包括废弃物在内的污染管理
防止污染的措施
滨松光子学株式会社努力防止污染。我们的生产设施，其中大部分位于日本，在制造过程中使用一系列化学品，其中一些特定化学品可能会污染环境。根据日本法律，这些化学品的所有转移和排放必须通过污染物排放登记 (PRTR) 系统向政府报告。我们根据每年两次的化学品使用调查得出的数据，向竞争主管机构适当报告。
对于我们工厂使用的化学品，将通过上述化学品使用调查以及滨松集团的化学物质绿色采购管理标准进行管理*1。这些物质在处置阶段受到谨慎管控。日本环境基本法案列出了七种可能对人类健康和生活环境有害的典型污染形式：(1) 空气污染，(2) 水污染，(3) 土壤污染，(4) 噪声，(5) 振动，(6) 土地沉降，(7) 气味。在滨松光子学株式会社，我们根据法律和我们自己的标准，从预防可能导致污染的事故的角度来管理所有这些形式的污染。当我们的业务活动可能会产生污染时，我们会立即采取行动，确定污染的来源，向主管当局和当地社区报告此事，并努力使状况恢复到原始状态。
*1: 滨松集团化学物质绿色采购管理标准：滨松光子学株式会社的内部标准适用于公司指定为环境相关物质的物质。我们还制定了针对供应商的化学物质绿色采购管理标准，该标准设定的标准与滨松集团标准相同，侧重于供应商供应的产品/零部件中包含的化学品，并向公众开放。

适当管理化学品
滨松光子学株式会社每年对化学品使用状况调查两次，以了解其在制造工艺等过程中对化学品的全部使用情况。其中包括 PRTR 系统中指定的 I 类指定化学品*2。当公司每年处理 1 吨或以上此类化学品时，将需要报告。2021 年，总公司工厂和都田工厂报告了 5 种此类化学品的使用情况。滨松光子学报告的化学品、每个财政年度处理的 I 类指定化学品数量*3，及其单位净销售额的输出如下所示。2022 财年，处理量与上一财年持平。 另一方面，由于净销售额增加，每单位净销售额的处理量比上一财年有所提高。
*2 需要在 PRTR 系统下提交排放到环境中的排放量并提供安全数据表 (SDS) 的化学品。截至 2022 年 1 月，已将 462 种物质指定为 I 类指定化学品。

推进 SDS 的收集和使用
SDS 有助于理解化学品的特性并进行安全操作。滨松光子学株式会社确保最新的 SDS 不仅适用于工业安全和健康法案要求提供 SDS 的化学品，还适用于其处理的所有化学品。SDS 记录在公司的数据库中，在化学品风险评估和维护工作场所和周围环境的安全方面发挥作用。
内部 SDS 数据库
减少 VOC 的大气排放
为了减少挥发性有机化合物 (VOC) 的大气排放，滨松光子学株式会社正在减少对这些化合物的使用，并安装回收设备。VOC 主要用于工业清洁设施，此类主要排放物包括乙醇、异丙醇和丙酮。
检查化学品处理状态
虽然对与化学品相关的风险的评估基于 SDS，但实际的风险程度在很大程度上取决于化学品的使用环境。在滨松光子学株式会社，我们在化学品工作组领导下，定期检查操作化学品的工作场所和化学品储存地点。 当通过检查过程发现问题时，我们会及时予以纠正，然后将问题报告给总部化学品工作组，并适当分享信息。
化学品安全培训
为了确保员工妥善处理化学品并防止环境事故，滨松光子学株式会社编制了事故和灾难响应手册，安装和检查了灾难响应设备，并定期举办灾难响应培训课程。培训课程包括有关应对化学品泄漏的培训、为室内气体泄漏做准备的疏散演习以及呼吸器储罐连接培训。
我们还定期为员工举办化学品安全教育计划。为了理解处理化学物质的风险，我们分享内部/外部化学物质事故案例，或邀请外部专家进行专业讲座。
适当的废弃物管理
努力实现零排放
我们以适当的废物处理作为基本方针，一直在妥善管理废物，以实现零排放*4 的理念，从而降低废物对环境的负面影响，并高效利用资源。2020 财年，我们记录的填埋率*5 是 0.2%，并且实现了零排放。这是通过分离和减少废弃物、减少劣质货物、重复使用设备和包装材料以及促进回收来实现的。
*4“零排放”是努力使社会实现零废物弃置的方法。实现这一目标的策略包括减少生产过程中使用的资源和产生的废弃物，同时回收不可避免产生的任何废弃物。根据第三届静冈县回收协会计划的定义，滨松光子学株式会社实现了零排放，该计划是“最终处理（填埋等）率低于 1.8%”，包括废酸和废碱。
*5 填埋率：填埋量与废弃物量的比例
| 2018 财年 | 2019 财年 | 2020 财年 | 2021 财年 | 2022 财年 | |
|---|---|---|---|---|---|
| 输出量 | 1,194 | 1,301 | 1,292 | 1,491 | 1,428 |
| 工业废弃物 | (550) | (541) | (549) | (618) | (657) |
| 有害废物*6 | (271) | (315) | (307) | (404) | (339) |
| 一般废弃物 | (123) | (152) | (149) | (152) | (147) |
| 有价值物品 | (251) | (291) | (287) | (317) | (285) |
| 回收量*7 | 914 | 1,050 | 1,077 | 1,250 | 1,230 |
| 填埋量 | 4.6 | 6.3 | 2.7 | 3.7 | 7.2 |
*6 法律规定为指定危险废物的废物。这些物质包括污泥、废酸和废碱，均含有高于一定浓度的重金属、有机氯化物和二噁英。还包括 PCB、石棉和废汞。
*7 回收量是材料和热回收量加上有价值材料量的总和。
确保在我们的合同废弃物处理设施中妥善处置
滨松光子学株式会社每年都会对我们签约的废弃物处理设施进行全面检查，以确保妥善处理废弃物。我们确认承包商的废弃物处理许可证的详细信息，遵守废弃物处理和公共清洁法案中规定的废弃物处理和储存要求，以及承包商是否与周围住宅社区保持和谐关系。在承包商审计中，我们审查从废弃物运输到填埋的所有流程。如果发生不当处理（幸运的是，公司目前没有案例），公司将依法向主管当局报告。
我们的合同废弃物处理设施正确处置状态的确认次数
| 2018 财年 | 2019 财年 | 2020 财年 | 2021 财年 | 2022 财年 | |
|---|---|---|---|---|---|
| 确认次数 | 21 | 23 | 19 | 24 | 27 |
危险废弃物的适当处置
某些工业废弃物在若干法律和法规中被确定为危险废弃物。5 此类废弃物需要特别注意，并需要妥善处置。我们有委托承包商，其设施以环保的方式进行处置。然后，我们会定期对这些场所进行随访访视，以确认这一点。
特别是，我们严格管理 PCB 废弃物，因为必须在法律规定的截止时间前处置。
解决塑料废物问题
塑料废物造成的海洋污染是全球关注的问题，我们正在努力从我们的运营中回收塑料。
| 2018 财年 | 2019 财年 | 2020 财年 | 2021 财年 | 2022 财年 | |
|---|---|---|---|---|---|
| 塑料废物量 | 143 | 160 | 144 | 155 | 201 |
| 塑料废物回收量 | 134 | 150.3 | 133.9 | 138.5 | 180.9 |
防止土壤和地下水污染
滨松光子学株式会社的制造流程包括排放含有有害物质的废液的工艺。如果导电废液的管道损坏或破裂，导致有害物质泄漏，可能导致土壤或地下水污染。水污染控制法案的修订规定，即使是埋在地下的管道也必须检查泄漏情况。鉴于污染风险更大，必要时将地下管道和储罐放到地上， 此外，鉴于日本地震高发，我们在某些地方引入 柔性管道，防止振动对管道造成损坏。
将埋设的管道放置在地面上，并引入柔性管道
