“…Pulp and paper industries are producing an enormous amount of pulp annually to meet the ever-growing demand for papers and packaging materials [1][2][3]. Statistics also revealed that the global paper and cardboard production rose from 391.2 to 410.9 million metric tons from the year 2008 to 2016 [4].…”

In this study, we utilized lime mud waste from paper mills to synthesize calcium hydroxide (Ca(OH)2) nanoparticles (NPs) and investigate their application for the removal of phosphorus from aqueous solution. The NPs, composed of green portlandite with hexagonal shape, were successfully produced using a precipitation method at moderately high temperature. The crystal structure and characterization of the prepared Ca(OH)2 nanoparticles were analyzed by field emission scanning electron microscopy, Fourier transform infrared spectroscopy, and X-ray diffraction. The effects of Ca(OH)2 NP dosage and contact time on removal of phosphorus were also investigated. The results show that the green portlandite NPs can effectively remove phosphorus from aqueous solution. The phosphorus removal efficiencies within 10 min are 53%, 72%, 78%, 98%, and 100% with the different mass ratios of Ca(OH)2 NPs/phosphorus (CNPs/P) of 2.2, 3.5, 4.4, 5.3, and 6.2, respectively. Due to the efficient phosphorus removal, the calcium hydroxide nanoparticles (CNPs) could be a potential candidate for this application in domestic or industrial wastewater treatment.

“…Papermaking is an ancient art, and has a long history . It appears to have begun in China about a century after the start of the Christian era, and this invention historians have attributed to Cai Lun in 105 A.D. At that time, wood was widely used as papermaking material because of its unique structure and it's excellent mechanical properties . With the social progress and the rapid development of science, the emergence of various functional papers lead to papermaking industry, still very relevant in today's economy .…”

“…To minimize such environmental issues, a variety of methods have been proposed by many researchers to reduce the consumption on timber and industrial pollutants . For example, the use of recycled waste paper as raw material for recycling of paper industry has been employed and considered as a common way to this end.…”

The paper industry is closely related to our daily life. Vast quantities of paper requirement worldwide lead to astonishing lumber consumption and environmental pollution. So the exploration of alternative paper‐like material should be of great importance. Here, we reported the preparation of a kind of environmentally friendly clay‐based polymer composite paper‐like film by incorporation of a kind of nanometer sized natural clay crystals, in this case attapulgite (ATP), into degradable poly(vinyl alcohol) (PVA) only though a simple blending and subsequently casting method. X‐ray analysis shows that no changes in the crystalline structure of ATP were observed in the PVA matrix. Even with a high content of clay crystals in composites (50 wt %), the resulting ATP‐PVA composite films (named as APCF) show excellent flexibility and tensile strength up to 22.19 MPa. The doping of ATP also results in flame retardant of composites, making it ideal candidate for packing and also building decoration applications. Interestingly, the APCF are printable and also much tough and tensile. Due to the simple fabrication, nearly no pollution emission process and easily to be scaled up, the APCF have great potentials as a kind of alternative for paper materials for diverse applications. © 2017 Wiley Periodicals, Inc.

“…Pulp and paper mills have produced large amounts of pulp annually (He et al, 2009;Nurmesniemi et al, 2007;Zhou et al, 2012). As the second largest producer of paper globally, for instance, China produces approximately 50 million tons of papers per year that accounts for over 50 wt% in terms of the global yield (He and Barr, 2004).…”
