Recycling System using IOTA

Hello everyone, In the last article I talked about the implementation of a database system using Tangle and IPFS. Today I am going to present a use case for my database. I will create a recycling system. The recycling industry faces a serious challenge, The quantities of recycled materials is inconsistent and hard to estimate. So we will use Blockchain to solve this problem.

Application Scenario

Consumer#A wants to recycle his laptop, smart-phone or watch… whatever. Consumer#A scans his consumed product using NFC on his smartphone and go to our smart Trash. Our smart trash scan the NFC tag and send Consumer#A some MIOTA as rewards for recycling.

How It works

Assume a laptop factory interested in recycling his laptop after consumption by the user.

1- Factory well send all his laptop data and IDs to our system to be saved on our system. (IDs will be the key to access each laptop)

2- All laptops will be saved with states like:’ not found, found by Consumer #a, Found at trash#B’

The database will look like this:

3- All laptops will have NFC tags to write the ID.

4-Now consumer will scan the laptop he wants to recycle. Once you scan the laptop an API call will set the consumer as the owner of the recycled laptop.

5- Whenever the consumer puts his laptop to our trash he will earn tokens as rewards.

API implementation

First, I will start with the API design it will look like this:
