“…Os conceitos de resíduos sólidos e de lixo podem variar conforme a sua aplicação (HEMPE, NOGUEIRA, 2012): lixo é todo material inútil resultante de atividade humana ou cuja existência no meio é tida como nociva (SILVA, 2003), ou seja, é aquilo que não se quer mais e joga fora (SCUPINO, 2015); resíduos sólidos são todo e qualquer material descartado e indesejável, resultante da ciclagem de materiais pelos sistemas produtivos humanos (FADINI;FADINI, 2005).…”

Um dos principais causadores dos problemas socioambientais são os resíduos sólidos (RS), devido ao consumismo desenfreado e à sua destinação inadequada. Assim, com vistas a minimizar os efeitos causados pela má gestão dos RS, o princípio dos 3 R's (reduzir, reutilizar e reciclar) tem sido um dos temas trabalhados em projetos de Educação Ambiental (EA) nas escolas. Com o passar dos anos, novos R's foram sendo inseridos nessa metodologia, a fim de conscientizar a sociedade desde a não geração dos resíduos até a reciclagem. Nesse contexto, o presente artigo buscou realizar uma análise, da teoria à prática, dos R's no âmbito da EA nas escolas e o caminho a ser percorrido para que estejam inseridos dentro da escola.

“…Waste that is high in organic matter requires treatment to reduce the amount of organic waste before discharging into recipient waters. Chemical Oxygen Demand (COD) is a major parameter used as routine surrogate tests for measuring the load of organic carbon into the environment [16]. Also, COD is a cheap method for the determination of organic load in waste water [17].…”

The refluxing time is a significant consideration in synthetic study, because it could reflect the kinetics of the reaction process. Synthetic Organic Chemicals (SOCs) are man-made carbon-based compounds that are not likely to evaporate into the atmosphere and hence they could get into aquatic water bodies through terrestrial runoff or discharge from factories. Therefore, this paper investigated the effect of refluxing time and kinetics of Synthetic Organic Chemicals (SOCs) removal in aqueous solutions by carbonized and surface-modified carbons made from Nipa Palm (<i>Nypa Fruticans </i>Wurmb) fronds using chemical oxygen demand (COD) as the measurement parameter. The data showed a rapid reduction of the COD of the SOCs contaminated solutions from 30.19 to 93.46% for PCC, 27.44 to 65.58% for AAC, 41.84 to 98.22% for BAC and 56.71 to 95.16% for CAC between 10 to 60 mins. Optimum reduction was achieved within 20 min of heating the solutions at 150°C. The rapid COD reduction observed for n-propanol indicates that COD is a rapid, inexpensive means of determining organics in water. Kinetic assessment of the results showed that, pseudo-first order kinetic equation did not provide a very good description of COD reduction of the SOCs in aqueous solution by the Nipa palm derived carbons. However, Nipa palm had been adjudged as a beneficial, eco-friendly and locally available source for the development of activated carbon for elimination of organic pollutants in domestic and industrial wastewaters.
