Wood and Horticultural Waste Recycling

In Singapore, 332,400 tonnes of wood waste and 252,600 tonnes of horticultural waste was generated in 2013. The recycling rate is 77% for wood waste and 48% for horticultural waste.

Wood and horticultural waste are usually processed into wood chips for composting, cogeneration or used to make new wood products. Used wood pallets and crates can also be reconditioned.

Let’s take a closer look at wood and horticultural waste recycling:

Wood and Horticultural Waste Recycling in Singapore

Wood waste include pallets, crates, boxes, furniture and wood planks used in construction. Horticultural waste refers to tree trunks and branches, plant parts and trimmings generated during the maintenance and pruning of trees and plants all over Singapore.

Used wooden pallets and crates are usually sent to the recycling companies for repair and reconditioning. The pallets and crates are dismantled and the wood parts are cut to size and fixed back to form new pallets and crates.

Wood and horticultural waste are also sent to recycling companies to be grinded into wood chips. These wood chips can be used for composting, where they are piled together and turned frequently. After a few months, the wood chips would be broken down by microorganisms into mulch or compost.

This video shows a typical grinder for producing wood chips:

The wood chips are also used by some recycling companies to make new wood products. The wood chips are mixed with binders and pressed together to produce pallets, doors and floorings.

Some recycling companies use the wood chips as a fuel in cogeneration plants to produce heat and power simultaneously, whereas other companies process the wood chips and recycle them into charcoal products.

Construction and Demolition Waste Recycling

In Singapore, about 1.69 million tonnes of construction debris was generated in 2013 and the recycling rate is 99%. Construction and demolition (C&D) waste is usually sorted for the recovery of materials such as wood, metal, paper and plastics, and processed into aggregates for use in construction activities.

Let’s take a closer look at C&D waste recycling:

C&D Waste Recycling in Singapore

There are several recycling companies that collect and sort construction and demolition waste to recover useful materials from the waste such as ferrous metals, plastics, paper and wood. Sorting is done manually and by machines such as magnetic separators. The recovered materials are sent to local recycling companies for further processing. Some of the recovered wood can also be reused for construction activities.

The remaining waste after sorting contain materials such as concrete, bricks, gravel and stones, which are then crushed and screened to produce aggregates of different sizes for reuse in construction activities. These aggregates are also used to make recycled concrete products such as precast concrete blocks, drains and road kerbs.
