This paper aims to investigate the potential use of recycled tire rubber in concrete. In Malaysia, rubber consumption of tires in January – June 2014, rose up to 8.4% from 0.388 million tonnes. These numbers keep on increasing year-over-year with the numbers of vehicles, as do the future problems relating to waste tires. Over the past few years, a number of researchers have studied on incorporated the waste tires into cement based materials. In an attempt to reduce the magnitude of this issue, recycled tire rubber has gained interest in concrete improvement. The used of recycled tire rubber in the reinforcement in concrete is considered as value added materials for sustainable development by reusing waste materials. It is believed that using waste tire rubber in concrete could be an alternative way to replace fine and coarse aggregate (sand and gravel) in improving the properties of concrete. Rubberized concretes can be used in architectural applications such as side walk pavement, nailing concrete, in road constructions where high strength is not necessary, outdoor playground mat, in wall panels that require low unit weight, in sound barriers as sound absorbers, and in railroads to fix the rails to the ground.

Climate change (along with other factors) has caused an increase in the proliferation of brown algal mats floating freely along the Atlantic Ocean since 2011. These brown algae mats are composed of sea plants from the Sargassum genus. The gargantuan agglomeration of biomass flows alongside currents and lands in beaches belonging to the Eastern coasts of the Mexican Caribbean and several other countries in the region. These events, dubbed golden tides, harm the local economy and environment. Current elimination approaches involve the mechanical harvesting of the Sargassum and ultimate landfill disposal. However, explorations into the commercial application of other brown algae have elucidated the potential of Sargassum as a feedstock for valorization. This review informs the trends, challenges, and opportunities presented by the coastal invasion of this biomass. Primarily, the potential use of this material is as a precursor in biorefineries where multiple value-added products are generated concurrent with the ultimate production of biofuels.

Sugarcane leaves (SLs) are a bio-waste from sugar production industry. To explore the value-added SLs, the SLs were used raw materials of activated carbons (ACs) by steam activation and their electrochemial properties were investigated for supercapacitor applications. The synthesis of ACs from the SLs consisted of two steps; carbonization at 500oC and steam activation. The synthesis condition was optimized by varying activation temperature (800 and 850oC) The porous structures were thoroughly formed on the surface after steam activation and the surface areas were reached to 630 and 639 m2 g-1 at the activation temperature of 800 and 850oC, respectively. The SLs-derived ACs activated at 800oC assembled in coin cell using organic electrolyte showed the highest specific capacitance of approximately 16 F g-1 with a capacitance retention of 62% when the current density increased to 1.5 A g-1. Even though there is a room to improve the electrochemical properties such as optimization of porosity and removal of inorganic component, the SLs show a potential use as raw materials of ACs for supercapacitor applications.

Raw materials from renewable natural resources for industrial applications are in high concern in recent industrial research. Researchers invest their time in the management of waste as well as the conversion of waste to wealth. In that line, the production of biofuels including biodiesel, and value-added products from non-edible oil sources as well as from the generated waste biomasses, are in the tilt of research in recent times. Preparation of different oleochemicals such as grease, resins, soap, lubricants, etc. from vegetable oils, and utilization of seed cake as fertilizer, animal feed, medicine, etc. are encouraged as a part of the generation of waste to wealth as per today’s environment is concerned. In recent days, various reports on the production of biodiesel and other oleochemicals from non-edible oil sources are published in various scientific journals. Yellow oleander (Thevetia peruviana) is a tropical shrub which produces a toxic non-edible fruit containing a high percentage of seed oil (up to 67%), protein (30-37%) as well as other medicinally important phytochemicals. It is attracting the researchers worldwide for the production of biodiesel, various oleochemicals, medicine, animal feed, etc. In this study, biodiesel and various value-added products synthesized from Thevetia peruviana oil and cake are reviewed to generate and popularize the potential use of yellow oleander seed for various industrial applications and accordingly, for substantial growth in cultivation for commercial-scale requirements.

Sweet cherries are processed in various ways, leading to significant amounts of underutilized by-products that can potentially be used as a source of bioactive compounds, including antioxidants. The present study focuses on identifying ways to exploit bioactive compounds from sweet cherry skins, namely the extraction, microencapsulation, and functionalizing of some food product to obtain added value. The anthocyanins from skins were extracted and encapsulated in a combination of whey proteins isolate and chitosan by freeze-drying, with an encapsulation efficiency of 77.68 ± 2.57%. The powder showed a satisfactory content in polyphenols, of which anthocyanins content was 14.48 ± 1.17 mg cyanidin 3-glucoside/100 g dry weight (D.W.) and antioxidant activity of 85.37 ± 1.18 µM Trolox/100 g D.W. The powder was morphologically analyzed, revealing the presence of coacervates, ranging in size from 12–54 μm, forming large spheresomes (up to 200 μm). The powder was used as a functional ingredient to develop two value-added food products, namely yoghurt and marshmallows. The powder was tested for its prebiotic effect on L. casei 431® in the yoghurt samples during 21 days at 4 °C, when a decrease in viability was found, up to 6 log CFU·g−1. The anthocyanins and antioxidant activity decreased in yoghurt and increased in marshmallows during storage time. The obtained results support the potential use of extracts from underutilized sources in the development of functional ingredients and value-added food products.

The degradation dynamics of lignin and cellulose were analyzed by means of a solid state biodegradation experiment, using residues from the essential oil extraction of the Palo Santo tree (Bursera graveolens). As such, two native Xylaria spp. and an exotic mushroom Trametes versicolor were incubated on the spent substrate (Residues of B. Graveolens, BGR’s). The relatively high lignin and cellulose contents of the BGRs (9.1% and 19%, respectively) indicated the potential of this resource for the production of methane (biogas) and ethanol. However, the degradation of the lignin and cellulose content could be traced back to the relatively high activity of the enzymes laccase, cellulase, and xylanase, produced by the fungi. The results showed that laccase (30.0 U/L and 26.6 U/L), cellulase (27.3 U/L and 35.8 U/L) and xylanase (189.7U/L and 128.3 U/L) activities of Xylaria feejeensis and Xylaria cf. microceras were generally higher than T. versicolor (9.0 U/L, 29.5 U/L, 99.5 U/L respectively). Furthermore, the total carbon (TC: 47.3%), total nitrogen (TN: 1.5%), total phosphorus (TP: 0.2%) and total potassium (TK: 1.2%) dynamics were analyzed during the experiment and their importance for the degradation process highlighted. The results of this work might serve as guidance for future studies in dry forest areas, while furthering the understanding of the potential use of native fungi as ecologic lignocellulosic decomposers and for industrial proposes.

Ramie (Boehmeria nivea L.) is usually cultivated as a fiber crop, but it is also well known for its potential use in animal feeding with viable commercial applications. In this study, the phenolics profile as well as cellular antioxidant and antiproliferative activities were investigated in free and bound fractions of six different vegetative parts from Boehmeria nivea L. The highest total phenolic content was observed in bud (4585 ± 320 mg GAE/100 g DW), whereas root and petiole had the lowest total phenolic contents, 442.8 ± 9.8 and 630.9 ± 27.0 mg GAE/100 g DW, respectively. Likewise, phloem had the most abundant total flavonoids (2755 ± 184 mg CE/100 g DW), whereas the lowest flavonoid contents was found in root and petiole, 636.9 ± 44.2 and 797.4 ± 87.6 mg CE/100 g DW, respectively. Xylem and bud depicted remarkable antioxidant and antiproliferative activities, which could be explained by their diverse phenolic composition, especially chlorogenic acid and epicatechin. The Boehmeria nivea L. plant might be a valuable resource for high value-added phenolic compounds used in food and non-food industries.

The increasing amount of food waste throughout the world is becoming a major problem for waste management plants. The food waste produced amounts to 1.3 million tons a year. This is a resource that could be used for production of new products. Bioeconomy is a method that can help achieve production of value-added products that use local resources and waste to manufacture products efficiently. This by-product causes environmental pollution due to decomposition. However, food byproducts like potato peel have essential organic matter. So this review introduces the potential use of potato peel as food preservative, pharmaceutical ingredient, renewable energy, and animal feed to promote ecofriendly food industries. In this review are looking at possibilities to use potatoes for production of new materials, such as bioplastics, antioxidants, proteins, instead of their conventional use for food production.
