Defence of the Leaves (DotL pronounced Dottle)Team Leader: Chew Rong KangAssistant Leader: Chew Tse TengRecorder: Chee Li XiangQuestioner: Chien Pai Yu

Team Mission:To use every single leaf's potential in moderation

to improve our ecology and our lives, and to promote leaf recycling to our society to prevent climate change and global warming through the unnecessary waste of materials.

Initial Research

Theme: Champions of the EarthTask given: Leaf Recycling

Initial Research

• Fallen leaves, considered "landscape waste" are:– left to form mulch– OR gathered and decomposed to create compost– OR collected with other landscape waste and

garbage• takes up valuable landfill space• removes nutrients from the soil• create greenhouse gases when burning

• Why not use this abundant resource to substitute materials and create cheaper, greener products?

Introduction - DeLRI

Project Name: Dead Leaf Recycling InitiativeAcronym: DeLRIProject Duration: January to July 2009Project Slogan:Environmentally Friendly Products with a Leafy

Difference!

DotL DeLRI Survey

A survey was conducted to analyse the public awareness of leaf recycling and to estimate the reaction to DeLRI Products.

Survey Conclusions

From an 90 people audience of mostly students, of which 70% grow plants at home...

Occupation

StudentHomemakerEducatorOther

Survey Conclusions

Over 50% do not use leaves at home, and more than 80% do not know of ways leaves can be

recycled

Used leaves at home?

Aware of methods leaves can be recycled?

Survey Conclusions

Of the people that use leaves at home, 50% use them only for art and decoration

Survey Conclusions

BUT over 50% of people find leaf recycling practical and would do so if they had tools and

instructions

Survey Conclusions

FURTHERMORE, 3/4 of the people feel that there is little risk using DeLRI products

DELRI PRODUCTSLeaf in Frames and Leaf Paper

Our Products - Leaf in Frames

Encased in a subtle wooden frame, the simplistic beauty of a leaf can be captured, admired and kept for a lifetime

• Materials:– Wooden Frame– Wood and Paper (for inside border)– Grade A Leaves

• Creation Process:– Grade A Leaf is slowly dried in silica gel to preserve leaf and

prevent cracking– Inside border is made with wood and paper to beautify the inside

of the frame– Leaf is stuck to the frame with strong glue and sealed airtight

• Advantages:– Beautifies rooms and halls– A piece of nature’s art at almost no cost– Can be made easily by oneself

• Areas of improvements:– A better sealant to prevent decomposition– Use of more than one leaf at a time, montage– Creating our own “leaf-based” frames

Our Products - Leaf Paper (prototype)

A combination of newspaper and leaves, this environmentally friendly Leaf Paper can be used at home as decorations or for

writing!

Our prototype Leaf Paper contains45% leaves!

• Materials:– 6 sheets (3 double sheets) of newspaper– 15 leaves– Water– Bleach– Starch– Basin– Bottle– Deckle– Sponge and PVC cloth

• Advantages:– Useful as decoration, writing small notes, or as a gift– 100% recycled material– Reduces paper needed to be “used” and recycled– Unique and attractive

• Areas of Improvement:– Use of blender to create, smoother and cleaner paper– Use of larger deckle to create standard A4 paper– Mass Producing

Other DeLRI Products

• Leaf-Based Fabric– A mixture of less common cotton with more processed leaf fibres– Could be used in bags or clothes, bio-degradable– Needed complex machinery

• Leaf-Based Fish Food– Reduces amount of vegetable content in fish food– Reduces agriculture for vegetables in fish food– Deemed unacceptable to the public in survey

• Leaf-Based Solid Fuels– Wax and shredded leaves combined to form a fuel– Used for non-cooking, aromatherapy, burning for energy etc.– Reduces need for wood/coal/fuel burning– Difficult to research into as leaves caused smoke– May continue during June Holidays

• Leaf-Based Compost– A fertilizer and soil conditioner– Soil, Sand, Scraps, Leaves– A good alternative to landfill– Decided that public can create by oneself

THE DELRI EFFECTOur hoped outcome and conclusions

The DeLRI Effect

• Positive Effects to the Human Environment– Less farming for new materials– Product may be cheaper than actual ones

• Positive effects to the Physical Environment– Less greenhouse gases emitted from factories– Less trees are used in paper– Less materials needed, less space needed to farm

The DeLRI Effect

• Special properties common in our products– Bio-degradable– Environmentally Friendly

• Why we shouldn't use too many leaves– Removes nutrients from the soil– Destroys some habitats– May upset balance in ecology
