EVALUATION OF EFFECTIVE MICROORGANISMS TECHNOLOGY IN INDUSTRIAL WOOD WASTE MANAGEMENT
The huge quantity of waste generated from industries pose a major problem of proper and adequate treatment. Many methods have been discovered for proper waste management so as to convert waste into reusable by-products. This research highlights the use of one of the simple and easy methods-Effective Microorganism (EM) Technology. Here, microorganisms from natural sources are used to convert different types of wood residues from a large wood industrial complex into a reusable form. It has ...
BIOCONVERSION OF INDUSTRIAL WOOD WASTES INTO VERMICOMPOST BY UTILIZING AFRICAN NIGHT CRAWLERS (EUDRILUS EUGENIAE)
Large amounts of lignocellulosic waste are generated through forestry and agricultural practices, paper-pulp industries, timber industries, and many agro industries. They pose an environmental pollution problem. One of the most economically viable processes for the conversion of lignocellulosic wastes into useful products is the use of earthworms. This process by which earthworms are used to convert organic materials is known as vermicomposting. In the present study, vermibeds were prepar...
A Feasibility Study on Composite Bricks from Sawdust and Boiler Ash Using Cement as A Binder
The present study was carried out with an objective to analyse the feasibility of composite production using sawdust, boiler ash and cement as raw materials. The study investigated various combinations of sawdust, boiler ash and cement as the raw materials for composite brick production. A total of 24 bricks were made on volume ratio basis of sawdust to cement (1:3 and 1:2), boiler ash to cement (1:3 and 1:2) and sawdust, boiler ash to cement(1:1:1 and 1:1:2). The bricks produced were ...
Control, Automation and Monitoring Of Hardboard Production Process Using PLCSCADA System
Human necessities are increasing day by day where as the factories are running out of resources. To ameet these demands industries need to improve the quality and quantity of their production. Programmable logic controllers (PLCs) have been used for many decades for standard control in industrial and factory environments. Over the years, PLCs have become computational efficient and powerful, and a robust platform with applications beyond the standard control and factory automation. This pa...
Effect of vermicompost produced from industrial wood waste on vegetables under field conditions
To promote the organic cultivation of vegetable crops the department of agriculture and government of Kerala have been supporting several large and small scale schemes in varying localities in the state. In 2014 the department financially supported The Western India plywoods Ltd under this scheme for an organic vegetable cultivation programme. As part of this scheme studies were undertaken to assess the impact of vermicompost produced from wood waste on growth enhancement and productivity...
Deproteinized leaf juice-A novel medium for rhizogenesis in vitro
This short note is the first report on the use of Deproteinized leaf juice(DPJ) as a component of plant tissue culture medium. DPJ is the fraction of the juice extracted from crops that remains after the precipitation of Leaf Protein Concentrate(LPC). It is rich in non-protein nitrogen, total carbohydrates and some unidentified growth factors. In one of our experiments the shoot tips of cowpea and greenpea cultured on a minimal medium with DPJ, showed in vitro rooting from the cut portions in...
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 expected to i...
Softboard as a Novel Wood Fibre-Based Substrate for Hydroponic Systems - A Preliminary Study
Hydroponics or the soilless cultivation is a popular and fast growing sector of agriculture and it has many advantages over soil-based system. It offers opportunities to provide optimal conditions for plant growth and therefore higher yields can be obtained compared to open field cultivation. In the aggregate system of hydroponics, different substrates are currently being used as support to the root system of plants under soilless cultivation. Substrates can be organic such as peat, pine bark...
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...
Preliminary Report on Multiple Harvests of Microgreens from Chickpea (Cicer arietinum) Seeds
Microgreens are edible baby plants with huge potential for leafy vegetable production and many consider this plant-based functional food as the new “Superfood”. Microgreens have many advantages over sprouts and they help to improve the nutritional value of our diet, with their high content of healthy compounds. During the microgreen cultivation, seeding is usually done as a broadcast or in rows and as the seeding density is difficult to recommend, most growers prefer to seed as thickly as...
OCCURRENCE OF MISTLETOE (LORANTHUS SPP.) INFESTATION ON GARDEN CROTON (CODIAEUM VARIEGATUM) AND OTHER HOST TREES
Mistletoes (Loranthus spp.) are one of the major groups of plant parasites, which are found in a wide range of vegetative zones in India. They cause great economic loss to our fruit and timber trees, when compared to any other member of the parasitic family of flowering plants. Some of the well known effects of plant parasites on the host trees are reduction of overall growth rate and vigour, low fruit and seed production; slow drying of branches; predisposition to other pests and diseases,...
Micropropagation of Paulownia fortuneii through in vitro axillary proliferation
Primary cultures were established with nodal segments from juvenile shoots of two-year old Paulownia fortuneii trees from a clonal plantation in Andhra Pradesh.A medium containing half-strength MS salts plus BAP(1 mgL) plus sucrose (2%) produced optimum bud break in the nodal explants
PRESENT STATUS AND CHALLENGES OF WOOD SCIENCE AND TECHNOLOGY EDUCATION IN INDIA
This article summarizes the present status and challenges of academic programmes in the field of Wood Science and Technology (WST) in Indian universities and other institutions, with special emphasis to post graduate education. Though the WST education has been running since several decades in India, there is very slow improvement in terms of the number of institutions offering this programme, when compared to many other professional courses. Now there are only 8 institutions in the country...
