RT-Invest waste processing complexes (part of Rostec State Corporation) successfully conducted an experiment on growing flowers and vegetables in technogrunt obtained as a result of composting organic waste. In total, during the entire operation of the company's 4 complexes, about 550 thousand tons of technogrunt were produced.
The experiment was carried out on two complexes of the RT-Invest company. Lawn grass was planted in the resulting technical soil at KPO "North". For the purity of the experiment and for comparison, not only technical soil was used, but also specially designed for growing plants. The first sprouts appeared in the processed soil on the 7th day, and in ordinary soil on the 5th day of the experiment. As a result, the height of the lawn in the technogrunt was 20 cm, and in the usual-28 cm. After the experiment, the compost produced at KPO was sent to the laboratory for research. The results confirmed that it meets all environmental standards and specifications. But at the KPO "YUG" in the Kolomna city district, they decided to use a technogrunt to grow flowers in flower beds on the territory of the complex. Dahlias and petunias were planted. A surprise was the shoots of zucchini and tomatoes that appeared in the flower beds, the seeds of which apparently got there by accident.
At the moment, RT-Invest complexes use two technologies for processing organic waste by composting. The first is burt composting in hangars with stirring. Organic waste is placed in special burts for a period of 14 days. The second method is composting technology in climatic chambers. The pre-screened organic matter enters concrete structures 45 m long, similar to baths and covered with a membrane. This material protects the compost from precipitation and prevents the smell of organic waste from entering the environment. In the process of composting, special sensors are used that automatically monitor the parameters of the chamber, such as temperature and oxygen content. The finished technical soil is safe for the environment and is used by the company for its needs, for example, for pouring layers at the waste disposal site and when filling roads. And now for landscaping - landscaping of the territory of the complexes.
