GreenSavings (PoupVerde)

Development of a dApp for the collection of waste used cooking oil, in exchange ADA, which will be used for the production of biodiesel.

The team has transversal skills in the areas of socio-environmental entrepreneurship, education, blockchain and software development.

.

Problem description:

Every day liters of used cooking oil waste are incorrectly disposed of by the population around the world. These residues represent a serious risk to nature, as they pollute and contaminate the environment.

Oil producers are required to offer the population ways of efficiently disposing of these wastes and also reusing them to protect the environment. Soap and biodiesel are examples of products that can be made from these residues, further reducing extractive damage and GHG (greenhouse gas) emissions.

There is a great educational challenge, especially in developing countries, such as Brazil, which do not have in their educational curricula the formation of sustainable principles and protection of the environment in new generations, without a doubt the best way to promote the reduction of human impact in nature.

Solution Description:

Development of a dApp for the collection of waste used cooking oil that will be used as an input in the production of soap and biodiesel. In return, waste used cooking oil donors will receive credits in ADA cryptocurrency - green savings.

This dApp, the main gear of a socio-environmental education project developed by IDESC - Instituto Humanizar, based in Brazil, will be a platform for registration and access control of participants and partners, accounting for oil delivery and respective reward credit (green savings ), and a means of communication and interactive environmental education between the project and the participants.

The objectives of this solution are: to combine the process of environmental awareness with incentives for participation based on obtaining rewards in cryptocurrencies; promote knowledge of blockchain technology; promote financial education through the concepts of planning, savings and investment; and, to foster the local economy in cryptocurrencies, through IDESC partnerships with merchants to accept ADA at their establishments.

The dApp will be developed for the Android mobile platform, using the Flutter framework, which will allow it to be more easily ported to the iOS platform, in later stages of software evolution.

As a way of guaranteeing the viability of the solution, in addition to IDESC having a biodiesel plant, it will formulate contracts with supporting partners to anticipate the financial contribution to the project and the corresponding counterpart in the supply of biodiesel. Part of these funds will be used to purchase ADA cryptocurrencies that will be paid as a reward to oil waste donors through smart contracts.

Extra benefits of this proposal:

With the need to introduce this Dapp to a new generation of children and teenagers, we will have the opportunity to explain Cardano's blockchain and how it presents itself as a green alternative to bitcoin. We will teach you what smart contracts are, how they interact with a wallet, create and keep keys.

Not only the question of technology, we will have the opportunity to alleviate a significant deficiency in financial education by touching on the subject; what is money. This process will be done using presentation material and organized according to the steps for implementing the solution in the school.

Detailed Plan:

These are the modules and respective functionalities of the proposed decentralized application:

Module - Admin Agent:

1. Register of oil waste donors identified by the Individual Taxpayer Registry (CPF) and Cardano's wallet;
2. Credit table registration (weight and reward value);
3. Register of oil waste receivers identified by the Individual Taxpayer Registry (CPF) and Cardano's wallet;
4. Authorization of recipient agents in the smart contract to release credits for donor agents;
5. Panel showing the flow of deposits and withdrawals (payment of credit to donors and recipients) in the smart contract;

Module - Donor Agent:

1. Waste donation credits display panel;

Module - Receiving Agent:

1. Panel for receiving oil waste donation (allowing to inform weight and identification of the donor (reading QRCode from the donor's wallet) and signing the smart contract to release the green credit payment);
2. Panel for viewing the credits received for working receiving waste;

Module - General:

1. Environmental education and communication panel;
2. Panel showing the amount of oil removed from the environment, and the estimated reduction in the GHG (greenhouse gas) emissions index.

IDESC (Stakeholder)

IDESC (Institute for Sustainable Development of Communities - "Instituto Humanizar"), is a non-profit public interest civil society organization, established in 2008, with the possibility of acting at national and international level, composed of people with multidisciplinary action and identified with social and environmental causes and actions, with a special focus on social entrepreneurship projects, which combine educational processes and technological innovation, as a way of transforming society.

Our main interest today lies in the use, dissemination and promotion of new technologies capable of enabling the generation of income and encouraging social entrepreneurship, education and environmental preservation. In addition to working on environmental protection and consumer rights at the legal level, through public civil actions.

Long term plan:

IDESC, as the solution manager, will expand the adoption of this dApp throughout Brazil. To this end, it will establish partnerships with other institutions in the third sector, soap and biodiesel production plants, and merchants to accept ADA as a form of payment in their businesses.

Other potential features to be implemented in the future:

• Integration of the dApp on the iOS platform;
• Inclusion of donation of other waste and recyclable materials, in partnership with cooperatives of waste collectors;
• Creation of the project's native token (currency);
• Creation of NFT tokens for waste donation goals achieved by the user;
• Self-service totem for receiving oil waste;
• Integration with other educational and professional training projects;
• Central for attracting investors and sponsors.

Risk:

• There is no integration with the Yoroi Mobile wallet;
• Delay of delivery of the Goguen Phase by Cardano;
• Insufficient documentation of the Plutus language;
• IDESC does not enter into partnerships with supporters to anticipate financial contributions to the project, which would be used to pay the rewards.
