The Secretary of State for the Environment said a review of the Government's main policy statement could lead to big changes.
Weight-based targets, planning policy and new technologies will all come under scrutiny as the UK looks for better ways of managing its rubbish.
The Government launched Waste Strategy 2000 five years ago as the EU started producing a raft of waste laws for member states to adhere to.
That strategy is now undergoing a planned review, and Beckett has insisted there could be big changes in policy.
She said: "Local authority and national recycling targets are to be reviewed this year as part of an interim review of the Waste Strategy 2000.
"I'm certain the question of whether targets should be based on weight is exactly the kind of issue we will look at.
"I hope everyone will take the opportunity to look at the whole issue of waste-management so we can make progress."
Beckett was talking to delegates at the Associate Parliament Sustainable Waste Group's Waste Strategy and New Technologies conference in London last week.
On planning policy changes, she said: "We are addressing concerns that the planning system will not allow for the kind of growth in infrastructure that we need."
And she added: "The role of new technologies is an important one. It is vital that we deliver real improvements in waste management so that we meet the challenges of the future.
"As we have just started a review of Waste Strategy 2000, the discussions today will prove to be particularly useful."
