Tapioca Waste-Methyl Methacrylate Irradiation for Biodegradable Plastic Raw Materials

Microwaves and microbes turn household waste into biodegradable plastic

Zinc Sorption on Modified Waste Poly(methyl methacrylate)

The new one-pot hydrolysis-crosslinking reaction was used to synthesize a new, waste poly(methyl methacrylate) (PMMA)-based material for zinc(II) ions removal. The alkaline hydrolysis of PMMA in diethylene glycol diethyl ether was used to obtain polymer matrix and it was then crosslinked with Ca and Mg ions to obtain the sorbent. As a result, the macroporous materials were obtained with a yield...

Methyl methacrylate cranioplasty.

We conducted a prospective study in order to audit our experience of repairing cranial defects using Methyl methacrylate. This included a total of 49 patients undergoing cranioplasty using methyl methacrylate, of which 45 were males and 4 females. The age of patients at the time of surgery ranged from 16 to 40 years old, with an average of 24 years. Malays were the majority (67%), followed by C...

Further Notes about Biodegradable Plastic

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...

Mapping of the Use of Waste as Raw Materials for Biogas Production

Anthropic methane emissions can largely be prevented or minimized using technologies that are already available. One such technology is anaerobic digestion (AD), which is used commercially around the world, especially in Europe and the United States, where some challenging targets have been set to diversify the energy mix with more renewable energy. This foresight study was designed to identify...
