Solid waste management and its role in mitigating environmental degradation with special reference to recycling of wood wastes

Due to rapid industrialization, urbanization and population growth in India, solid waste generation has been increased to a large extent. In recent years,  disposal of solid wastes has caused serious environmental  hazards and economic problems.  India generates 1.45MT of wastes per day at present. Annual increase in overall quantity of solid waste is assessed at about 5% and nearly three-fourths of the waste is generated in urban areas. Municipal Solid Wastes (MSW) amount is e...

Techno-economic study of a Biomass Briquetting Unit

The present study analyses the ongoing efforts to solve the fuel crisis of The Western India Plywoods Ltd (WIP), a large wood-based panel industry in Kerala via fuel briquettes from wood wastes generated from its own various manufacturing units with a well proven technique called biomass briquetting. Saw dust and other wood wastes and residues from all types of primary and secondary wood processing operations are generally bulky in nature and are therefore expensive to store and transport. Al...

Evaluation of the Growth and the Nutritional Status of the Leaves and Roots of Moringa oleiferaunder the Influence of Organomineral Amendments in Humid Tropical Region

This study aimed to evaluate the influence of organomineral fertilizer on the growth and mineral composition of Moringa oleifera organs. The experiment included three doses of cow dung, three doses of mineral fertilizers and two doses combining mineral fertilizers and cow dung. Soil samples and samples of M. oleifera organs were analyzed. Results revealed the contribution of fertilizer to improve soil chemical properties, except pH. The best vegetative development was obtained with the d...

Characterization of briquettes produced from four lignocellulosic material admixtures using a hydraulic briquetting press (HBP)

The physical characteristics and combustion performance of briquettes produced from four lignocellulosic materials and its admixtures using a 5-ton HBP with a rectangular mould had been carried out.  The sole materials evaluated include sawdust, waste paper, cow dung and rice bran and its admixtures in the following proportions: Sawdust: paper (2:1), rice barn: paper (2:1), cow dung: paper (2:1), Rice bran: sawdust: paper (1:1:1) investigating the bonding properties of paper. The ...

Modification and performance evaluation of a dual-function okra processing device

The performance evaluation of a dual-function device for slicing and drying Okra developed at the Federal College of Agriculture, Ishiagu Nigeria was carried out and reported.  The device was designed to slice and dry okra in one single-sequence operation.  To evaluate the devices, some physical characteristics (the axial length, mean equivalent diameters and sphericity) of okra samples were measured to determine blade distance and other machine considerations.  The results showed ...

Performance evaluation of three coconut cracking devices and comparison with conventional cracking technique

Performance of three coconut cracking devices; punch-split, impact-split, hydraulic-split were carried out and their comparison with conventional (hand cracking technique) evaluated. Each cracking technique was evaluated for capacity, efficiency, ergonomics, and time required to crack a unit of different coconut grades.  The results showed that the average cracking efficiency for punch-split was 87.09 percent with a range of 86.76 to 95.00 percent, impact-split efficiency vari...

Insecticidal Efficacy of Some Indigenous Plant Species against Flea Beetles on Okra

AbstractLeaves and stems of castor oil plant (Ricinus cummunis), Barbados nut plant (Jatropha curcas) and Goat weed (Ageratum conyzoides) were investigated in the field during the 2018 cropping season at Umudike against Okra flea beetles, Podagrica spp (P. uniforma and P. sjostedti) for their insecticidal efficacy. NH47-4 Okra variety was used in the trial. The experimental design was Randomized Complete Block Design (RCBD) with seven treatments and four replicates. Results showed that the pl...

Heavy Metals Bioremediation Of Agricultural Soil Using Poultry Litter

The aim of this research is to determine the level of heavy metals contamination of agricultural soil and to reduce its concentration in the soil. Soil sampled at Inua Eyet Ikot, Mkpanak, Ibeno Local Government Area of Akwa Ibom State was analyzed to check for the initial heavy metal concentration of the soil. Poultry litter as a nutrient additive bearing microorganisms, bacteria and fungi was introduced to the soil to reduce the concentration of heavy metals. The sampled soil was mixed with ...

EFFECT OF FEEDING VARYING LEVELES OF COWPEA AND GROUNDNUT HAULMS ON GROWTH AND HEAMATOLOGICAL PARAMETERS OF RED SOKOTO GOATS

ABSTRACTThe study was conducted to determine the effect of inclusion level of cowpea haulms and groundnut haulms on the growth performance and haematological parameters of Red sokoto goats. Nine goats were allocated to three dietary treatments which were formulated to contain 40% cowpea haulms, 40% groundnut haulms and 20% cowpea ː 20% groundnut inclusion. In a Completely Randomised Design (CRD). Each animal was fed 2.5% of the body weight of the experimental diet for a period of 12 w...

The objectives of the study were to describe the socio-economic characteristics of rural women, describe the types of agroforestry practices, examine the sources of information on ageroforestry, find out the level of knowledge of rural women on agroforestry practices, ascertain the attitude of rural women toward agroforestry practic...

Design and Construction of an Integrated Mechanized Cassava Mash and Garri Sifter (Sieve)

Cassava is produced in a large quantity in Nigeria. One of the products emerging from its processing has turned out to be a major staple food in the nation, which is ‘garri’. Due to insufficient and inadequate processing equipment; cassava has been susceptible to wastage and ‘garri’ production has been reduced in scale, thereby resulting in insufficiency and high cost of ’garri’ in the market. In order to ease the production process, a compact mechanized cassava mash/‘garri...

Biochemical and biometrics characterization of five varieties of Pistacia vera L. grown in Maoussa experimental station (northwest of Algeria)

Both biometric behavior study and fruit biochemical analysis of five varieties of Syrian Pistacia vera introduced in Algeria in 1998 and raised in semi-arid bioclimatic stage (common Maoussa, Mascara, Algeria) led to a qualitative comparison. Based on the pistachio descriptor criteria established by the International Plant Genetic Resources Institute in 1997, characterization and descriptor of female varieties of pistachio were performed. The obtained results allow the bet...

Comparative Study of The Emergence and Growth of Young Seedlings of Five Varieties of Pistachio (Pistacia vera L.) of Syrian Origin

The present work is to study the emergence and growth of seedlings of five pistachio varieties that are: Batouri, Achouri, Neb-Djemel, Adjmi and Bayadhi. The study was conducted in a greenhouse temperature and photoperiod were controlled. The seeds are germinated in pots filled with peat without going through the damp cold stratification at a temperature of 4ºC. The results obtained showed that growth parameters (length and diameter of the plants) revealed significant tes...
