Calcium pyrophosphate (CPP) was prepared by a simple precipitation method using avian eggshell waste as a low-cost alternative calcium precursor source. The synthesized CPP powder was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM/EDS), thermogravimetric analysis (TGA), and Fourier transform infrared spectroscopy (FTIR). The results indicate that pure b-CPP nanocrys...

Potato protein liquor (PPL), a side stream from the potato starch industry, is normally used as fertilizer. However, with more than 100 g/L of sugars, 20 g/L of Kjeldahl nitrogen and Chemical Oxigen Demand (COD) of 300 g/L, it represents serious environmental challenges. The use of PPL for fungal cultivation is a promising solution to convert this waste into valuable products. In this study, PP...

L(+)-LACTIC ACID is a commonly occurring organic acid. It is widely used in the food and food-related industries, and has the potential to be used for the production of biodegradable polymers, solvents and oxygenated chemicals. Lactic acid can be produced by both bacteria and fungi, however it is currently produced from sugar-containing materials by bacteria such as Lactobacillus and Lactococcu...

A predictive model for powder compaction has been developed that incorporates unprecedented flexibility to design powder press tooling and reliable powder pressing processes. Sandia’s finite element (FE) toolkit comprises the heart of the modeling software, and a unique concept was developed to design a variable dimension and parameter template to easily build/design dies/components on a comput...

The present study reveals that a potent laccases producer Pycnoporus cinnabarinus produces higher quantity of laccases in the Coll et al. Medium (M1 medium) and Potato dextrose broth medium (M4 medium) containing agricultural waste ‘wheat bran’ (1%w/v) after a great comparative study among the five laccases production media namely Coll et al. medium (M1 medium), Olga et al. medium (M2 medium), ...

Nanostructured iron oxide powder that has been recovered from waste pickling liquor unit of steel industry was studied for oxidation catalytic applications. In this research, the powder was characterized by X-ray diffraction (XRD) and transition electron microscopy (TEM) for determination of phase structure, morphology and particle size. Furthermore, the specific surface area of the powder was ...

The superior oil absorption capacity of recycled polypropylene (PP) fiber and waste tire powder were used to recover spilled engine oil. We used ASTM F726-99 method to evaluate oil adsorbing capability of PP fiber and found it to have a large, rapid oil sorption capacity. However, its lack of elasticity dramatically limited that capacity after repeated use. Tire powder, which absorbs less oil m...

Low calcium intake, poor calcium absorption, excessive calcium losses, or some combination of these factors contribute to calcium deficiency diseases. Calcium insufficiency is associated with osteoporosis, hypertension and colon cancer among other diseases. For individuals who do not have access to milk and dairy products, do not tolerate them, or prefer not to consume them, plants may be alter...

Incorporating waste stone powders into the production of reactive powder concretes (RPCs) can be eco-friendly. Since high cementitious material content is used in producing RPCs, CO2, as a harmful greenhouse gas, was for carbonation curing this study. For purpose, limestone substituted by 0%, 18%, 36% and 54% silica sand specimens were cured water up to 90 days CO2 chamber 48 hours. The physica...
