Projeto sustentável para uma pequena propriedade rural no município de Caxias do Sul/RS

Abstract

This work presents a sustainable project for a small rural property located in Caxias do Sul/RS. The main problems encountered are related to the environment, they relate to four important factors: high water consumption, waste generation, effluent generation from the fruit washing process, and high electricity consumption, especially in the harvest period. With the need to optimize spending, seeking clean and sustainable technologies in order to make agricultural farms more sustainable, 4 systems have been proposed. This project presents the design of a rainwater harvesting system for fruit washing, agricultural machinery washing, sidewalks and irrigation. Its sizing resulted in a 250 L roof washing water disposal reservoir, and a 20,000 L capacity storage reservoir. The sizing of the water reuse system for fruit processing resulted in 3 reservoirs, the first for wastewater collection (1000 L), the second for the slow filter (5000 L), and one for storage (1000 L). In addition, the project features the design of a photovoltaic power generation system that aims to reduce the consumption of non-renewable energy sources. The photovoltaic system comprises 70 units with 320 W photovoltaic panel and 1 22.5 kW capacity inverter. Finally, the Leira-sized organic waste composting system with a capacity of 84.2 kg / day of waste, generating a compost that can be used as fertilizer on the property. The feasibility analysis of this project contemplated 3 distinct scenarios, presenting itself as viable. Among several benefits achieved with this project we can highlight the minimization of environmental impacts and a gain in the image of the property.(sic)
