Logistics for recycling
High-quality reverse logistics are essential to close the loop of a product’s life cycle and help transition to a circular economy. Reverse Logistics are the operations related to the process of moving goods
from their typical final destination, for the purpose of capturing value or proper disposal.
This can include many things, such as the collection and transportation for returns,
repairs, refurbishment, recycling, reuse or re-manufacturing, etc. Issues such as data security, privacy and corporate secrets are serious concerns for businesses who decide to recycle their unwanted IT and computer equipment.
Two Case Studies
In the social and life sciences, a case study is a research method involving an up-close, in-depth, and detailed examination of a particular case. For example, a case study in medicine may examine a specific patient a doctor treated, and a case study in business might study a particular firm's strategy. Generally, a case can be nearly any unit of analysis, including individuals, organizations, events, or actions. In the two-case study it is tested several times and several methods are used. Two case studies are done in order to get better and more powerful singe-case studies. The more case studies, the better the result. One-case Studies can also bring good results, however, it is not as exact as two case studies. In two case studies you use different date collection methods. You can also have a more than two case studies. The results will get more specific.

For our calculation we have chosen a microwave oven with 1000 watt power. The picture below shows the energy consumption of a microwave oven that is used for 6 minutes per day.
This is the formula to calculate the value: E(kWh/day) = P(W) × t(h/day) / 1000(W/kW)

Goal: The Goal is to share the clothes with each other to reduce the embodied energy and the resources needed to produce new clothes.
Reason: Nowadays people buy or order too many clothes. This is bad for our environment as we use many resources and emit a lot of Co2 during transportation. With our idea we want to reduce this sort of consumption.
Saved resources: Let us imagine a cotton shirt that weighs around 200g. To get the cotton for this one shirt, about half a kilo of raw cotton is needed. To grow this amount of cotton, an average of about 7m² of land is needed. Seven square meters of land are therefore needed to produce the raw material for a normal cotton shirt alone. To get to the finished product, however, several steps are still missing, such as sewing the fabrics and transport from the country of production to the shops. All these steps consume different amounts of energy and so, in total, almost 11 kilograms of CO2 are emitted in the life of a cotton shirt. With our idea you could save all the energy and resources!
Our idea: Our idea is to use an application developed by us to give the clothes of the population to other people for free or for little money. You are probably wondering how this works? You register in the app and then you can chat with others about costs and how or where the clothes are handed out.
The whole project has many advantages. Some of them can sell their old clothes for free or even for a small profit and poorer people can also get wearable clothes. But the most important thing is that our environment is protected.
Now it's your turn. The development of the app is currently in the final phase. You can help us by promoting the app for example via social media etc. Let's save our environment for a better future for all of us.
