What country is your selected Place located in?


Describe your relationship to the place you’ve selected.

Assam is the native place of ENVIRON where most of the activities are going on. 

Assam is the place where organic farming is still practicing in different Villages as the part of traditional farming methodology.  Earlier Tea garden of Assam was also organically farmed which is now obsolete due to the lack of sufficient production of Organic Manure and 'Bio-pest Repellent'. On the other hand, Assam is having enough potentiality to utilize abundantly available herbs, shrubs, leaf litters, water hyacinth and other plant and animal waste for producing 'Organic Manure' and 'Bio-pest Repellent' to practice 'Organic Farming' through the invented "Waste Assimilator".

ENVIRON has already tested the ‘Innovation’ through 14 different pilot projects covering nearly 100000 populations of Assam, Arunachal Pradesh and in West Bengal three states of India. Accordingly, qualified team members of ENVIRON are now well experienced for promoting the “Waste Assimilator” and organic farming. 

Describe the People and Place: Provide information that would be helpful for an outsider who has never been there and may have no context about this Place to better understand the area.

Assam is a northeastern state of India. The climate and the people way of life is quite different from the rest of India. Assam and adjoining regions have evidences of human settlement from the beginning of the Stone Age. Assam has tropical monsoon climate with summer max. at 95–100 °F or 35–38 °C and winter min. at 43–46 °F or 6–8 °C. Spring (March–April) and autumn (September–October) are usually pleasant with moderate rainfall and temperature.  

Assam's economy is fundamentally based on agriculture. Over 70 percent of the state's population relies on agriculture as farmers, as agricultural laborers, or both for their livelihood. Assam produces both food and cash crops. The principal food crops produced in the state are rice (paddy), maize (corn), pulses, potato, wheat, etc., while the principal cash crops are tea, jute, oilseeds, sugarcane, cotton, and tobacco. Tea is the most important cash crop in Assam and the state is well known world-wide for its Tea.

The prime geographical characters that form the topographical features of Assam are the Barak Valley and the River of Brahmaputra. From north-eastern corners to west and further towards south, the Brahmaputra River spread its rich alluvial plains across the length and breadth of Assam.

Assamese is the official language of the state. Additional official languages include Bengali and Bodo languages.

Assamese Culture is traditionally a hybrid one developed due to assimilation of ethno-cultural groups of Austric, Dravidian, Tibeto-Burman and Tai origin in the past. There are several important indigenous traditional festivals in Assam. Bihu is the most celebrated festival among all.

However, the food in Assam is very tasty, unique and very similar to the neighboring north-eastern states. The households used commonly Mustard oil in every dish for its availability in a large range in the state. Assam food habits are mostly non-vegetarian, rice with fish curry is the main food item to the Assamese. They also used vegetables, bamboo shoots, jackfruits, olives and bananas during their taking food.

Assam shares about 2.4 % of the country’s total geographical area and provides shelter to 2.6 % population of the country. Assam has heterogeneous population with socio-cultural & ethnic diversity. As per the 2011 census, the total population of Assam was 31,169,272 out of which 159.39 lakh are male and 152.66 lakh are female. In 2011, the literacy rate in the state was 73.18%. The male literacy rate was 78.81% and the female literacy rate was 67.27%. Out of the total population, 86 percent population live in rural areas & 14 percent population live in urban areas of the State.

What is the approximate size of your Place, in square kilometers? (New question, not required)


What is the estimated population (current 2020) in your Place?


Challenges: Describe the current (2020) and the future (2050) challenges that your food system faces.

According to the UN, the planet’s population is set to exceed 9 billion in the next 35 years. On the other hand according to the World Food Program, at the present scenario one in every nine people is not getting enough to eat. Accordingly some experts says that the problem isn’t that we won’t have enough food, it’s that the current agricultural system which is failing us to provide adequate nutrients. At the present scenario about 800 million people are hungry and another two billion people suffer from life-threatening disease related to under-nutrition and contamination from chemical pesticides. The World Health Organization has defined food security as “when all people at all times have access to sufficient, safe, nutritious food to maintain a healthy and active life.” Only organic farming can provide us a viable option to feeding the planet with adequate nutrients. Foods from organic farms are loaded with nutrients such as vitamins, enzymes, minerals and other micro-nutrients compared to those from conventional farms. Whereas, small scale organic farming is the only logical solution to the world’s food needs, according to a report from a United Nations organization. Organic farming uses ecologically based pest controls, bio-pesticides or bio-pest repellent and biological fertilizers derived largely from animal and plant wastes. However, due to the lack of adequate amount of organic manure and bio-pest repellent it is practically not so easy to practice organic farming to replace the present conventional inorganic farming. As of 2019, approximately 70,000,000 hectares (170,000,000 acres) worldwide were farmed organically, representing approximately 1.4 percent of total world farmland. Therefore, there is an urgent need to innovate a technology for producing organic manure cum bio-pesticide by utilizing daily generated organic waste (usually available raw material) for practicing organic farming in every household.

On the other hand, according to the latest socioeconomic census of India, 73% of the population lives in the villages. Out of this, less than 5% people earn enough to pay taxes, only 2.5% own a 4-wheeler vehicle and less than 10% have salaried jobs. A huge pool of our population lives under poverty without minimum basic amenities. 35.7% of these populations are still illiterate and only 3.5% students continue their education up to the graduation level. The scenario is more pathetic in the North eastern states including Assam.

Address the Challenges: Describe how your Vision will address the challenges described in the previous question.

To fulfill the requirement a “Waste Assimilator” is invented (Patent C.B.R. No. 13952) to produce ‘bio-pest repellent’ and ‘organic manure’ in the form of ‘Microbial-wash’, ‘Vermi-wash’ and finally ‘Vermicompost’ by utilizing all type of daily generated organic solid waste including kitchen waste, fruit & vegetable waste, unwanted herbs and shrubs, weeds, leaf litters, agricultural waste, meat and fish waste, aquatic plants waste, cattle dung etc. The “Waste Assimilator” introduces an improved technology for composting of daily generated biodegradable solid waste through microbial aerobic digestion and assimilation by earthworm. It is simple in structure and operation offering continuous collection system of both ‘organic manure’ and ‘bio-pest repellent’ in the form of ‘microbial wash’, ‘vermiwash’ and finally ‘vermicompost’ to practice small and large scale organic farming.

Invention of “Waste Assimilator” is now inspiring organic farming and up to 80% domestic solid waste problem can be solved and a significant reduction of the roadside dumps can be achieved. The invention of domestic “Waste Assimilator” is now generating the concept of household solid waste management and small scale organic farming. On the other hand, bigger size community “Waste Assimilator” can manage the community or market generated biodegradable solid waste to practice large scale organic farming. 

Due to the invention of “Waste Assimilator”, it is becoming now possible to produce ‘Organic Manure’ and ‘Bio-pest Repellent’ from the daily generated biodegradable solid waste to practice household as well as large scale ‘Organic Farming’. The invention is now generating the concept of practicing organic farming in every rural household which will definitely enhance individual food safety and economic growth to build an Organically Green, Healthy, economically sound & Sanitized World. 

Due to the invention of “Waste Assimilator”, people will get the benefits by following two different ways:

  1. Production of ‘Organic Manure’ and ‘Bio-pest Repellent’ for utilizing in own cultivated land and also for sale.
  2. Production of ‘Organic Crops’ and ‘Organic Green Tea’ for own consumption and for sale.

This would, in turn, ensure sustainability which does not require any additional financial support.

High Level Vision: With these challenges addressed, now provide a high level description of how the Place and the lives of its People will be different than they are now.

Renewal of every renewable natural resource towards a healthy environment and mitigation of poverty and hunger:

To combat this situation, every stake holder of the society will be motivated towards renewal of every renewable natural resources and their scientific utilization. A revolutionary step in this regard has become a need of the hour.

The present scenario of injudicious over exploitation of natural resources creates threat to the survival of our planet. Therefore to generate opportunity and develop proper guideline, scientific study, analysis and propagating strategy of every renewable natural resource is becoming inevitable.

By considering the fact, ENVIRON is planning to establish an “Institute of Renewable Resources” for the renewal of every renewable natural resources towards a healthy environment and mitigation of poverty and hungry.

The Institute will address scientific utilization of every ‘Land Resources’ through plantation of important trees, highlighting the economic benefits of different plants for encouraging maximum plantation, restoration of forest and wildlife habitat, organic farming by utilizing organic waste, agricultural development, livestock development, poultry development, fishery development etc. as a part of renewal of renewable natural resources and environment management for mitigation of Poverty and Hunger. 

Full Vision: How do you describe your Vision for a regenerative and nourishing food future for your Place and People for 2050?

The Widespread use of pesticides has become a serious environmental problem now a day. With promotion from different agencies, increasing competitiveness, decreasing land areas & production level has forced farmers to use pesticides. In these practices the safety norms are grossly violated resulting threat to the ecosystem and human life. Development of resistant variety along with new pests forced the farmers to try overdose as well as new forms of pesticides. This result increased financial burden on the farmers leading to a form of vicious debt trap, even committing suicide in many parts of the country. In this backdrop a growing trend has emerged in various part of the world to seek alternative of chemical pesticides.

To fulfill the requirement, a “Waste Assimilator” is invented (Patent C.B.R. No. 13952) to produce ‘bio-pest repellent’ and ‘organic manure’ in the form of ‘Microbial-wash’, ‘Vermi-wash’ and finally ‘Vermicompost’ by utilizing all type of daily generated biodegradable solid waste including Kitchen waste, Fruit and Vegetable peels, Meat & Fish waste, Agricultural waste, Garden waste, Forest waste, Water hyacinth etc. Through the use of “Waste Assimilator”, up to 80% domestic solid waste problem can be solved and a significant reduction of the roadside dumps can be achieved, Kashyap et al. (2017). On the other hand, bigger size community “Waste Assimilator” can manage the community or market generated biodegradable solid waste which can inspire large scale organic farming in rural areas.

Advantages of ‘Waste Assimilator’:

This invention introduces an improved technology for composting of daily generated biodegradable solid waste through microbial aerobic digestion and assimilation by earthworm. It has an ‘aeration layer’ for faster microbial growth and rapid digestion of biodegradable solid waste. It is designed for household use with a very easy process of regular waste disposal above the composting bed without additional moistening system. As soil-eater earthworms cannot efficiently assimilate biodegradable solid waste, therefore, earthworm is collected from decayed banana plants (is a resistant variety of heat, generated from the pre-decomposed waste). Simple ‘plastic cover’ is enough over the assimilator. Fresh biodegradable waste consisting of water is enough to moisten the unit. It is simple in structure and operation and specially designed for the daily generated household biodegradable solid waste management offering continuous collection system of ‘microbial wash’, ‘vermiwash’ and finally ‘vermicompost’.

Daily generated biodegradable solid waste can directly be disposed inside the composting bed of the “Waste Assimilator”. The “Waste Assimilator” produces ‘microbial-wash’ from 1 to 2 days of use, ‘vermi-wash’ from 25 days till the assimilation process continues and finally ‘vermicompost’ after 120 days. The ‘microbial-wash’ and ‘vermi-wash’ can be used both as ‘organic manure’ and ‘bio-pest repellent’ where as ‘vermicompost’ is one of the best organic manure. Thus, people can practice ‘Organic farming’ and ‘Organic Tea Gardening’ out of their daily generated biodegradable solid waste. Accordingly even unutilized and unfertile land can be converted to usable and fertile land by utilizing the nutrients derived from the “Waste Assimilator”. Thus the invention of “Waste Assimilator” is now generating the concept of ‘Solid Waste Management and Organic Farming’ which is also opening a path for the basic economic growth to build an ‘organically green’, ‘economically sound’, ‘healthy’ & ‘sanitized society’. 

Nutritional component produced from the “Waste Assimilator”:

‘Microbial-wash’, ‘Vermi-wash’ and ‘Vermicompost’ contains:   Nitrogen, Phosphorus, Potash, Amino Acid, Enzymes, Organic Carbon, Calcium, Magnesium, Zinc, Iron along with Vitamins, different Hormones and many useful microbes.

Thus, the invention is now generating the concept of Solid Waste Management and Organic Farming

In this process our ultimate dream is to utilize all the unwanted biodegradable solid waste to produce both ‘Organic Manure’ and ‘Bio-pest repellent’ by the use of “Waste Assimilator” to promote ‘organic farming’ for initiating an organically green, healthy, sanitized and economically sound World.
