. In the article, it is based on the fact that the need to use limited resources more rationally and effectively is the main issue of the economy and the guarantee of the stabilization process of the economy. Unfair behavior towards the environment in the provision of unlimited needs can endanger the life of future generations. Therefore, today the role of "green economy" is incomparable. The author's opinion and suggestions in this regard are recorded in the article.

The process of obtaining soda on the basis of Mirabilit is a technology without waste, as a result of the conversion, ammonium sulfate is formed. Ammonium sulphate is an excellent fertilizer for folk remedies. This mineral fertilizer, which holds nitrogen and sulfur in itself, dissolves well in water and prolongs well from the roots of the usimites and does not wash away as a result of rain.

This paper is devoted to modeling of geophysical signals based on the parabolic spline function of local interpolation and processing of geophysical signals based on spectral analysis of signals. It is shown that the use of spline functions for constructing a mathematical model of digital processing and recovery of various geophysical signals is currently relevant for solving practical problems. The first experimental data of geophysical signals were taken as an example, and a parabolic local interpolation cubic spline model was constructed based on these data. Also presented is the process of interpolating the geophysical signal using the built-in local interpolation cubic spline model.
