AbstractThe implementation of circular economy in wood industries is an effective way for future sustainable development. The wood industries in China are not in the direction of circular economy approach due to less availability of assessment/calculation data of pollutants as per life cycle assessment (LCA) criteria. The present study focuses on the calculation of emission and pollutants from wood industries as per LCA; the emission and pollution data were collected from fiberboard Medium-density fiberboard (MDF), plywood and particleboard (PB) production. The comparative analysis of dust emissions, industrial waste gases and chemical oxygen demand (COD) were performed among three wood industries. The results revealed that the fiberboard industry was the highest emitter of dust, industrial waste gas and COD; and particleboard industry was the least emitter. Further, results indicated that pollutant index of wood industries were significantly changed between 2015 and 2017; the industrial waste water discharge increased five folds and the COD, dust and industrial gases increased two times. This study provides with the emission and pollutants data of wood industries as per LCA to promote the sustainable development for circular and low carbon economics.

Antecedentes: El sector de la construcción es uno de los sectores económicos en Colombia con mayor crecimiento, generando grandes cantidades de residuos como producto del proceso de construcción, y/o demolición, o en su defecto en la fabricación de los materiales de construcción. Objetivo: facilitar el acceso a información académicocientífica actualizada sobre reciclaje de residuos industriales y su aplicación en la fabricación de materiales de construcción. Así mismo se emplea el término de economía circular, el cual hace referencia a la integración de las actividades de reducción (consumo de energía y residuos), reutilización y recuperación durante la producción, el intercambio y consumo. Conclusión: además de reducir la contaminación generada por los residuos de los sectores productivos, con el aprovechamiento de los subproductos ha sido posible mejorar ciertas propiedades tecnológicas de estos materiales de construcción.Palabras Clave: economía circular, materiales de construcción, nutriente tecnológico, reciclaje, residuos industriales.AbstractBackground: The construction sector is one of the economic sectors with the highest growth in Colombia, generating large amounts of waste as a result of the construction process, and / or demolition, or otherwise in the building material manufacturing. Objective: to facilitate the access to updated academic-scientific information on recycling of industrial waste and its application for the building material manufacturing. Moreover, the concept of circular economy is used, which refers to the integration of the reduction activities (energy consumption and waste),reuse and recycling during the production, exchange and consumption. Conclusion: in addition to the reduction of the pollution generated by waste from the productive sectors, certain technological properties of these building materials have been improved through the use of waste. Keywords: circular economy, building materials, technological nutrient, recycling, industrial waste.

In recent years, china are paying attention to the development of the circular economy and the ecological industrial parks, industry, as the industry of the largest emissions of industrial waste, the circular economy is more concern by people. The recovery transport process of industrial waste recycling is the important part of the industrial circular economy, reasonable scheduling solution is the effective means to improve the recovery and processing speed of industrial wastes and make the cost of recycling lower. In this paper, through analysis and research the recovery transport links of industrial waste recycling, points out that the vehicle scheduling problem of industrial waste recycling is the scheduling problem combined full load with not-full load, and for this problem, build vehicle scheduling optimization model, use ant colony optimization algorithm to solve it, and that achieved good results.

The circular economy is a process through which elements that have already been used are reincorporated and given a second use so that they can reduce the consumption of virgin raw materials. This article shows how, from the reuse of an agro-industrial waste such as corn husks, a biomaterial can be developed that manages to standardize the properties of materials such as paper and cardboard, thus allowing the development of single-use products that replace the excessive expense of materials such as polymers. In this article, it will be possible to show how from the process of transforming an agro-industrial waste into a raw material base, it is possible not only to reduce the number of raw materials discarded but also to redesign a product that not only contributes to the environmental component but also facilitates the processes of economic sustainability when generating products. As a practical case, a comparison is made between traditional fast-food packaging and how from these, a new packaging proposal can be generated, which starts from the principles of circular economy and complements sustainable design processes to make more efficient manufacturing of the mentioned product.

A circular economy (CE) is proposed to mitigate resource shortage and environmental pollution. Given the inevitable conflict between the new development mode and traditional economic benefits, practical experience shows that CE implementation needs the support of outside forces, such as government policy interventions or environmental organisations’ propaganda guidance. On the basis of existing studies, the present work establishes a systematic economic model in accordance with the characteristics, objectives and principles of CE. The equilibrium solution and critical condition of government and non-government participation models are obtained through game analysis. We select the industrial waste water circulation of some provinces in China to illustrate the feasibility and effectiveness of the proposed model. Overall, our results indicate that the gap between the critical price and unit processing cost determines the promotion of CE and government intervention. Moreover, government intervention is critical to building a waste management department in its early stage.

Development of low-cost contaminant sorbents from industrial waste is now an essential aspect of the circular economy since their disposal continues to threaten ecological integrity. Semicoke (SC), a by-product generated in large quantities and described as solid waste from gasification of low-rank coal (LRC), is gaining popularity in line with its reuse capacity in the energy industry but is less explored as a contaminant adsorbent despite its physical and elemental carbon properties. This paper summarizes recent information on SC, sources and production, adsorption mechanism of polluting contaminants, and summarizes regeneration methods capable of yielding sustainability for the material reuse.
