1. Partial replacement of wheat flour by pumpkin seed flour in the production of cupcakes filled with carob
Abstract Pumpkin seeds are considered waste and its composition has high protein content, being feasible for human consumption, also reducing costs in waste treatment. In this work we provided an alternative to reuse the wastes of pumpkin seed applied in cupcakes formulation as a complementary source to wheat flour. Four formulations with different proportio

2. Evaluation of nickel and copper catalysts in biogas reforming for hydrogen production in SOFC
ABSTRACT The solid oxide fuel cells (SOFC) enable the efficient generation of clean energy, fitting the current requirements of the growing demand for electricity and for the environment preservation. When powered with biogas (from digesters of municipal wastes), the SOFCs also contribute to reduce the environmental impact of these wastes. The most suitable

3. Methane production in anaerobic digestion of organic waste from Recife (Brazil) landfill: evaluation in refuse of diferent ages
This work focuses on monitoring the generation of biogas by biochemical methane potential (BMP) assays, commonly used to assess anaerobic biodegradability of solid and liquid wastes under controlled conditions. The experiment employed 5 g of substrate of both refuses (fresh and one-year-old wastes), digested with 250 mL of inoculum in 1 L flasks as bioreacto

5. Uso de materiais recicláveis na determinação gravimétrica de CO2 no ar ambiente e tratamento dos resíduos de laboratório gerados
An alternative system was tested for the determination of CO2 in air using recyclable materials. The results indicate that the proposed system allows for reliable, accurate, robust and efficient collection, comparable to the standard gravimetric method. Laboratory wastes are easily treated using a filtrate that can be discharged into the sewer and solids tha

6. Manejo do mofo branco (Sclerotinia sclerotiorum L.) em tomateiro industrial / Management of white mold (Sclerotinia sclerotiorumL.) in tomato industry
Brazil ranks ninth in the world production of tomato (Solanum esculentum L.), while much of this production is destined for processing industries. The added value obtained with the fruit processing endorses this species as the vegetable with the greatest economic importance in the Cerrado region of Brazil, where the State of Goiás stands out as the largest

8. Disposição de lodo adensado de ETA em ETE com tratamento primário quimicamente assistido / Thickened water treatment sludge disposal in a wastewater treatment presenting a chemically enhanced primary treatment
Treatment systems, even for water potabilization or to reduce the amount of pollutants in wastewater, include physical, chemical and biological processes, and waste generation are inherent to water or sewage treatment plants. Solid waste generated in water treatment plants have inorganic characteristic, being removed from raw water by chemical and physical p

9. Estudo dos lixiviados das frações do aterro sanitário de São Carlos - SP por meio da caracterização físico-química / Study from de leachate of fractions from São Carlos landfill - SP through the physicochemical characterization
This work aimed to determine the stages of the decomposition of the waste disposed in São Carlos - SP landfill fractions through the study of the characteristics of the generated leachate. Samples were collected from the older area of the landfill (closed 10 years ago), and also from the first, second and third new built areas (garbage is still being dumped

10. Avaliação de diferentes inóculos na digestão anaeróbia da fração orgânica de resíduos sólidos domésticos
The process of anaerobic digestion of organic solid wastes can be optimized and accelerated by using methods that contribute to achieve a rapid and balanced start-up, such as the use of appropriate inocula. In this context, the present study aimed to analyze the potential application of bovine manure, pig manure and bovine rumen as inocula for the anaerobic

11. Caracterização dos resíduos esgotados de sistemas de tratamento individual de esgotos de Natal
In Natal still dominates the use of individual disposal systems for domestic sewage, once only 29% of the city has a sewarage system. Wastes that are accumulated in these individual treatment systems should be exhausted periodically, service provided by collector entrepreneurs. Some of these companies causing major damage to the environment. In Natal, only t

12. Análise da adição de resíduo oriundo do tratamento de esgotos em massa cerâmica utilizada para fabricação de telhas
Sludge of Wastewater Treatment Plants (WTPs) disposal is a problem for any municipality, for this reason the amount of sludge production is now a key issue in selecting treatment methods. It is necessary to investigate new applications for this waste type, due to the restrictions imposed by the environmental organs. The raw materials used in the Red Ceramic,
