I was getting all worked up about how our bodies are now full of microplastics and shit, and then i remembered i've got literal bimbo tits😆😆

Scientists in China have developed a biodegradable glass that aims to cut back on glass waste in landfills while reducing the need for energy-intensive recycling processes.
(If glass is easier to use again and maybe less expensive and energy intensive maybe glass will be a better alternative than plastic for certain situations?)

The breakthrough, spurred by the discovery of plastic-eating bugs at a Japanese dump, could help solve the global plastic pollution crisis
Greatest accident ever
The new research was spurred by the discovery in 2016 of the first bacterium that had naturally evolved to eat plastic, at a waste dump in Japan. Scientists have now revealed the detailed structure of the crucial enzyme produced by the bug.
The international team then tweaked the enzyme to see how it had evolved, but tests showed they had inadvertently made the molecule even better at breaking down the PET (polyethylene terephthalate) plastic used for soft drink bottles. “What actually turned out was we improved the enzyme, which was a bit of a shock,” said Prof John McGeehan, at the University of Portsmouth, UK, who led the research. “It’s great and a real finding.”
The mutant enzyme takes a few days to start breaking down the plastic – far faster than the centuries it takes in the oceans. But the researchers are optimistic this can be speeded up even further and become a viable large-scale process.
“What we are hoping to do is use this enzyme to turn this plastic back into its original components, so we can literally recycle it back to plastic,” said McGeehan. “It means we won’t need to dig up any more oil and, fundamentally, it should reduce the amount of plastic in the environment.”
About 1m plastic bottles are sold each minute around the globe and, with just 14% recycled, many end up in the oceans where they have polluted even the remotest parts, harming marine life and potentially people who eat seafood. “It is incredibly resistant to degradation. Some of those images are horrific,” said McGeehan. “It is one of these wonder materials that has been made a little bit too well.”
Plastics have been playing an important role in our lives since many years. Some significant characters of these polymers such as lightweight and durability make them an attractive material and they are largely being used in number of applications e.g. packaging and electrical insulations. These polymers can be molded into desired shapes which make them an excellent material for making pipes, sheets and packaging material. Toughness of plastic makes them an extremely resistant and inert material toward degradation as a result they are accumulating in terrestrial and marine ecosystem at a dangerous rate over the last few years. Attempts have been made to replace synthetic plastic material with bioplastics or plastic those are easily biodegraded. Biodegradation is a noninvasive technique used to degrade plastic material through action of microbes so that plastic contamination can be reduced and terrestrial and marine biota could be saved from hazardous effects of these polymers.

The substantial surge in waste entering our aquatic ecosystems poses one of the leading environmental hazards. With the Philippines ranked as the third-largest contributor of plastic into the ocean annually, efforts to mitigate this issue through biodegradable alternatives are crucial. This study assessed the polystyrene (PS) biodegradation capability of microorganisms from talabang tsinelas (Crassostrea iredalei) in Buguey Lagoon, Cagayan. Two distinct colonies, Pseudomonas aeruginosa and Enterobacter cloacae, were identified using the API 20E biochemical test kit for their potential in polymer degradation. SEM analysis confirmed substantial surface deterioration of PS films exposed to these strains, indicating microbial degradation. One-way ANOVA analysis revealed no significant difference in polystyrene degradation among the isolated microorganisms, as all p-values exceeded the 0.05 significance level. The F-value for days 15, 30, and 45 were 1.207892, 1.324312, 1.665196, 1.665196, respectively, with corresponding p-values of 0.362385 for day zero (0), 0.333897 for day fifteen (15), 0.265922 on day thirty (30), and 0.167041 for day forty-five (45). These results indicate that the weight loss of polystyrene over time did not significantly differ between P. aeruginosa and E. cloacae. Results of the SEM also revealed the ability of P. aeruginosa and E. cloacae, to degrade PS plastic. The PS film subjected to P. aeruginosa exhibited the most extensive surface deterioration. This was characterized by the formation of deep pits, significant increases in surface roughness, and the development of cracks. Conversely, the PS film exposed to E. cloacae exhibited minimal or lesser degree of surface degradation compared to P. aeruginosa.
The main goal of this research was to investigate the diversity of lignocellulolytic bacteria in the native soil of sugarcane trash and to assess their biodegradation potential. From naturally degrading sugarcane waste, bacteria were identified. 35 distinct bacterial species were discovered; these bacteria were then employed to determine each one’s potential for breaking down the lignin and cellulose found in sugarcane waste. After selecting a potential strain of bacteria, Congo red and iodine tests were created for the purpose of screening bacterial species, and they were then utilized to further the biodegradation of sugarcane waste. Thirteen of the thirty-five investigated bacterial species generated cellulase and ligninase enzymes, and Pseudomonas fluorescens was identified in the secondary screening as a suitable strain among these. Hence, this P. fluorescens was employed in the degradation of sugarcane waste. When this lingo-cellulolytic bacterium was introduced to sugarcane waste, the rate of degradation of the waste was enhanced. Significant reduction in lignin and cellulose contents were observed in sugarcane trash inoculated with P. fluorescens compared to other experiments. P. fluorescens lowered the C:N ratio in soil-mixed sugarcane waste from 70:1 to 10:1. The macronutrients of the compost taken from experimental trays seeded with P. fluorescens showed a substantial increase as well. It is evident from these results that the P. fluorescens, lingo-cellulolytic bacteria may be used for the degradation of sugarcane trash. Hence, we conclude that P. fluorescens can be recommended for the degradation of sugarcane trash which would result in the production of good quality compost containing higher amounts of total nitrogen, total potassium and total phosphorus contents.
