This document provides information about the material properties of paper and boards. It discusses how cellulose fibers are derived from wood and plants to create pulp, which is then processed into paper. Additives are added to prevent moisture transfer and improve properties like absorbency. The document outlines the papermaking process, including pulping wood into fibers, refining, forming a paper web, and drying. Recycling paper is encouraged due to the energy and resources required to produce virgin paper from pulp.
Green Computing and Sustainable Environment – Introduction of E-documents and...AM Publications,India
Green computing” represents environmentally responsible way to reduce power and environmental e-waste. Green computing is the practice of using computing resources efficiently. The goals are to reduce the use of hazardous materials, maximize energy efficiency during the product's lifetime, and promote recyclability or biodegradability outdated products and factory waste. It is known that the demand for computing devices rises as the people seek faster way of doing things. The most important issue is the sustainability or sustainable development and it is the key challenge for the environmentalists today. Quite a number of methods have been suggested to ensure sustainability. One important issue is minimum use of papers. Papers are wastage of natural resources. Papers are produced from wood pulp which leads to deforestation. The production of paper releases many by-products which harms the environment. In the present paper the authors have made a systematic study on various issues while producing printed papers which are not good for the environment as well as for the future generations. The authors also propose the negative impacts of paper on the environment can be negated by using E-documentation.

Development of Wood-Plastic Composite at Dedan Kimathi University of Technolo...IJERA Editor
Disposal of plastics and other solid wastes has been a major problem in Kenya. Most of these wastes can be
recycled through various ways and methods to produce new products. Plastics can be combined with sawdust to
develop composite materials for applications such as in building. In this project, a wood-plastic composite
(WPC) was developed from sawdust and plastic solid wastes.
The composite bore the advantages of both wood and plastics which can be applied in various sectors including
interior design work and in automotive among others, thereby curbing the problem of garbage accumulation in
the environment. The project provides eco-friendly solutions by making best use of the available resources
(wood and plastic resins) thus, finding sustainable solutions to the problem of limited waste dumping sites and
deforestation in the country. The composites were made from PP and HDPE thermoplastics and mahogany
sawdust obtained from our wood workshop in Dedan Kimathi University. From the tests carried out and results
obtained, it was found that, the composite has more advantages than the individual constituent materials.
Water absorption test revealed that all the samples took up water though not as much pronounced as for plain
sawdust. Additionally, the rate of water reduction was found to be excellent. They took less time to release the
absorbed water to the environment meaning that they can be applied in humid or wet environ. The composite
samples were easy to machine since they were easily shaped using a handsaw.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Have you ever wondered how
paper and boards are made and
originally sourced from?
Watch closely the video.
5. PAPER/BOARD SOURCE
Objective - Learner will gain knowledge and
understanding of the primary sources of materials for
producing papers & boards.
Sources of papers & boards
Paper and boards are produced from a
pulp which is a mixture of cellulose fibres
and water (up to 99%).
The cellulose fibres are usually derived
from finely shredded wood. But other
materials can be used to such as bamboo
or hemp to produce paper.
Wood generally provides the best results
and this is why it is used. Woods which
are deciduous and coniferous are used.
With softwoods such as spruce or fir
being the most common.
WHY DO YOU THINK THIS IS USED?

Paper Pulping
Pulp is a mechanical
process which
converts debarked
timber logs into fine
chips which are then
added to a chemical
solution and cooked
under pressure to
produce a paper pulp.
A fibrous liquid for a
desired finish bleaches
or colours the paper.
Pulp & Paper Manufacturing Process.
7. PAPER/BOARD SOURCE
Objective - Learner will gain knowledge and
understanding of the primary sources of materials for
producing papers & boards.
1) Pulping procedure will be done to separate and clean the fibres
2) Refining procedure will be followed after pulping processes
3) Dilution process to form a thin fibre mixture
4) Formation of fibres on a thin screened
5) Pressurisation to enhance the materials density
6) Drying to eliminate the density of materials
7) Finishing procedure to provide a suitable surface for usage
8. PAPER/BOARD SOURCE
Objective - Learner will gain knowledge and
understanding of the primary sources of materials for
producing papers & boards.
Paper Pulping – Sizing
Once the pulping process has been completed the liquid
produced is then beaten with other chemicals or additives.
This process is called ‘sizing’.
Sizing stops the paper from being so absorbent, thereby
allowing it to be printed, photocopied or painted.
Paper with little sizing is more absorbent an example of which is
toilet or kitchen paper.
9. PAPER/BOARD SOURCE
Objective - Learner will gain knowledge and
understanding of the primary sources of materials for
producing papers & boards.
Converting pulp into paper
https://www.youtube.com/watch?v=rLLpCO0TU88
The pulp is fed into a mesh
conveyor belt which drains
as much of the water away,
as possible.
Once it leaves the mesh it
passes through a series of
rollers which squeeze any
excess water the mesh
didn’t. It then goes
through dryer rollers and
then finally calendar
rollers; providing the
desired finish to the paper.
10. PAPER/BOARD SOURCE
Objective - Learner will gain knowledge and
understanding of the primary sources of materials for
producing papers & boards.
Paper & the environment.
Like many materials paper if it is not
disposed off sensibly will end up in
landfill.
In the UK we use on average annually 12
million tonnes of paper. To put that into
perspective it takes 25 trees to produce
one tonne of paper.
MATHS TASK – HOW MANY TREES ARE
USED ANNUALLY THEN?
Trees are important to the environment
because they absorb carbon dioxide and
provide habitats for animals.
Paper in landfill
decomposes giving of
methane which is a
greenhouse gas.
11. PAPER/BOARD SOURCE
Objective - Learner will gain knowledge and
understanding of the primary sources of materials for
producing papers & boards.
Paper & the environment.
Recycling paper and boards is easily and
widely accessible to do so. When paper is
disposed off in a specialised paper bin it is
sent to be graded.
Magazines which are produced out of
high quality glossy paper will produce a
higher quality of recycled paper than a
newspaper would do.
The energy it needs to produce brand new
paper from pulp and those from recycled
materials is between 40-70% more.
THEREFORE RECYCLE YOUR
PAPER/MAGAZINES!
Have you seen
these signs?
12. TEST YOURSELF QUESTIONS
Objective - Learner will gain knowledge and
understanding of the primary sources of materials for
producing papers & boards.
