Biodigester at The Laboratory of Animal Biology

 Dear  collaborators 

The biodigesters have multiple uses for sanitation.

In the photos attached to the report can be seen from all the faces of biodigesters construction.

This biodigester was installed at the State Center for Animal Health - State of Rio de Janeiro - Inside the Zoo Niterói, RJ.

This is an installation of animal research with 50 administrative staff. Teachers doctors, technicians and other employees.

The Laboratory of Animal Biology, Botanical Garden, located in Niterói since 1939, has structure and specialized technical staff, enabling him to develop studies and research in Animal Health and Nutrition.

Has areas of Bacteriology, Virology, Biotechnology, Pathology, Clinical Pathology, Animal Nutrition and Instrumental Analysis, also performing analyzes of animal products and water to serve the community and contribute with actions to preserve the environment.

Shares of Research in Animal Health and Diagnostic generate fundamental information to support the Superintendency of Sanitary Defense of the State Secretariat for Agriculture, Livestock, Fisheries and Food Supply.

The biodigester seen in the photo will treat domestic wastewater from the administrative part. In another step others will be installed for the treatment of effluents from the laboratories.

This platform philanthropy is very important to the work done.

Many thanks and best regards!

Dairy cows biodigester in Valenca, RJ

A pre treatment place

Dear partners,

Thanks to this wonderful philanthropic platform that is the Global Giving, the this project take digesters for rural community, generate energy and clean up the environment.

The IDDEIA develops projects in almost all areas of the environment. We manage the Waste Units, provide maintenance of water treatment plants, build sewage treatment systems, Legal Reserves, license projects in general, etc..

Environmental planning, trash, water, drainage and sewage from cities, are among the services we provide.

Below you can see photos of the beginning of a project sanitation and energy generation on a farm that has 25 dairy cows.

We can see in the photo the construction of pre-treatment of the waste generated by this corral.

This project will treat 300kg of manure per day and generates nearly the equivalent of fifty bottles of gas per month.

We hope to build many of these yet and we are very grateful to you for providing the realization of this project.

Biodigestor by organic waste

Rio Preto Trash Unit
Rio Preto Trash Unit

Dear partners,

The IDDEIA Institute in partership with Rio Preto county, MG, Brazil, are developing together projects to increase donors in Global Giving plataform. This projects will be developed in Rio Preto couty instaling biodigesters.

We are instaling one biodigester for city organic waste. This waste are previousilly separete from recicle one in a City Trash Unit County.

Iddeia manage this Unit and teach enviromental education on county schools. This action ins very important to suport eficient separate fases in the Trash Unit;

This project forecast use orgnnic and domestic trash with animals manure. We already count on with the Federal Rural University from Rio de Janeiro and PESAGRO, the Rio de Janeiro Rural Research Company.

Bests regards,

Biodigesters for sewage in rural needy pour families.

Biodigester in the basement
Biodigester in the basement

Dear collaborators,

Our project due to the support of this Great Entity proceeds offering us help to continue our effort to improve our environment.

Beyond our already mentioned applications of the biodigester in rural communities, we recently improved it to be used in private residences, resorts and entire communities.

Through annexed photos you will be able to see an antique pit, used by five needy poor families in the basement of an old home, now replaced by a biodigester.

On another photo we can see an old biodigester totally  buried underground. We can observe the pre-existing and the new  existing system.

Before entering our biodigester, the sewage of ten houses go through a double process of grating and sifting to eliminate non-biodegradable materials. This facilitates the anaerobic bacterias to perform its work.

Once again the biodigester comproves itself as an efficient utility that utilizes the best and proven techniques to better and save our environment.

It is a very low cost sewage treatment that permits the best way for society to turn its organic waste into a clean and reusable utility.

This process will also generate energy through the production of methane gas depending on

the size and the number of people using it.

The importance of the help offered us by your entity and collaborators is highly appreciated.

The environmental, social, economic and health benefits offered to the communities by the biodigesters are proven.

Sincerely and gratefully,

Others biodigesters skills

Recently, with the advance of our project we observed its relevance protecting and retaining slopes taking in consideration that it directs the flow to the reactor, depositing them into an adequate place to perform its job.

The biodigester has technical qualities that permits them to be installed in places of difficult access. Normally in locations where farmers with low resources live with landslides caused by castratophies.

The biodigester brings sanitation, thermal energy, geological security, safe food and better life quality to the small agricultor. Most importantly climatic safety for our planet.

This photo, for example demonstrates the damage caused by pig sty cleaning with abundant quantity of water causing damage to slopes.

Using our biodigestor with our new Project we now changed its entry and its exit in order that all pig sty be treated and also producing gas for domestic use.

As this photo demonstrates, they can improve the life quality of the small farmer and our environment.
