Solid and hazardous waste slideshow 1: Introduction

Tip number 155: Conserve your sun

Add a conservatory to your home to trap the heat of the sun and cut
your heating bills. Bat make sure you have firmly closing doors
between the conservancy and your house. If you don't, heat will be
sucked from your homne on gloomy days.

Tip number 107: Paper your floor

For extra insulation, lay newspaper under your carpet underlay. Choose
a good-quality underlay that is thick and foamy to the touch, and it
will hold the heat in better.

Tip number 106: Make yourself a log

Instead of throwing away your old newspaper, invest in a log-making
machine that compresses and moistens old newspapers and makes them
into slow-burning logs for your fire or wood-burning stove.
