Help me Build a small plastic recycling plant in my backyard

I'm from Goa an i am very much inspired by this community. Precious Plastic: https://preciousplastic.com/en/community.html

I have a lots of space to start a small plastic recycling plant in my backyard and want to build machines that are listed here https://preciousplastic.com/en/machines.html

My plans are to first build these machines and test how they work and then try out different things.

I also have plans to give some of these recycling machines to nearby schools to create awareness on recycling plastic and show them how recycled materials that can be used in schools like plastic cupboard, tables, chairs etc

I found 3 machines listed on their site.

Seller nearest to my location https://bazar.preciousplastic.com/en/garry2017

3. Injection Machine

Help me set up these machine and build a recycling plant. and do support the precious plastic community.
