The amount of residues generated by agriculture, industrial, or urban activities continuously increases and, consequently, demands several methods for their correct management. The incorrect disposal can cause, in specific cases, environmental contamination by heavy metals or leaching as well as promote the spread of diseases as insect proliferation. Commonly, landfilling, incinerating, composting, or energy/fuel generation can control the disposal or reuse of residues. Among the methods for the reuse of wastes, the incorporation of residues as fillers in polymer composites has emerged as a distinct field. Some composites can potentially mitigate leaching compounds or improve mechanical, thermal, and acoustic properties. However, these improvements are a challenge to promote the use of waste fillers. Thus, this study aims to provide a state of view regarding a variety of wastes used as fillers in polymer composites and different methods to reach mechanical reinforcement as well as improve thermal conductivity and acoustic attenuation for future researches.

“…25 The other characteristic peaks were 1366 cm À1 (C H bending), 1321 cm À1 (O H plane bending), 1146 cm À1 (C O, C O C, C C ring stretching band), 1032 cm À1 (C O C glycosidic ether band, C O C pyranose ring stretching vibration), and 1512 cm À1 (C C vibration in aromatic ring). 25,26 According to the filtrate spectrum, the O H group in the fiber was responsible for the absorption bands at 3428 and 3340 cm À1 , while the vibration at 3340 cm À1 was caused by an intramolecular hydrogen bond. 26 In addition, the peak at 2225 cm À1 represented asymmetric alkyne stretching.…”

“…In LMF, these two peaks moved towards the low frequency 1585 and 1147 cm À1 , indicating that a strong hydrogen bond was formed between the filtrate and PVA and PEO molecules, which made each component have good compatibility. 10,25 The two absorption peaks near 1005 cm À1 combined into a sharp peak. This might be due to a certain degree of copolymerization reaction after the filtrate and PVA were blended, leading to the fusion of absorption peaks.…”

This work was aim to prepare biodegradable mulching film from biomass materials to reduce the environmental pollution caused by plastics. Black tea waste was divided into two parts and combined with degradable materials such as polyvinyl alcohol and cellulose to prepare two degradable mulching films: liquid mulching film (LMF) and solid mulching film (SMF). The optimum formula was developed after studying the effects of various components of degradable mulching film on mechanical properties in both dry and wet circumstances. The properties of LMF and SMF were characterized and tested by scanning electron microscope (SEM), Fourier transform infrared spectrometer (FTIR), light transmittance test, contact angle test, water resistance test, artificial accelerated aging test, and degradation performance test. The results demonstrated that LMF and SMF had good mechanical properties, resistance to ultraviolet light, water resistance, aging resistance, and biodegradation. Using tea waste to prepare mulching film material has the advantages of no pollution, easy biodegradation, and good biocompatibility.

“…The development of industry has led to the accumulation of heavy metals in sewage. [1][2][3] Heavy metals can cause serious disease if they accumulate in the human body because they are not biodegradable. [4][5][6] To solve this problem, researchers have developed numerous methods to eliminate heavy metal ions.…”
