Metallic Magnesium (Mg) and its alloys are highly suitable for medical applications as biocompatible and biodegradable implant materials. Magnesium has mechanical properties similar to bone, stimulates bone regeneration, is an essential non-toxic element for the human body and degrades completely within the body environment. In consequence, magnesium is a promising candidate as implant material...

Biodegradable plastics has gained significant commercial interest in recent years as they are having similar properties to that of the synthetic plastic used now a days, they are completely bio-degradable, are produced from natural (microbial) sources and are biocompatible in human system. These properties make PHB as an ideal candidate for various applications in medical field. The present art...

Background and purpose - Delayed bone healing with non-union is a common problem. Further options to increase bone healing together with surgery are needed. We therefore evaluated a 1-dose single application of erythropoietin (EPO), applied either locally to the defect or systemically during surgery, in a critical-size rabbit long-bone defect. Material and methods - 19 New Zealand White rabbits...

Background The plastics derived from petrochemicals have many applications. However, public concern and environmental laws led to conservation policies and establish programs that stimulate the research and use of new products based on renewable resources. Polyhydroxyalkanoates (PHAs) are biopolymers synthesized by microorganisms under conditions of nutrient stress with similar properties to co...

BACKGROUND Poly(γ-glutamic acid) (γ-PGA) is a biopolymer with many useful properties making it applicable for instance in food and skin care industries, in wastewater treatment, in biodegradable plastics or in the pharmaceutical industry. γ-PGA is usually produced microbially by different Bacillus spp. The produced γ-PGA increases the viscosity of the fermentation broth. In case of shake flask ...

Reverte oxo-biodegradable additive masterbatch and bags are not compliant to the criteria stated in AS4736 which is an Australian Standard® Biodegradable plastics—Biodegradable plastics suitable for composting and other microbial treatment documents. Well Plastics UK are in the same opinion as the Oxo-biodegradable Plastics Association that bio-based is the wrong technology (reason is as attach...

The claims of environmental protection and the lack of petroleum resources provide a new opportunity for developing plastic materials derived from biopolymer resources. Starch is one of the most studied and promising raw materials for the production of biodegradable plastics, because starch is quite cheap, abundant, biodegradable and edible. Starch consists of two major types of molecules, prim...

Synthetic polymers are widely used both in food or commercial industry. Plastic, one of its products is known to be expanding with changing lifestyles and increasing population. However, it causes deleterious effects on the environment due to its non degrading nature. Burning of this plastic waste and burying of the plastics releases harmful toxic material which is a major pollutant in environm...

Degradabilities of four kinds of commercial biodegradable plastics (BPs), polyhydroxybutyrate and hydroxyvalerate (PHBV) plastic, polycaprolactone plastic (PCL), blend of starch and polyvinyl alcohol (SPVA) plastic and cellulose acetate (CA) plastic were investigated in waste landfill model reactors that were operated as anaerobically and aerobically. The application of forced aeration to the l...
