DOOST INTERNATIONAL (DI) is a German start-up/company and consortium
working for blue-green sustainable business in SMEs, governments, countries and cities in regional, local, national, multinational, international and global level.

DI is Thinking Globally and Acting Regionally!

Most of the governments, countries and cities around the global world encounter many today’s challenges and tomorrow shocks. Based on the 5th wave/tomorrow age theory (invented by Prof. Dr. Hamid Doost Mohammadian, 2010, revised, 2017-19), some of these key issues include inefficiency of livability, quality of life, human health and welfare, energy, natural resources, asset distribution, administration, air and light pollution, waste management, climate change, and wildlife contamination.

The DI consortium is a start-up established to assist local and global SMEs, governments, municipalities and private sectors to solve current urban challenges by building and developing human-centric sustainable area around the global world and new model of SMEs entitled ‘’Hybrid SMEs’’ which is a new method which can enable SMEs to better management of resources and flexibility to respond to the business conditions for tomorrow age theory readiness. Hybrid SMEs founded on technology, HR competencies, sustainable strategies like CSR or smartness could develop sustainability and create livable urban areas with high quality of life. (by balancing between technologies, humanities, natural resources, CSR & business economy)

DI is organized as a consortium with associated business consultants, sustainable universities, modern institutions, hybrid SMEs and private production companies and provide strategies that build the infrastructure, foundation and structure of sustainable growth models for global governments, countries and cities.

The DI consortium consists of experts, SMEs and managers with long local and global experience based on 7PS Model (invented by Prof. Dr. Hamid Doost Mohammadian, 2019): social, environmental, technical, political, cultural and economics.

Prior to international successful experiences, DI has developed some working models with a number of efficient tools for sustainable business, sustainable energy plans and production.

The 7PS model covers sustainable business, economy and energy from sun, wind, thermal, waste, wastewater and different ways to successfully combine these energy forms.

The new trends in “Blue-Green Sustainability” encompass the seventeen sustainable development goals and the 7PS model, which is focused on the seven pillars of sustainability as below figure:

Our Visions:

Blue-Green Sustainable Energy

As technology is evolving at a rapid rate, DI is creating new more efficient forms of sustainable renewable energy. DI is looking at the best practices to save energy by not only finding and working with SMEs that are building new processes and solutions, but also working with our partners to help support their development.





Infrastructure is the foundation for any sustainable business. With a good base a business can ready itself for tomorrow development and new technological advancements. With the increase of interest in smartness and smart SMEs we are entering a new era for people, livability and quality of life.




Cross Validation


DI has created a system where we are able to connect cities together and produce city sized Sandboxes. By learning from existing blue-green sustainable smart business we can come up with global solutions that can work with similar cities around the world. This will bring new levels of collaboration and will improve the rate of global development.



Business, Marketing and Technological Innovation


Business, marketing and technological innovation are the infrastructure and foundation of blue-green sustainable business. Without business, marketing and technological innovation, solutions to tomorrow shocks and urban challenges cannot be solved and so the DI strives to select innovative technologies that can aid in blue-green sustainable smart comprehensive planning.



Blue-Green Sustainable Mobility



Whether it’s commuting to work, popping to the shops or seeing friends, connected transportation systems offering flexibility, effectiveness and efficiency are key to the happiness of quality of livability and citizens’ lives. DI is looking for the most efficient and blue-green sustainable alternatives such as electric bikes and buses to reduce CO2 emissions and noise pollution, as well as improve quality of livability and citizens’ lives (high sustainability).


Water, Wastewater & Waste


Many developing countries struggle with access to clean water, wastewater and waste which should not be the case as today’s challenges in the 21st Century and the 5th wave theory readiness for facing tomorrow shocks. DI strives to find the sustainable solutions and practices to make clean, running water a commonplace globally for the betterment of people’s lives.



Blue-Green Sustainable Economy


DI’s goal lines up with the UN to help local and global SMEs, governments, municipalities and private sectors to utilize projects and build systems to encourage circular economies. The goal is to use resources more efficiently by saving and using them over and over as well as encourage a society to think about reuse and recycling (waste as energy resource).




Health, Labor and Social Welfare Security


Home automation systems are set to be an integral part of day to day life, controlling lights, heating, energy usage, appliance control, access control and social welfare security. There are currently few worldwide accepted standards, so here at DI our aim is to make a more cohesive set of standards that will be more widely installed into people lives with CSR approaches.
