Abstract(J)	従来のリサイクル技術は新たな廃棄物を生む課題があり、特にリサイクルが困難なポリウレタンフォーム(PUF)のリサイクルは重要な課題である。本稿では、副生成物のないリサイクル法を提案し、PUFの原料回収と再生を可能にした炭酸水を用いた加水分解について紹介し、持続可能なPUリサイクルのための課題解決について述べる。 Translation
Abstract(E)	Promoting plastic resource circulation is a crucial challenge for Japan, particularly in the automotive industry, which is transitioning toward carbon neutrality. While 60% of waste plastics are thermally recovered, material and chemical recycling remain underdeveloped. Polyurethane foam (PUF), widely used in automotive applications, poses recycling challenges due to its chemical crosslinking. Conventional recycling methods, such as glycolysis, suffer from high energy consumption and by-product formation. This study introduces carbonated water hydrolysis, an energy-efficient, by-product-free method for recovering polyol (PPG) and amine precursors (TDA). A comprehensive ALL-JAPAN approach is essential for establishing a sustainable and effective PU recycling system.

About search

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.

If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).

Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.

Example) X AND Y → "X and Y (including)" X OR Z → "X or Z (including)"

If AND and OR searches are mixed, OR search has priority.

Example) X AND Y OR Z → X AND (Y OR Z)

If AND search and multiple OR search are mixed, OR search has priority.

Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.

The number in "()" after each item is the number of data that includes that item.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
