Answer 1

ANS.(i) four types of waste and the ways to eliminate or reduce them are as follows:-

1. Liquid Waste

Liquid waste is commonly found both in households as well as in industries. This waste includes dirty water, organic liquids, wash water, waste detergents and even rainwater.

You should also know that liquid waste can be classified into point and non-point source waste. All manufactured liquid waste is classified as point source waste. On the other hand, natural liquid waste is classified as non-point source waste.

2. Solid Rubbish

Solid rubbish can include a variety of items found in your household along with commercial and industrial locations.

Solid rubbish is commonly broken down into the following types:

• Plastic waste – This consists of bags, containers, jars, bottles and many other products that can be found in your household. Plastic is not biodegradable, but many types of plastic can be recycled. Plastic should not be mix in with your regular waste, it should be sorted and placed in your recycling bin.
• Paper/card waste – This includes packaging materials, newspapers, cardboards and other products. Paper can easily be recycled and reused so make sure to place them in your recycling bin or take them to your closest Brisbane recycling depot.
• Tins and metals – This can be found in various forms throughout your home. Most metals can be recycled. Consider taking these items to a scrap yard or your closest Brisbane recycling depot to dispose of this waste type properly.
• Ceramics and glass – These items can easily be recycled. Look for special glass recycling bins and bottle banks to dispose them correctly.

3. Organic Waste

Organic waste is another common household. All food waste, garden waste, manure and rotten meat are classified as organic waste. Over time, organic waste is turned into manure by microorganisms. However, this does not mean that you can dispose them anywhere.

Organic waste in landfills causes the production of methane, so it must never be simply discarded with general waste. Instead, look to get a green bin from the Brisbane council, or hire a green skin bin or garden bag for proper waste disposal.

4. Recyclable Rubbish

Recyclable rubbish includes all waste items that can be converted into products that can be used again. Solid items such as paper, metals, furniture and organic waste can all be recycled.

Instead of throwing these items in with regular waste, which then ends up in landfills, place them in your yellow recycling bin or take them to your local Brisbane recycling depot.

If you’re unsure whether an item is recyclable or not, look at the packaging or the diagrams on the lid of your yellow recycling bin. Most products will explicitly state whether they are recyclable or not.

ANS.(ii) four benefits of just-in-time manufacturing are as follows:-

1. Less space needed: With a faster turnaround of stock, you don’t need as much warehouse or storage space to store goods. This reduces the amount of storage an organisation needs to rent or buy, freeing up funds for other parts of the business.

2. Waste reduction: A faster turnaround of stock prevents goods becoming damaged or obsolete while sitting in storage, reducing waste. This again saves money by preventing investment in unnecessary stock, and reducing the need to replace old stock.

3. Smaller investments: JIT inventory management is ideal for smaller companies that don’t have the funds available to purchase huge amounts of stock at once. Ordering stock as and when it’s needed helps to maintain a healthy cash flow.

4. Avoids the build-up of unsold finished product that can occur with sudden changes in demand Less time is spent on checking and re-working the product of others as the emphasis is on getting the work right first time.
