanitário

In this paper we investigate the temperature variation of the mass of waste along the depth in a household waste landfill of Rio Claro - SP, São Paulo, having a climate characterized as Tropical Altitude. In this research, there were two holes in two distinct points of the landfill, with different depths and characteristics in order to fix several thermal sensors - RTDs - to record the temperature at predetermined depths. Overall, the results show the influence of temperature at depths of up to 3.0 meters (from the surface) and that it varies in a manner to stabilize at depths above 5.0 meters. The highest temperature obtained was approximately 37.5 ° C for a time of waste disposal of 7 to 10 years. The results showed the presence of organic matter (substrate) which resulted in elevated temperature resulting from biological activity

Restos, resíduos e impurezas para compor a poesia: o entrópico e o poético em Adília Lopes

A poesia de Adília Lopes merece nossa atenção crítica pela singularidade com que se recorta no atual panorama literário português. Em “Louvor do lixo”, por exemplo, poema contido em sua obra A mulher-a-dias (2002), é redimensionado o papel da poeta em um mundo marcado pela entropia e por formas desgastadas de sobrevivência. Operando com imagens alusivas ao cotidiano e dotando a linguagem poética de um funcionamento desestabilizador das convenções, Adília instiga no leitor questionamentos, não apenas sobre a subjetividade poética, como também sobre uma nova concepçãode lirismo, o qual inclui em seu fazer materiais imprevisíveis, desconcertantes. Nosso propósito é analisar como a autora promove tal desconcerto, por meio de procedimentos de construção presentes no poema mencionado. O gauchismo de Adília recupera um posicionamento transgressor que, embora já patente em poéticas de vanguarda do século XX, assume novas implicações ao gerar outros efeitos de sentido. A tradição cultural, o meio familiar, os valores poéticos, o erotismo são alguns dos aspectos que estão na mira da visão corrosiva da poeta, que não receia expor a si e à própria linguagem.
