Production bio-Fertilizer, organic compost and biogas for smallholder agriculture

This paper proposes the development of a portable digester that uses recyclable materials in their composition, and which aims to minimize the costs of implementation for small rural producers and consequently help in preserving the environment, reducing carbon gas emissions under the Kyoto Protocol. Despite being a technology quite widespread in southern Brazil, the models proposed in the literature, still have high costs at the facility, making it infeasible to your installation to family agriculture. Is notorious, that investments in technology are needed, since the benefits to increase social equity and environmental quality. Innovation is to propose a biodigester that uses recyclable materials in its structure and can be moved to any location of the country estate. With this bio-digester at hand, will be carried out a survey of technology, in order to ascertain its effective to suit the reality of Paraibano and the benefits generated for family farming. Next you’ll be using a methane gas detection equipment, in order to follow the evolution of it. The result shows a quite versatile, inexpensive and very useful for family farming. However the biodigestor proposed is a product essential in improving the quality of life of the local community, since they propose to generate extra income, maximizing social equity and minimizing the negative impacts on nature.

COUNTING AND DISCLOSURE OF CARBON CREDITS: A CASE STUDY ON COMPANY SUZANO PAPEL E CELULOSE S.A.

Currently society is more present in subjects related environmental and socio-environmental issues, requiring of the government and organizations, cleaner politics, creative methods that reduce the impacts to the environment, since the business environment is seen as primarily responsible for these impacts, releasing through their activities gases that contribute to air pollution and exacerbate the greenhouse effect, such as carbon dioxide (CO2 ), raising the temperature of the planet. The principal objective of this work was to detect and calculate the carbon credits generated by the reforestation activity of the company Suzano Papel e Celulose S/A, using a quantitative method for estimating CO2 emissions avoided. In the methodological procedures used a descriptive study with a hypothetical deductive method, and a quantitative and qualitative approach to nature. Based on sustainability reporting, the data needed to obtain the results were documented. It was also possible horizontally and vertically analyze the main environmental indicators, verifying an increase in the indicator of emissions of greenhouse gases, and a reduction in harmful hazardous waste indicator. As for carbon credits, it can be affirmed that the company studied had thousands of eligible credits trading on the stock exchange in the years 2010, 2011 and 2012, but did not recognize these credits on their statements, failing to raise millions of dollars that could be invested in other social and environmental projects. Therefore, it is perceived by the results obtained, that this theme about carbon credits is of great importance and should be discussed in greater breadth and depth, both the government and regulatory bodies of accounting, should seek a parsimonious treatment that facilitates implementation of CDM and carbon credit transactions on the stock exchange.
