“…Por isso, faz-se necessário a melhor gestão possível, por meio da elaboração adequada de procedimentos e normatizações para o gerenciamento de tais resíduos. É importante que haja a participação de todos os colaboradores, por meio de ampla mobilização, e a elaboração de um Sistema Gerenciador Interno dos Resíduos Sólidos, que conterá a determinação dos procedimentos, os setores responsáveis, as metodologias de segregação na origem, as formas de acondicionamento e transporte, além de confecção de planilhas de controle de resíduos (NAIME, 2005 Nesse contexto, Saidelles et al (2012) orientam que para as empresas que não reaproveitam seus resíduos, o passo inicial é justamente o mapeamento de resíduos gerados no processo, uma vez que essa prática é o passo inicial para a introdução de um sistema de gestão ambiental. Os referidos autores sinalizam que a reutilização dos resíduos também possibilita a redução do impacto ambiental causado e gera uma economia decorrente da redução dos custos de produção, uma vez que os resíduos retornam ao processo produtivo sob a forma de matéria-prima.…”

Resumo Com a existência de um limite entre o esgotamento dos recursos naturais e do crescimento econômico, evidencia-se a necessidade de encontrar meios para compatibilizar a conservação ambiental e o crescimento econômico. Nesse cenário, desponta a gestão ambiental, que visa reduzir os impactos causados ao meio ambiente advindos das atividades econômicas das empresas. Cumpre destacar que a geração de resíduos se apresenta como aspecto indissociável do processo industrial, que demanda investimentos para a sua adequada destinação final. Nesse contexto, o objetivo com este trabalho foi analisar os custos ambientais relacionados com a gestão de resíduos em indústrias químicas localizadas na região metropolitana de Porto Alegre. Os dados foram coletados por meio de uma pesquisa survey com gestores de 36 empresas da unidade de análise. As evidências coletadas facultaram a constatação de que os resíduos representam a maior parte dos passivos ambientais nas empresas investigadas. Além disso, grande parte dos respondentes declarou que nas empresas que desenvolvem suas atividades, os passivos são tratados por meio da comercialização dos resíduos gerados pelo processo produtivo, a fim de obter receita adicional. De acordo com 24 respondentes, os resíduos sólidos gerados em um processo produtivo são reaproveitados na produção de outro produto, e os gestores que responderam que não conseguem sequer gerar receita adicional, via comercialização de resíduos, tampouco aproveitar resíduos na fabricação de outro produto, alegaram dificuldade operacional para viabilizar o referido modelo, ou falta de organização interna para mapear os resíduos sólidos gerados no processo.Palavras-chave: Gestão de resíduos. Custos ambientais. Indústria química. Abstract With the existence of a limit between the exhaustion of natural resources and the economic growth, it is highlighted the need to find ways to reconcile environmental conservation and economic growth. In this scenario, comes up environmental management, which aims to reduce the impacts to the environment arising from the economic activities of enterprises. It should be noted that the generation of waste is presented as an inseparable aspect from the manufacturing process, which requires investments for its proper disposal. In this context, the aim of this study was to analyze the environmental costs related to waste management in chemical industries located in the metropolitan area of Porto Alegre. The data were collected through a survey research with managers of 36 companies unit analysis. Evidence collected provided the realization that the waste represent most of the environmental damage in the investigated companies. In addition, most respondents stated that in companies that develop their activities, liabilities are treated through the marketing of waste generated by the production process in order to obtain additional revenue. According to 24 respondents, the solid waste generated in a production process are reused in the production of another product, and the managers who responded that they cannot even generate additional revenue via marketing waste, either take advantage of waste in the manufacture of another product, alleged operational difficulty to enable that model, or lack of internal organization to map the solid waste generated in the process.Keywords: Wastes. Environmental economics. Chemical industry.

“…In agriculture is the pollution produced by solid waste plants and animals, but which may be reusable in other activities [13]. In the case of the rice sector has been implementing environmental impact reduction procedures, since they come from productive system externalities [14]. Among all residues coming from an agro-industry where the production of rice is processed, there are rice husk and ashes.…”

“…[15] composting is one of the most used destinations for this residue. The next step would be reusing residues generated after the manufacturing process of other products and using them in other areas like inputs (rice husk) [14].…”

The construction market is very growing, leading to the emergence of new technologies and materials, and a growing need for sustainable products for the construction process, and the call for quality of life we present the description of a new option alternative materials for environments that require careful with the acoustics. The research covers the development and incorporation of new material in construction, with the potential acoustic, from tests and measurements with calibrated decibel meter called. We also used the ceramic tiles pre-molded, used for making floors or ceilings in buildings and homes. The methodology used for the development of this research was characterized as literature, exploratory, descriptive, qualitative and quantitative, alternative and affordable. How after the analysis results of the tests performed it can be seen that the incorporation of rice hulls of agglomerated to form ceramic tiles, possible reductions in noise levels on the order of 8 dB (A) than the traditional construction of the buildings, and then an excellent material. This research contributes to the construction so that presented a description of a new product developed from a conventional material, originating in agriculture, waste rice husk and its incorporation during the construction of buildings and home, with the potential acoustic observed from tests and measurements with calibrated decibel meter called.

“…Rice hulls account for approximately 20% by weight of the seeds, generating millions of MT of waste every year (Stracke et al, 2018). These residues, if not disposed properly, are sources of environmental pollution as they are difficult to degrade (Saidelles et al, 2012). Studies have shown that rice residues can be used to improve shrimp and fish culture.…”

Aquaculture Full-length research articleUtilization of rice byproducts as carbon sources in high-density culture of the Pacific white shrimp, Litopenaeus vannameiABSTRACT -This study was conducted to evaluate the effect of rice byproducts on water quality, microbial community, and growth performance of L. vannamei juveniles. Shrimp of 0.98±0.10 g body weight (BW) were reared in 49 tanks of 1.5 m 3 under 127 animals m −2 for 77 days. Rice bran, rice grits, and rice hulls were mixed into five different fertilizers varying their fiber content (90, 110, 150, 200, and 250 g kg −1 ) and compared against sugarcane molasses (MO) and unfertilized tanks (UNF). Rice byproducts and MO were applied in water three times a week at a fixed rate of 4.5 g m −3 . Water salinity, pH, temperature, and dissolved oxygen reached 43±2 g L −1 , 8.03±0.32, 30.2±0.90 °C, and 5.03±0.53 mg L −1 , respectively. Settleable solids (SS) were higher in tanks fertilized with rice byproducts (from 2.5±1.0 to 3.1±1.1 mL L −1 ) and MO (3.4±1.0 mL L −1 ). Total ammonia nitrogen (0.19±0.09 mg L −1 ), nitrite (5.97±2.04 mg L −1 ), and nitrate (1.29±0.48 mg L −1 ) were kept low without any significant differences among treatments. The concentration of heterotrophic bacteria and fungi was significantly higher in rice byproducts compared with MO. Water fertilization had no effect on final shrimp survival (85.5±9.5%), weekly growth (0.72±0.11 g), and feed conversion ratio (1.59±0.10). Tanks treated with rice byproducts, except with 90 g kg −1 fiber, resulted in a higher final shrimp BW (from 9.04±1.56 to 9.52±1.89 g) compared with MO (8.75±2.14 g) and UNF (7.74±1.48 g). Gained yield and feed intake were significantly higher for tanks treated with rice byproducts than with UNF. A mix of rice byproducts can be equally or more effective as carbon sources to shrimp culture than MO.
