“…Como demonstração no gráfico, os dados apresentados permitem evidenciar que 24,5% de matéria prima se transformam em resíduos de madeira ao final do processo. Pôde-se observar que essa perda é significativa ao compará-la com estudos realizados por Caetano et al (2017), em uma marcenaria de pequeno porte em Cariacica-ES, na qual se constatou uma perda superior a 20%.…”

As políticas ambientais atualmente estão exercendo uma forte pressão sobre todos os segmentos geradores de resíduos sólidos. Dentre esses, está à indústria moveleira, pois produz grande quantidade e diversidade de resíduos de madeira, cuja exploração e desperdício desencadeiam uma série de impactos negativos para o meio ambiente e para a saúde pública. Este trabalho teve por objetivo, através de estudo realizado em uma oficina de marcenaria, localizada na cidade do Recife-PE, pertencente ao Tribunal de Justiça de Pernambuco, propor um sistema de gerenciamento de resíduos madeireiros gerados nessa oficina em conformidade com as leis e resoluções vigentes, com finalidade de minimizar os impactos ambientais negativos oriundos dos resíduos produzidos neste setor. A metodologia utilizada se fez através da coleta de dados por meio de observação direta, entrevista e aplicação de questionário contendo questões referentes aos tipos e desperdícios de matérias-primas, equipamentos usualmente utilizados, cadeia produtiva e os tipos de resíduos gerados nesse processo. Os compensados, os painéis de divisórias e de MDF são a principal matéria-prima da marcenaria. Predominou-se a compra de compensados (61%), seguido de painéis de divisórias (30%) e MDF (9%). Os equipamentos utilizados foram a serra circular, a plaina, a lixadeira e a furadeira. Os resíduos gerados durante o processo produtivo foram o retraço (33%), a serragem (33%), o cavaco (16,67%) e a maravalha (16,67%). Verificou-se que o modelo atual de gerenciamento de resíduos era a doação, faltando ações para a redução de geração e de seu aproveitamento. O resultado mostrou que o nível de desperdício da matéria-prima em forma de resíduos é bastante significativo, girando em torno de 24,5%.

“…Part of these raw materials is lost in manufacturing in the form of waste, which is estimated at 10% of the total mass [21]. However, a study carried out at a medium-sized furniture industries in Espírito Santo showed a percentage loss of over 20% [22].…”

Proper management of wood waste (WW) from the furniture industry has become an important issue. Life-cycle assessment (LCA) is a tool that is widely used for identifying environmental gains in WW management strategies. Thus, the aim of this research was to perform a comparative LCA, analyzing the environmental aspects and impacts of different WW management scenarios generated in the furniture industry in the state of Espirito Santo, Brazil. To conduct the study, five scenarios were designed: medium-density fiberboard (MDF) production (Scenario 1), medium-density particleboard (MDP) production (Scenario 2), solid ceramic brick production (Scenario 3), heat production in the ceramics industry (Scenario 4), and landfill disposal (Scenario 5). The results showed that compared to Scenarios 3 and 4, Scenarios 1 and 2 are potentially more favorable for disposing of WW. Scenario 1 achieved more environmental benefits in all of the impact categories evaluated. Notably, 1 m3 of MDF stores 1080 kg CO2 eq/m3, which results in a net impact of −849 kg CO2 eq/m3 of MDF. Scenario 5 is the least favorable practice. This research designs scenarios that contribute to reductions in the demand for virgin sources and increases in environmental gains.

“…A study by the Brazilian Association of Public Cleaning and Special Waste Companies cited in ABRELPE (2016) indicates that between 2014 and 2015 an approximate increase of 12,692 tons of MSW per day was generated in the Amazon and, of 450 municipalities, only 258 in the northern sub-region of Brazil maintained the selective collection programme, revealing a significant risk to the developmental advance in the scenario under review. Caetano et al (2017) insists that, in the treatment of solid waste, its weight and volume before and after treatment should be measured to gather important information on the efficiency of the procedures applied, the amount of waste that would eventually go to landfill and the average useful life of these units.…”

Inadequate disposal of urban solid waste (USW) contaminates the soil, groundwater, bodies of surface water and the atmosphere, due to the emission of polluting gases. It causes urban flooding due to the obstruction of storm-water drainage systems caused by accumulated USW. Carried by rainwater, it also, among other environmental events, affects the macro- and micro-climate, raising the local and global temperature. In this scenario the present study asks how innovation in the management of urban solid waste can contribute to social and environmental innovation. The general objective of this work was to study the management of USW in the Amazon sub-region, given the advent of social and environmental innovation. To obtain its results, it took the following as its specific objectives: (1) interpreting the current management of the USW of the sub region of interest; (2) describing the ultimate destination of the USW; and (3) proposing models of socioenvironmental innovation for the management of USW in the local sub-regions. The case study method was applied, using the necessary procedures. It was observed that the management of USW in the studied sub region is restricted to public power facilities, where it employs few processes or technologies. Regarding the final disposal of the USW, the municipalities have not instituted any separation of recyclables from waste products and hence they send all domestic and industrial waste to landfill sites as if nothing was recyclable. In addition, most municipalities continue to dump contaminants in their old sites, pending decisions to close them and ask responsible bodies to supervise them. This paper is an academic contribution to the improvement of waste management. It proposes innovative USW management practices, based on the principle that the Polluter Pays; initiatives that favour socioenvironmental innovation must be substantiated. This research is of interest to scholars working on sustainability and to managers concerned with issues related to socioenvironmental management.
