Solving the problem of waste disposal

Solving the problem of waste disposal
With the amount of rubbish being produced around the world increasing, Mark Rowe asks whether a new generation of incineration plants can help to solve the problem.
A
A. For many years, burning rubbish has been portrayed as the lazy option when it comes to dealing with the problem of waste disposal, since it sends toxic fumes into the air and appears to support a consumerist, throwaway society. Norway, however, appears to be burning its way through a sizeable chunk of Europe's municipal waste, using the heat created by this process to warm and power homes in many of its cities. Norway isn't alone: Germany, Sweden, Belgium and the Netherlands all burn significant quantities of rubbish, and across Europe there are 420 plants burning municipal waste. With Europe dumping 150 million tonnes of rubbish into landfill every year, there would seem to be limitless supply.
B
B. Those who support burning waste say that a new generation of incinerators have made it a more attractive option. Filters and scrubbing mechanisms now capture harmful substances such as mercury, hydrochloric acid and heavy metals. According to Ted Michaels, president of the US-based Energy Recovery Centre, 'There has been constant evolution in combustion engineering and emissions-control technology, and the output from these facilities is now minuscule.' Above all, however, supporters say that incineration is the only way of preventing the long-term impacts of landfill. In ten years' time, says the World Bank, humans will be generating 2.2 billion tonnes of solid waste per year. Advocates see incineration as a practical way to deal swiftly with an immediate problem.
C
C. Levels of waste generation vary hugely around the world. 'It's a problem for the developed nations,' says Joergen Fenhann, a senior scientist working with the UN Environment Programme in Denmark. 'The more you develop, the more you produce, buy and throw away.' But the growth of incineration hasn't been universally welcomed. Lars Haltbrekken, chairman of Friends of the Earth in Norway, is concerned that incineration plants appear to generate demand for their services. 'The problem in Norway,' he explains, 'is that we have built too many waste-burning factories. So we've ended up importing waste from other countries. If you look at this in a very small perspective, it is, of course, better for the climate to burn rubbish from the UK rather than leave it in landfill there,' he continues. 'But in a broader perspective, it's a lazy way of getting rid of waste; you don't stimulate the goals of reducing, reusing and recycling.'
D
D. Incineration is also at odds with EU policy, which promotes a 'recycling hierarchy': ideally, we simply produce less waste in the first place; failing that, we reuse objects more; the next best option is recycling; only then should we consider incineration, while dumping in landfill is the last resort. Dealing with the problem of waste disposal involves tracing the whole process that took the material from its inception to landfill. We used to call this the 'cradle to grave' life cycle; now, the talk is of 'cradle to cradle' and an even more comprehensive concept known as 'zero waste'. 'The philosophy of cradle to cradle is about designing products that are actually good for the environment at the end of their life,' says Joan Marc Simon, European spokesman for the environmental movement GAIA. 'You design a bottle that contains no toxins, is fully recyclable and requires the minimum amount of energy to be produced.' As Simon points out, however, without the right mechanisms in place, 'nothing guarantees that this bottle will end up being properly collected and treated in the appropriate recycling facility.'
E
E. Tim Burns, policy manager at Keep Britain Tidy, says, 'In the UK alone, people waste 10 billion of food every year. You can argue about composting that, or not buying it in the first place—if you do that then that's money the retailers don't get, so it's not always clear cut.' The implications of zero waste are that we're going to have to take a good long look at those well-stocked supermarket shelves, too. 'Supermarkets keep their shelves stocked even when demand isn't there, which means they have to pay to dispose of a lot of food,' says Burns. 'But that cost is less to them than the cost in brand damage of having empty shelves.'
F
F. Recent history and changes in trends in recycling suggest that we should be prepared for unexpected developments. 'If someone back in the 1980s had suggested what waste would be like now, they would be completely wrong,' says Richard Fisher, a PhD researcher at Cranfield University. 'Consumerism has developed at a pace we never expected. Nobody would have said there would be so much electronic waste. But recycling has grown, too—ten years ago nobody would have predicted today's levels of recycling.' But he points out that the need to reduce waste is still a difficult message to sell to consumers. He suggests that what people are really concerned about is their loved ones and the future they face. 'Perhaps we can align the environmental message to these deep-seated values,' he says. 'We need to look at whether it's business that drives consumers or the other way around. You need government to play a leadership role, whereas countries such as the UK seem to be stepping away from the environment in pursuit of short-term economic goals.'

What recent history tells us about recycling

Richard Fisher, a researcher from Cranfield University, points out that the pace of consumerism has increased more quickly than was predicted in the 1980s. There has, for example, been unexpected growth in waste from ﻿ products. He suggests that the need to protect the environment should be linked to basic values, and adds that it might be better if consumers had more influence over ﻿ and more direction was provided by ﻿.

🔥 Answer key (đáp án và giải thích)

Giải thích chi tiết

Ứng dụng Linearthinking để giải quyết dạng Matching Headings

Step 01: Read relevant information to understand (main idea – không cần đọc detail)

Dựa vào phần Simplify & Connection ở trên, có thể suy ra:

→ Đại ý toàn đoạn: Một số quốc gia châu Âu (Norway + neighbours) đang áp dụng cách xử lý rác gây ngạc nhiên – đốt lượng lớn rác để lấy nhiệt/điện – trái ngược định kiến “lười biếng”.

--------------

Step 02: Compare meaning with meaning

Đại ý đoạn: Cách tiếp cận xử lý rác bất ngờ (đốt rác) được nhiều nước áp dụng.

Chọn đáp án đúng: D. A surprising approach to waste disposal by several countries.

- Giải thích: Đáp án nêu đúng hai yếu tố then chốt – “surprising approach” (đốt rác từng bị coi tiêu cực) và “several countries” (Norway, Germany, Sweden, Belgium, Netherlands).

• Lưu ý: Nếu chỉ scan từ khóa “incineration”, “lazy”, “landfill”, người đọc dễ nhầm với G (justifications for incineration) hay F (arguments against…) vì đều có cụm từ tương tự. Hiểu đại ý mới thấy trọng tâm của đoạn là SỰ NGẠC NHIÊN về NHIỀU QUỐC GIA chọn đốt rác.
