The world's first 'infinite' plastic - BBC Future
The process is fairly simple – take a plastic drinks bottle. You put it out with your recycling for collection. It is taken, along with all the other waste, to a sorting facility. There, the...

Plasticizer removal process and system Abstract The contamination of machine components by a plasticizer such as dioctyl phthalate is controlled by placing a plasticizer...
How Yemen’s conflict destroyed its waste management system
Of Yemen’s 21 officially designated dumps – the total number varies depending on how they are classified – only six were operated with any degree of control in 2009. Unless properly designed and managed, such sites can generate water and air pollution and carry the threat of disease.
Development of hybrid processes for the removal of volatile
For the hybrid process (1), the removal of xylenes, TCE, and cis-DCE was enhanced, resulted from the contribution of both physical adsorption and biological immobilization removal. The hybrid process (2) was also superior for the removal of DEHP and required a shorter time (2 days) for the bioremoval. For the process (3), the biochar promoted

3 during the mixing process. However, the compatibility between the types of plasticizers could effect the cross linking reaction in rubber matrix [9]. Thus, different plasticizer influence the speed of insertion filler into rubber matrix and the homogeneity between reinforcing and nonreinforcing filler [10]. Thus, it could yield the different -
- Can a synergistic system be used to remove plastic additives from water?
- The removal rate was related to the concentration of rhamnolipids in the synergistic system (Tian et al., 2023). Therefore, the establishment of a rationally designed and effective synergistic system for the flocculation/coagulation process can provide a feasible direction for the removal of plastic additives from water. 4.1.2. Adsorption
- Can abiotic methods be used to remove plastic additives?
- The study of these strategies could (i) provide feasible, cost-effective abiotic method for the removal of plastic additives, (ii) further enrich the current knowledge on plastic additive bioremediation, and (iii) present application and future development of plants, invertebrates and machine learning in plastic additive remediation. 1.
- Why are plasticizers ubiquitous in the environment?
- Plasticizers are ubiquitous in the environment due to their widespread use as additives of plastics. Phthalic acid esters (PAEs) as plasticizers have received increasing attention.
- Do plastic additives migrate and Leach?
- In general, plastic additives have the potential to migrate and leach during the use and recycling of plastic products, which can pose a serious threat to humans and ecosystems (Fig. 3). Therefore, studies on the migration and leaching of plastic additives can help assess the exposure and hazards of plastic additives. Fig. 3.
- Can bioremediation help reduce plastic pollution?
- Bioremediation using microorganisms/enzymes is a highly promising strategy. In addition, some plants and invertebrates may also have the potential to remediate the pollution caused by plastic additives.
- What are plasticizers & Paes?
- Plasticizers are additives that increase the ductility and flexibility of plastics and are usually classified into two main categories: phthalates and non-phthalates. PAEs are an important class of organic compounds formed by esterification of phthalic anhydride and alcohols under acidic conditions.
