The main ingredient of disposable corn starch tableware material is starch PP mixture with starch content more than 45%. The utility model has the advantages of low cost, no influence on the strength and toughness of traditional plastics, conforming to the current food safety standards, reducing carbon emissions and saving oil resources.

因淀粉是物理改性，置于潮濕環(huán)境會(huì)引起發(fā)霉等問(wèn)題，所以玉米淀粉材質(zhì)大多用于一次性制品，如一次性餐具，保鮮膜，垃圾袋等。

Because starch is a physical modification, it can cause mildew in humid environment, so the material of corn starch is mostly used in disposable products, such as disposable tableware, fresh-keeping film, garbage bags, etc.

就焚燒處理方式而言，生物基原料如淀粉秸稈等，來(lái)源于植物，所以使用生物基產(chǎn)品可以減少對(duì)CO2對(duì)大氣排放的影響。所以在產(chǎn)品具備其使用性能的同時(shí)，增加生物基的含量，對(duì)環(huán)境的影響小，對(duì)不可資源的依賴越小。但是，單純從處理方式來(lái)考慮對(duì)環(huán)境的影響是片面的，需要考慮其原料到制品對(duì)水電等資源的消耗或者產(chǎn)生的環(huán)境污染，從而來(lái)整體判斷某種材質(zhì)的優(yōu)性。

As far as incineration treatment is concerned, biomass materials such as starch straw are derived from plants, so the use of biomass products can reduce the impact of CO2 on atmospheric emissions. Therefore, while the product has its performance, increasing the content of biological base will have less impact on the environment and less dependence on non-resources. However, it is one-sided to consider the environmental impact only from the way of treatment. It is necessary to consider the consumption of water and electricity resources or the environmental pollution caused by the raw materials and products, so as to judge the overall superiority of a certain material.

從環(huán)保角度和資源節(jié)約角度評(píng)價(jià)，要從整體生命周期來(lái)看，即從原料到制品，制品使用后的垃圾處理。資源消耗方面，主要為原料的成分，電力消耗使用的石化資源。環(huán)境方面，電力消耗的石化資源以及焚燒處理排放的CO2等溫室效應(yīng)氣體，以及污水廢棄排放。

From the point of view of environmental protection and non-renewable resources conservation, we should evaluate the whole life cycle, that is, from raw materials to products, waste disposal after the use of products. In terms of resource consumption, petrochemical resources are mainly used in the composition of raw materials and power consumption. In terms of environment, fossil resources consumed by electricity, greenhouse gases such as CO2 from incineration treatment, and wastewater discharge.

生物基制品，資源消耗方面，它的原料部分為淀粉，對(duì)糧食的利用率高，制程簡(jiǎn)單，所以成本也占有很大的優(yōu)勢(shì)。對(duì)比傳統(tǒng)石油基塑料，一定程度上節(jié)約石化資源。環(huán)境方面，所產(chǎn)生的垃處理方式主要是分離處理，石油基塑料回收，淀粉部分堆肥處理，對(duì)環(huán)境影響小。但是實(shí)際情況中大多數(shù)為填埋或者焚燒。焚燒主要的污染為石油基部分的產(chǎn)生的額外增加到大氣中CO2，但是可以進(jìn)行能源回收。如果處理方式為填埋，通過(guò)淀粉的生物降解而致使整個(gè)材料物理性能崩潰，但這種“崩潰”后剩余的部分PP還是會(huì)殘留在土壤中，長(zhǎng)時(shí)間占據(jù)空間資源。

Bio-based products, resource consumption, its raw material part is starch, high utilization of grain, simple process, so the cost also has a great advantage. Compared with traditional petroleum-based plastics, petrochemical resources can be saved to a certain extent. In the aspect of environment, the main waste disposal methods are separation, recovery of petroleum-based plastics and composting of starch, which have little impact on the environment. But in reality, most of them are landfill or incineration. The main pollution from incineration is the extra CO2 generated from petroleum-based components, which can be recovered from energy sources. If the treatment method is landfill, the physical properties of the whole material will collapse due to the biodegradation of starch, but the remaining part of PP after this "collapse" will remain in the soil and occupy space resources for a long time.

從一次性餐具而言，因?yàn)槭澄镏赜椭卣{(diào)料，而一次性餐具受殘留食物的污染，所以導(dǎo)致其回收難或者不具備回收價(jià)值，食物混合堆肥對(duì)土壤影響大。所以實(shí)際處理中多為填埋和焚燒。以焚燒方式為例，對(duì)比以上兩種材質(zhì)，PLA的優(yōu)點(diǎn)為節(jié)約大部分石化資源，減少對(duì)環(huán)境CO2的排放，缺點(diǎn)是成本高，浪費(fèi)糧食。玉米淀粉的優(yōu)點(diǎn)為成本低，部分節(jié)約石化資源和較少CO2溫室效應(yīng)的氣體對(duì)大氣的排放。缺點(diǎn)是石油基組成部分仍然會(huì)對(duì)環(huán)境造成一定的污染。以填埋方式為例，PLA的優(yōu)點(diǎn)是節(jié)約大部分石化資源，缺點(diǎn)是成本高，浪費(fèi)糧食資源，不易降解，仍然無(wú)法解決對(duì)空間的長(zhǎng)時(shí)間占用問(wèn)題。玉米淀粉的優(yōu)點(diǎn)是節(jié)約部分石化資源，可部分崩潰降解較少土地占用問(wèn)題，成本低。缺點(diǎn)是石油基組成部分仍然造成對(duì)環(huán)境的空間占用問(wèn)題。

As far as disposable tableware is concerned, because Chinese food is heavily oily and seasoned, and disposable tableware is contaminated by residual food, it is difficult to recycle or has no recycling value. Food composting has a great impact on soil. So the actual treatment is mostly landfill and incineration. Taking incineration as an example, compared with the above two materials, PLA has the advantages of saving most petrochemical resources and reducing CO2 emissions to the environment, but its disadvantages are high cost and waste of grain. Corn starch has the advantages of low cost, partial saving of petrochemical resources and less CO2 greenhouse gas emissions to the atmosphere. The disadvantage is that petroleum-based components still cause some pollution to the environment. Taking landfill as an example, PLA has the advantage of saving most petrochemical resources, but its disadvantage is high cost, wasting food resources, not easy to degrade, and still unable to solve the problem of long-term space occupation. Corn starch has the advantages of saving part of petrochemical resources, partially collapsed and degraded, less land occupation and low cost. The disadvantage is that the petroleum-based components still cause space occupancy for the environment.
