The objective of this research is to investigate the effect of incorporating graphite filler on mechanical, thermal and morphological properties of wood recycled plastic composites (WrPC). WrPC was prepared using recycled polypropylene (rPP), kenaf core, maleic anhydride polypropylene (MAPP) and graphite filler. The graphite content in WrPC is 3 phr. All materials were premixed manually and fed into a single screw extruder and compression molded to prepare mechanical test specimens. The effect of graphite on tensile properties, impact strength, glass transition temperature (Tg) and morphologic

We face multiple water challenges: droughts, floods, crumbling infrastructure and disappearing natural hydrosystems. Technological interventions will help but these challenges also require social solutions and good governance. Identifying and implementing both technical and social solutions demands a resilient water research and policy community (WRPC). The WRPC must include diverse perspectives as the challenges increase in intensity, frequency and scope and as decision processes accelerate. Will the WRPC be able to effectively address this evolving water context? Possibly, but we argue that

A demand to replace an easily combustible wood with wood–plastic–rubber composite with better thermal performance than wood is at its peak globally. Wood-based composite materials in the form of wood–polymer composite (WPC) have emerged as new materials that can replace wood to produce wood products for various use. The use of recycled polymers as biodegradable polymer blended with fiber particles, waste tire powder, and other substances to manufacture new products known as wood–rubber–plastics composite (WRPC) for building construction and other different applications, has piqued the interest

Abstract Water resources carrying capacity (WRCC) is an important component of the carrying capacity of regional natural resources. It is a restrictive index indicating whether a region can support the coordinated development of its population, economy, and environment. In order to solve the problem that WRCC varies with the supporting capacity of, load on, and capacity for regulation of the water resources, this study establishes the relationship between WRCC and the level of socio-economic development (carrying level) and then develops a WRCC evaluation model by analyzing the connotations, c

The evaluation of water resource carrying capacity (WRCC) is crucial for guiding regional water management. This study established a WRCC evaluation index system and standards for the middle and lower Yangtze River, covering four subsystems: water resources, and social, economic, and ecological dimensions. The study improved the matter–element extension model by introducing triangular fuzzy numbers. The enhanced model was then used to assess the WRCC of seven provinces in the middle and lower Yangtze (2015–2023). Furthermore, GIS was used to examine the spatiotemporal variations and driving fa

The water resources carrying capacity (WRCC) strongly determines the agricultural development in arid areas. Evaluation of WRCC is important in balancing the availability of water resources with society’s economic and environmental demands. Given the demand for sustainable utilization of agricultural water resources, we combine the water stress index and comprehensive index of WRCC and use multi-source data to evaluate agricultural WRCC and its influencing factors at the township scale. It makes up for the deficiencies of current research, such as the existence of single-index evaluation syste

The water resources carrying capacity (WRCC) is a crucial indicator for assessing the sustainability of regional development. This study integrates the gray water footprint (GWF) into the WRCC evaluation, constructing a comprehensive framework that encompasses five subsystems: water resources, society, economy, ecology, and climate. Using the CRITIC-TOPSIS model, the WRCC of Yunnan Province from 2012 to 2022 is analyzed, and a dynamic assessment is conducted through spatiotemporal hotspot and obstacle factor coupling analyses.

The assessment of the water resources carrying capacity (WRCC) is a prerequisite for socioeconomic sustainable development in Xinjiang. In this paper, a convenient and effective model is established for assessing the WRCC under the influence of social welfare and water use efficiency. Meanwhile, a pedigree chart for WRCC is put forward. Then the developed approach is applied to investigate the sustainable utilization of water resources i

With the growth of population, water security has become the worldwide problem combined with severe environment pollution, quick economic development and irrational water allocation. Based on sustainable development, Water resources carrying capacity (WRCC) driven from physics originally has been proposed to solve it. The measurement of WRCC can tell decision-makers that how much population the water resource can feed, what degree water resources can support the economic and so on. Because the decision-makers can make adaptive decisions based on the correct evaluation of WRCC, the ways of the

Water resource carrying capacity (WRCC) is an important metric for regional sustainable development in China. It is defined as the difference between the total water supply and demand. The North China Plain (NCP) currently faces a serious water shortage if the WRCC is not managed at a sustainable level. This study focuses on applying system dynamics (SD) methodology to evaluate different water use scenarios and their associated WRCC for the NCP. System characteristics of local water resources and demand in the NCP are captured and simulated using VENSIM® software. A SD model of the WRCC is con
