Palm oil is one of the two most important vegetable oils in the world’s oil and fats market. The extraction and purification processes generate different kinds of waste generally known as palm oil mill effluent (POME). The environmental impact of POME cannot be over emphasized; hence the need for treatment measures to reduce these impacts before discharge. Therefore, this paper reviews the proc...

Utilisation of palm oil mill wastes to make soil conditioner through anaerobic co-composting is feasible and has the potential to maintain the natural resources, and to reduce the impact on environmental quality in the future. Co-composting process uses pressed-shredded-grinded empty fruit bunch (EFB) with activated sludge (AS) from the pond system of a palm oil mill as a suitable option for or...

Oil palm ash (OPA), a bio-agricultural waste from oil palm mills, was subjected to high-energy ball milling for 30 h and was converted into a nano-structured material. The nano-structured OPA was characterized for its particle size and crystallinity index by using Transmission Electron Microscopy (TEM) and X-ray Diffraction (XRD) analysis. The crystallite size obtained from TEM and XRD was foun...

A field survey was conducted in Okomu Forest Reserve Edo State, to assess the diversity and seasonal dynamics of arthropod species selected land use systems (Okomu national park, rubber plantation oil palm plantation). Samplings arthropods were carried out between February September 2020, collected by hand picking sweep net each sampled plots at 25 m x study area. Insects encountered killed pre...

The company’s market value or firm (FV) is essential for shareholders to maximize wealth (Jensen, 2010). FV a function of various factors, especially company-specific which are the main drivers (Chen et al., 2019). This study aims estimate impact stock returns (SR), return on assets (ROA), leverage (debt-to-equity ratio, DER), and total (SIZE) proxied by price-to-book (PBV) methods data analysi...
