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 ...
Aerobic biodegradation of butanol and gasoline blends
(Pergamon-Elsevier B.V. Ltd, 2009-09-01)
This work aimed to assess the aerobic biodegradation of butanol/gasoline, blends (5; 10; 15 and 20% v/v), being the latter compared to the ethanol/gasoline blend (20% v/v). Two experimental techniques were employed, namely ...
Biodegradation of blend films in soil and soil with chorume. I. PVC/PCL
(Research Journal Biotechnology, 2007-11-01)
Blends of synthetic and biodegradable polymers can be important in attaining material plastic degradation in the environment. Biodegradation using soil and chorume (liquid waste from landfill) microorganisms is a promising ...
Biodegradation of the Films of PP, PHBV and Its Blend in Soil
(Springer/plenum Publishers, 2009-12-01)
Films of poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV) and poly(propylene) (PP), PP/PHBV (4:1), blends were prepared by melt-pressing and investigated with respect to their microbial degradation in soil after 120 days. ...
Biodegradation of blend films PVA/PVC, PVA/PCL in soil and soil with landfill leachate
(Brazilian Archives of Biology and Technology, 2011-12-01)
This study investigated the biodegradation of blends films of poly(vinyl alcohol)/poly(vinyl chloride) (PVA/PVC) and poly(vinyl alcohol)/poly(caprolactone) (PVA/PCL) blends films prepared with dimethylformamide under a ...
LIGNOSULFONATE BIODEGRADATION BY CHRYSONILIA-SITOPHILA
