Replacement of biodegradable packages in Amirkabir University

Have you ever thought how your role in environmental protection? Think about how much food packaging you throw out every day?!
Plastics play an important role in almost every aspect of our lives. The largest amount of plastics is found in containers and packaging that we use them just for once, in the meantime polystyrene foam packaging is a proven hazard to the environment in several ways.
Plastic products persist in the environment long after use, creating one such hazard. The widespread use of plastic within households make congestion a larger problem for landfills everywhere. one of the principles of waste management is reducing the production of waste at source. Waste management refers in part to diverting post-consumer waste from landfills, but it also refers to practices that prevent or minimize the use of certain materials in the first place. Several biodegradable alternatives have been created to reduce and eventually replace plastic waste. Biodegradable packaging plays an important role in the packaging industry due to the ever increasing consumer awareness and importance of using eco-friendly, biodegradable packaging materials instead of conventional non-biodegradable ones.
AUT office of sustainability with Amirkabir University Authorities cooperation in order to solve this problem decided to remove the polystyrene packaging from the waste stream generated in Amirkabir University’s dining room. For this purpose, sustainable waste management committee want to implement alternative plan of the containers for one month in dining room to be established in the event of acceptance by students.

Signs inserted in plastic containers

Have you ever wondered what these numbers are engraved on the bottom of plastic containers? If you are careful, letters or numbers, and sometimes both, are usually written in the middle of the recycling logo. If you have not seen it, do not worry, unfortunately, every moment you want, there is so much plastic container around you that you just have to reach out to pick one up.
But the story of these numbers: plastics are divided into 7 groups according to their type. With this knowledge, recyclable plastics, hazardous, low-risk, etc. will be identifiable.

Number 1: PETE or PET, which are the same bottles of mineral water that are relatively safe, but because of its porosity, bacteria can penetrate into the bottle, so I’m sorry to say that it is better not to reuse them. Leave them in the dry waste.

Number 2: HDPE or dense polyethylene. Plastic is safe. It is a dull color. Dishwashing liquid and other detergents are such plastics and are suitable for recycling dishes.

Number 3: PVC, which usually pipes are made of, as well as plastic raw materials that stick to food containers and liquid oil bottles. This type of plastic should never come close to heat when cooking because heat releases chemicals into the PVC and penetrates into the cooking food, causing hormonal disturbances, so use as much as you can. Avoid dishes with this material. Never put the material with the growing plastic in the microwave. In fact, these PVCs are bad and are not easily recycled.

Number 4: LDPE or low-density polyethylene. The same nylon shopping bags. These bags are safe but unfortunately usually non-recyclable.

Number 5: PP or polypropylene. Yogurt dishes and similar dishes that have wide openings. Also straw drinks. They are safe and easily recycled.

Number 6: PS or polystyrene. The same disposable tableware. These containers contain potentially toxic substances, especially when heated. Do not use these containers as much as possible. Most of the time they were non-recyclable.

Number 7: The same famous option of other cases. From computer cases and iPods to food containers. Using this plastic, especially for food, is always your last resort, and this number 7 is usually non-recyclable.

I do not know if you noticed or not, but the worst ones were the nylon bags and disposable containers that are both toxic and difficult to recycle. But unfortunately, these worst ones are also among the most.
