UNTRADITIONAL WAYS TO RECYCLE

UNTRADITIONAL WAYS TO GET ENERGY Compost heap: Use lime to get the pH neutral (acid pH 0-7, neutral 7, base 7-14) Mulch is made by chipping wood in special wood chippers. Mulch almost always is made from trees that grow in special orchards. You can use mulch: 1)As a fuel. 2)As manure. 3) To reduce the amount of water the soil
