PLA and Montmorilonite Nanocomposites: Properties, Biodegradation and Potential Toxicity
The concern related to solid waste increases efforts to develop products based on biodegradable materials. At present, PLA has one of the highest potentials among biopolyesters, particularly for packaging. However, its ...
Applied models to biodegradation kinetics of lubricant and vegetable oils in wastewater
(Elsevier B.V., 2009-04-01)
Bioremediation technologies are used in order to remove pollutants from the environment in a safe, economical and harmless way during the treatment of waste, especially with the use of techniques such as biodegradation. A ...
Biodegradability of diesel and biodiesel blends
The biodegradability of pure diesel and biodiesel and blends with different proportions of biodiesel (2% (commercial); 5% and 20%) was evaluated employing the respirometric method and the redox indicator 2,6-dichlorophenol ...
Biodegradability of PP/PHBV (70/30) blend films
This study aimed to investigate the biodegradation of polypropylene/ poly(hydroxybutyrate-co-hydroxyvalerate) (PP/PHBV) blend (70/30, w/w) films in soil, monitoring the evolution of CO2 using the respirometric method. The ...
Biodegradation and toxicological evaluation of lubricant oils
(Brazilian Archives of Biology and Technology, 2012-12-01)
The aim of this work was to compare different toxicity levels of lubricant oils. The tests were performed using the earthworm (Eisenia andrei), arugula seeds (Eruca sativa) and lettuce seeds (Lactuca sativa), with three ...
LIGNIN DEGRADATION DURING SOFTWOOD DECAYING BY THE ASCOMYCETE CHRYSONILIA-SITOPHILA
(Kluwer Academic PublDordrechtHolanda, 1995)
Considerations for the design of polymeric biodegradable products
(De GruyterBerlin, 2013)
Several biodegradable polymers are used in many products with short life cycles. The performance of a product is mostly conditioned by the materials selection and dimensioning. Strength, maximum strain and toughness will ...
Aerobic biodegradation of butanol and diesel oil blends
(Academic Journals, 2010-10-18)
This work aimed to evaluate the aerobic biodegradation of butanol/diesel oil blends (5, 10, 15, 20%, v/v) in comparison to the biodiesel/diesel oil blend (20%, v/v). Respirometric experiments simulating the contamination ...
Cross-linked soy protein as material for biodegradable films: Synthesis, characterization and biodegradation
The modification of soy protein isolate (SPI) with different amounts of a naturally occurring cross-linking agent (genipin, Gen) and glycerol used as plasticizer was carried out in this work. The films yielded were cast ...
