Typically, 6 bottles may be sterilised at a time, and the procedure can take as little as 6 minutes. Once your baby's bottles and feeding equipment have been sanitized, you can store them inside for up to 24 hours. Some may even sterilise and dry infant bottles at the same time. All plastics release some amount of toxic substances when they break down. When you recycle plastic bottles, these chemicals are released into the environment through either landfill sites or incinerators. Recycling is better for the environment than throwing plastic bottles in the trash, but it's not perfect. If you don't recycle plastic bottles, they will end up in landfills or incinerators and cause environmental problems of their own. The type of resin used to make plastic bottles affects how easily those bottles break down when exposed to heat or light. Polyethylene terephthalate (PET) bottles and containers made from polyvinyl chloride (PVC) tend to break down more quickly than those made from other materials. This is because PET and PVC contain carbon-carbon bonds that are more likely to break if exposed to heat or energy. These bottles should not be put in the dishwasher or subjected to high temperatures while they are still wet. The material might come off in your hands if you wash them with hot water and soap. There are several options for recycling plastic bottles. Most large grocery stores and food manufacturers collect recycled plastic beverage packaging.
