“…The replacing of non-renewable with renewable resources is a key item on several organizations, also it is the subject of many public and private debates. Thus, renewable resources have become an economically viable alternative to traditional materials [2][3][4] . They are very attractive materials as alternatives to fossil-based polymers, especially when used as large-scale commodity plastics.…”

Bio-based linear low-density polyethylene (green LLDPE) composites are used as electrical jackets/insulator for cables. Assessments of gamma-irradiation (Co-60) effects on these materials are of interest as they might be used in nuclear power plants (NPPs). Brazilian sugarcane juice-based green LLDPE composite electrical jackets were irradiated until 1000 kGy and analyzed for thermal stability and mechanical characteristics. Thermogravimetry analysis (TGA) showed increasing of pyrolysis activation energy (E a ) (under N 2 ) from 42.7 ± 4.2 kJ/mol in unirradiated samples to 72.8 ± 4.6 kJ/mol after 60 kGy dose, as resulted of radiation-induced effects. FTIR spectra evidenced radiation-induced formation of conjugated C=C bonds after 250 kGy dose. Tensile stress and Young modulus did not change significantly until 150 kGy dose, whereas elongation at break decreased and reached 50% at 91 kGy dose. These results suggest that green LLDPE might withstand radiation damage through a NPP operating life (~ 40 years).

The mode of disposal of waste and effluent from swine breeding constitutes an important practice for environmental compliance of farms. For the need to produce quality and sustainability deploy many ranchers have sought treatment systems process waste from pig farming. Brazil has been increasingly investing in research and implementation of techniques for treating these wastes. Thus, this paper aimed to present the advantages of manure treatment and utilization of animal by-products. The case study refers to a Cooperative Farming of Nova Mutum, MT. The farm currently contains more than 23,000 pigs and waste generated by this process, in addition to producing electricity, are used as biofertilizers in irrigation Eucalyptus after being treated in the digesters. Through empirical calculations it was found that the average biogas is 2,438 m³ per day, with a calorific value greater than 2,000 kWh / day or 60,000 kWh / month, number higher than 22,000 kWh / month currently generated, so the cooperative can increase the capacity of your generator if you want to produce more energy. This requires further study of the efficiency of the treatment and the quantity and quality of effluent produced.
